BEIJING, Aug 14 (Reuters) - Rongsheng Petrochemical , the listed arm of a major shareholder in one of China’s biggest private oil refineries, expects demand for energy and chemical products to return to normal in the country in the second half of this year.

The Zhejiang-based Chinese private refiner saw profit more than triple in the first half of 2020, bolstered by the launch of its 400,000 barrel-per-day Zhejiang Petrochemical Co (ZPC), according to a stock exchange filing earlier this week.

Rongsheng expects to start trial operations of the second phase of the refining project, adding another 400,000 bpd of refining capacity and 1.4 million tonnes of ethylene production capacity in the fourth quarter of 2020.

“We expect the effects of the coronavirus pandemic on energy and chemicals to have basically faded in spite of the possibility of new waves of outbreak,” said Quan Weiying, board secretary of Rongsheng, in response to Reuters questions in an online briefing.

But Li Shuirong, president of Rongsheng, told the briefing that it was still in the process of applying for an export quota and would adjust production based on market demand. (Reporting by Muyu Xu and Chen Aizhu; Editing by Jacqueline Wong)

Li Shuirong (born 1956) is a Chinese billionaire and businessman, the chairman of the Zhejiang Rongsheng Holding Group[zh], which produces petrochemicals.

In 1989, Li Shuirong founded the Yinong Network Chemical Fiber Factory that produced polyester fiber cloth. After the polyester industry shifted upstream, he founded the Zhejiang Rongsheng Holding Group.

Dr.Rongsheng “Ken” Li is a Principal Senior Technical Fellow based in Huntington Beach, California, who has been awarded for his work in the development of aerospace guidance, navigation and control systems. His story is part of a series celebrating Asian American and Pacific Islander Heritage Month that shares perspectives from employees across the enterprise who are making a difference at Boeing through their leadership and commitment to an inclusive workplace culture.

“At Boeing we are constantly innovating,” Dr. Rongsheng “Ken” Li said. “I’m inspired by the belief that we can always improve. As a leader I strive to and encourage others to create new ideas and better solutions for our customers that will also help move the company forward.”

Ken currently supports Boeing Research & Technology (BR&T) in developing next generation Positioning, Navigation and Timing (PNT) solutions across the enterprise. This includes applications for spacecraft, aircraft, surface vehicles, underwater vehicles, and more.

Ken relocated to the United States to attend the University of Southern California, where he received a full scholarship and a Ph.D. in Electrical Engineering.

He would later join Boeing and work in various organizations including Boeing Network & Space Systems as a key developer of Stellar Inertial Attitude Determination & Control Systems for space assets and spacecraft product lines. His designs are used by more than 30 spacecraft programs.

“Employees of Asian descent have been instrumental in the company becoming a leader in aviation dating back to the 1900s," Ken said. “I’m continuing on the path that was pioneered by trailblazers like Wong Tsoo, Boeing’s first aeronautical engineer.”

Born in Beijing, Tsoo helped design a two-seat biplane known as the Model C, which took flight on Nov. 15, 1916, making him a part of aviation history. The Navy would later purchase 50 Model Cs – Boeing’s first production order.

Ken acknowledges that despite meaningful contributions from Asian leaders like Tsoo throughout history, Asian Americans still face limitations and even discrimination in the workforce, especially when it comes to reaching upper level management positions. As an executive leader of Asian descent, Ken is conscious of the “Bamboo Ceiling” – a concept that refers to the combination of individual, cultural, and organizational factors that impede Asian Americans" career progress inside organizations.

“I enjoy collaborating with the younger professionals and I appreciate that Boeing is similarly committed to amplifying diverse perspectives.” Ken said. “A common understanding across all backgrounds, and having a mutual respect for our shared experiences, will help to close representation gaps and achieve parity in retention rates.”

China Rongsheng Heavy Industries Group Holdings Ltd rose in Hong Kong trading after saying it applied to withdraw a plan to buy a diesel engine maker for 2.15 billion yuan ($338 million) because of the European debt crisis.

"If the withdrawal is successful, the investors will be happy and the cash pressure on Rongsheng will be relieved as there will be savings for Rongsheng," said UOB-Kay Hian Holdings Ltd analyst Lawrence Li.

China Rongsheng, which hasn"t announced new shipbuilding contracts this year and is releasing interim results on Tuesday, said it expects a significant drop in its first-half profit. The stock advance on Monday pared Rongsheng"s decline this year to 48 percent and the index gained 8.4 percent in the same period.

Li Rong Sheng is an Associate Research Fellow of silviculture at the Research Institute of Tropical Forestry, Chinese Academy of Forestry, P.R. China. He has conducted extensive research on cultivation, utilisation, resource distribution, breeding and standardisation of rattans. Dr. Li received his doctorate from the Chinese Academy of Forestry in the field of water use efficiency and dry resistance among rattans in 2003. He is the author of over 50 peer-reviewed research articles, and the writer of 5 Chinese standards on rattan, was a member of Editor Board of the Chinese Journal of World Bamboo and Rattan from 2004 to 2013, and a member of Author Board of the book Bamboo and Rattan in the World.

The country’s largest shipyard outside state control is in discussions with the cities of Rugao and Nantong and some ministry-level departments related to the shipping industry, Rongsheng spokesman William Li said by phone today. The company said July 5 it was seeking financial assistance from the government after a plunge in orders forced it to reduce production and “restructure” its workforce. Li declined to elaborate.

Rongsheng and other Chinese shipmakers are struggling as a global vessel glut makes orders more difficult to win and pushes down prices. China has also identified shipbuilding as an industry with overcapacity, for which authorities won’t approve new projects and will limit financing as part of Premier Li Keqiang’s campaign to reduce the economy’s reliance on exports and investment for growth.

Two calls each to Rugao and Nantong local governments’ media offices seeking comment went unanswered today. Rongsheng has a production base in Nantong, a prefecture-level city that has administrative jurisdiction over Rugao.

“We expect shipyard failures could become a reality in China if current conditions persist,” Barclays Plc analysts Jon Windham and Esme Pau wrote in a report to clients yesterday. “Those yards not facing such harsh financial difficulties could increase their market and pricing power.” The Hong Kong-based analysts lowered their rating on Rongsheng’s shares to “underweight” from “equalweight.”

A third of the shipyards in China, the world’s biggest shipbuilding nation, may be shut in about five years, the China Association of National Shipbuilding Industry said last week. The order book of Chinese shipbuilders fell 23 percent at the end of May from a year earlier, according to data from the shipbuilders’ group.

Rongsheng said last week it may post a net loss for the first half. The Shanghai-based company reported an annual loss of 573 million yuan ($93.5 million) last year and a 50 percent drop in revenue. The Wall Street Journal reported on July 3 that the shipbuilder had laid off about 8,000 workers.

Shares of Rongsheng rose 3.8 percent to 82 Hong Kong cents at close of trading in the city. The stock has plunged 34 percent this year, compared with a 9 percent decline for the benchmark Hang Seng Index.

A.P. Moeller-Maersk A/S, the world’s largest container line, said last month it would pool vessels with it two biggest competitors in an effort to manage overcapacity and raise unprofitable freight rates. Maersk Line, Mediterranean Shipping Co. and CMA CGM SA agreed to cooperate on the world’s three largest trade lanes after seeing “virtually no growth” since the financial crisis in 2008, Maersk Line Chief Trading and Marketing Officer Vincent Clerc said.

Vice Premier Zhang Gaoli said in May that China must “strictly forbid” approvals of projects in industries with overcapacity, including those in the ship-building sector, state broadcaster China Central Television reported. The Economic Information Daily reported today that China will implement “strict” financial policies to curb overcapacity.

“There is a saying in Chinese: ‘Save the one that needs it the most, not the poorest,’” Zhang said. “If Rongsheng’s troubles are temporary, and the company’s other management controls are good, and the company still has a promising future, then yes, the government can step in and give it a helping hand.”

An intense substorm activity persisted for about 20 h from 22:00 UT on 27 May 2017. During this time interval, all four MMS satellites were located in the magnetotail plasma sheet (See Supplementary Fig. 1) and detected several events of ion flow reversal. Here, we concentrate on the event at around 4:00 UT on 28 May when MMS was at [−19.2, −11.3, 3.2] Re in Geocentric Solar Ecliptic (GSE) coordinates. In this event, the Alfvénic ion flow reversed from tailward to earthward and then continued for more than one hour (See Supplementary Fig. 2). In this work, we will concentrate on the time interval of the ion flow reversal shown in Fig. 1. The data from MMS 1 was used unless otherwise stated.

The black arrow marks the temporary excursion (03:58:10–03:58:25 UT) when the spacecraft shortly left the current sheet center and then returned again. b The ion bulk flows. c Three components of the electric field. d The electron bulk flows. The black arrows represent the separatrix regions. e Parallel and perpendicular electron temperatures. f The magnitude of current density (black curve), and the background current density (red curve). g Energetic electron (47–500 KeV) omnidirectional differential flux. h Electron (0.1–30 KeV) omnidirectional differential flux. The shadow area corresponds to the presence of energetic electrons. The area between two vertical black dashed lines at 03:58:07 and 03:58:43 UT represents the X-line region.

The ion flow reversed at around 03:58:45 UT, from tailward to earthward (Fig. 1b) as the spacecraft crossed the plasma sheet from the southern hemisphere (\({B}_{x} < 0\)) to the northern hemisphere (\({B}_{x} > 0\), Fig. 1a). The tailward ion flow \({v}_{ix}\) was down to −700 km/s (0.4 VA) at around 03:58:04 UT, and the earthward flows exceeded 400 km/s (0.24 VA) at around 03:59:50 UT, where VA is 1700 km/s, based on N = 0.1 cm−3 and |B| = 25 nT. It indicates that MMS passed through an X-line region from tailward to earthward. The electron bulk flow \({v}_{ex}\) (blue trace in Fig. 1d) was much stronger than the ion flow and displayed a similar overall reversal at around 03:58:45 UT. Moreover, \({v}_{ex}\) showed a few more reversals with simultaneous enhancements of electric field fluctuations (Fig. 1c), e.g., at around 03:57:30, 03:57:44, 03:59:33, 03:59:40, and 03:59:57 UT (the arrows at the top of Fig. 1d), which could correspond to the separatrix regions. The electric field Ez was mainly positive below the current sheet and negative above it (red trace in Fig. 1c), consistent with the Hall electric field. The electrons were significantly heated to 8 keV during the ion flow reversal (Fig. 1e, h). Based on the analysis above, it is concluded that the spacecraft entered the ion diffusion region during this time interval.

The ion flow \({v}_{ix}\) did not reverse gradually, as reported previouslyBx| was <20 nT and changed the sign several times. It indicates that MMS was basically located around the current sheet center. According to the standard collisionless reconnection modelde) should have been detected. The fact is that many current spikes were detected instead of a single compact electron current layer (Fig. 1f). The current density was very strong, sometimes over 100 nA/m2, inside the X-line region.

Figure 2a–d shows three components and the magnitude of the current density around the X-line region. Jx and Jy were stronger than Jz. Jy was primarily positive. The currents in all three directions (Fig. 2a–c) displayed well-separated spikes, and so did the total current density (Fig. 2d). It means that the current sheet had been fully fragmented. In order to determine the common features of these current spikes, we identified all of the spikes with a local maximum >30 nA/m2 in Fig. 2d (See “Methods, Identification of current spikes”). A total of 254 current spikes were identified inside the X-line region. The relation between the peak values of the |J| spikes and |Bx| can be found in Fig. 3a. Overall, the peak values declined as |Bx| became large, in agreement with the Harris-type current sheet in the magnetotailBx = 0) than those dominated by the perpendicular component (blue points), consistent with the current profile across EDR

The bin size is 10 nA/m2. c, d The histogram of the number and duration of the current spikes. The blue, green, and red bars represent the currents of spikes dominated in the x, y, and z components, respectively. The data used in Fig. 3 are from the time period (03:58:07–03:58:43 UT) marked by two vertical black dashed lines when the MMS was located in the X-line region.

Inside the X-line region, there was a temporary excursion (03:58:10–03:58:25 UT) with a Bx minimum of −18 nT (marked by the black arrow in Fig. 1a). It indicates that the spacecraft shortly left the background current sheet center and then returned. Thus, the speed of the plasma sheet relative to the spacecraft was roughly estimated to be about 250 km/s (See “Methods, Estimation of the current sheet speed”). The duration of the spikes was very short (Fig. 3d) and <180 ms for most of them (90%). Given the various durations between 360 and 90 ms, their thicknesses varied from 5.4 and 1.3 de, where de = 17 km is the electron inertial length based on N = 0.1 cm−3. These current spikes corresponded to FCs. Therefore, a complex three-dimensional FC system was observed in the X-line region, analogous to the web of current filaments in numerical simulations

Because of thin and dynamic FCs in the X-line region, electric field and magnetic field fluctuations were very strong (Fig. 2f, g). The variation of the magnetic field δB and the electric field was intense inside the X-line region. δB was related to the FCs (Fig. 2d, f). The intense disturbed magnetic field was mainly observed at the region with strong current spikes. It indicates that the thin and dynamic current filaments can generate strong magnetic field fluctuations. This relation can be found more clearly in Fig. 4d, e, where FCs in a short interval near Bx = 0 were expanded. In Fig. 4f, the perpendicular electric field \({E}_{\perp ,y}\), \(-{({{{{{{\bf{V}}}}}}}_{{{{{{\bf{e}}}}}}}\times {{{{{\bf{B}}}}}})}_{y}\), \(-{({{{{{{\bf{V}}}}}}}_{i}\times {{{{{\bf{B}}}}}})}_{y}\) are displayed. \(-{({{{{{{\bf{V}}}}}}}_{i}\times {{{{{\bf{B}}}}}})}_{y}\) was close to zero and distinct from \(-{({{{{{{\bf{V}}}}}}}_{{{{{{\bf{e}}}}}}}\times {{{{{\bf{B}}}}}})}_{y}\) and \({E}_{\perp ,y}\). Moreover, the difference between \(-{({{{{{{\bf{V}}}}}}}_{{{{{{\bf{e}}}}}}}\times {{{{{\bf{B}}}}}})}_{y}\) and \({E}_{\perp ,y}\) was evident. It means that the ions and electrons were both decoupled from the magnetic field lines inside these FCs. This situation was the same also inside the whole X-line region (Fig. 2g).

Since the electrons were decoupled from magnetic field lines, the non-ideal electric field would be generated. Considering the difference between \(-{({{{{{{\bf{V}}}}}}}_{{{{{{\bf{e}}}}}}}\times {{{{{\bf{B}}}}}})}_{y}\) and \({E}_{\perp ,y}\) varied largely (Fig. 2g), the non-ideal electric field should be developed non-uniformly in the X-line region. The energy dissipation in the electron frame\({{{{{\bf{J}}}}}}\cdot ({{{{{\bf{E}}}}}}+{{{{{{\bf{V}}}}}}}_{e}\times {{{{{\bf{B}}}}}})\) was intense but randomly negative or positive. The negative and positive values were separately summed in each current bin and the results were shown in blue and green dotted curves in Fig. 3b, respectively. The net \({{{{{\bf{J}}}}}}\cdot ({{{{{\bf{E}}}}}}+{{{{{{\bf{V}}}}}}}_{e}\times {{{{{\bf{B}}}}}})\) within each bin was shown in red. The energy dissipation strongly depended on the intensity of the current density. In the region with weak current (<30 nA/m2), the negative \({{{{{\bf{J}}}}}}\cdot ({{{{{\bf{E}}}}}}+{{{{{{\bf{V}}}}}}}_{e}\times {{{{{\bf{B}}}}}})\) means a dynamo process there. In the region with a current larger than 30 nA/m2, \({{{{{\bf{J}}}}}}\cdot ({{{{{\bf{E}}}}}}+{{{{{{\bf{V}}}}}}}_{e}\times {{{{{\bf{B}}}}}})\) was basically positive. Namely, magnetic energy was released to energize plasma.

Figure 5a shows the power spectral density (PSD) of Bz (black curve) and \({E}_{y}+{E}_{x}\) (purple curve) inside the X-line region. The PSD of magnetic and electric fields both followed the power laws and had a spectral break near the lower-hybrid frequency (flh). Between ion cyclotron frequency (fci) and lower-hybrid frequency (flh), the spectral index of the magnetic field was −2.31, while the electric field had a shallow spectral index (−1.26). Above flh, magnetic and electric fields had steeper spectra, and their indexes were −3.3 and −2.96, respectively. It indicates that the diffusion region had evolved into a turbulent state while MMS crossed it. This turbulence could be generated by the thin and dynamic current network. The FCs were also detected outside of the X-line region (before 03:58:07 UT and after 03:58:43 UT) and were concurrent with the increases in the ion flow \({v}_{ix}\) (Fig. 1b, f). The generation of these FCs can be due to the reconnection outflows as reported previously

Figure 1g and h shows the differential fluxes of electrons in the energy ranges of 47–500 keV and 0.1–30 keV, respectively. The electron fluxes were greatly heightened from 2 to about 300 keV in the vicinity of the X-line region (the shadow area in Fig. 1). The fluxes of electrons above 50 keV increased by two orders of magnitude relative to the background value. This indicates that the electrons were substantially energized up to 300 keV in the X-line region, relative to the thermal electrons <1 keV at around 03:57 UT. The energetic electrons displayed a power-law distribution with a nearly consistent index of 8.0 in the X-line region (Fig. 5b).

Although the energetic electron fluxes maintained a high level in the X-line region, a few further localized enhancements were detected (Fig. 6b) and corresponded to the gray and yellow bars in Fig. 6a. The further enhancements at around 03:58:06 and 03:58:43 UT were clear and correlated to the strong |BZ| (Fig. 6a) at the two ends of the X-line region. At the tailward end (the first bar) with \({{{{{{\rm{B}}}}}}}_{{{{{{\rm{Z}}}}}}} < 0\), the flux enhancement first appeared at around 90° from 50 to 300 keV at 03:58:04 UT, and 3 s later, the enhancements began to occur at 0° and 180° also from 10 to 300 keV (Fig. 6c, d). At the earthward end with \({{{{{{\rm{B}}}}}}}_{{{{{{\rm{Z}}}}}}} > 0\) (03:58:43 UT, the last bar), the flux enhancement was only observed at 90°. Immediately out of the two ends, the ion bulk flow \({v}_{ix}\) was sharply intensified (Fig. 1b). Thus, the two ends with strong |BZ| corresponded to the pile-up regions of the magnetic field BZ. At the pile-up regions, the electrons would be accelerated in the perpendicular direction since the gradient drift was along the induced electric field direction, as suggested in simulations

The yellow and gray bars represent the further localized enhancements of energetic electron fluxes. b Energetic electron (47–300 KeV) omnidirectional differential flux. c Electron pitch angle distribution during 10–30 KeV. d Electron pitch angle distribution during 50–300 KeV; e The total disturbed magnetic energy below the ions scale (the frequency great than fci), |δB|2, and the total flux during 30–300 KeV (pink curve). The blue bar corresponds to an isolated 3D vortex structure. The area between two vertical black dashed lines at 03:58:07 and 03:58:43 UT represents the X-line region.

Inside the X-line region, further flux enhancements were observed at least at four places (around 03:58:13, 03:58:19, 03:58:27, and 03:58:35 UT, yellow bars in Fig. 6a). At around 03:58:19 and 03:58:35 UT, the further enhancements were associated with a peak and a valley of BZ, respectively. The electrons displayed field-aligned bi-directional distribution at energies of 10–30 keV and 90° flux increase at energies of 50–300 keV at these two places (Fig. 6c, d). There was another deep valley of BZ from 03:58:29 to 03:58:32 UT, and energetic electron fluxes were moderately enhanced, with a similar pitch angle distribution to those at the BZ peak and valley mentioned above. Since the similar pitch angle distribution of energetic electrons was observed, the acceleration mechanisms could be the same at those locations and be related to some kinds of magnetic structures. The field-aligned bi-directional distribution of the electrons at the relatively low energy (10–30 keV) indicates these magnetic structures could be closed. The betatron acceleration

Another two further flux enhancements were observed at around 03:58:13 and 03:58:27 UT when no clear peak or valley of BZ was detected. The energetic electrons from 10 to 300 keV exhibited flux enhancements at 90°, and the field-aligned bi-directional distribution disappeared. The 90° flux enhancement for the electrons above 50 keV (Fig. 6d) was persistently observed from 03:58:21 to 03:58:46 UT. Namely, this kind of distribution was common for the electrons above 50 keV inside the turbulent diffusion region. In contrast, the field-aligned bi-directional distribution was primarily associated with the peak or valley of BZ. In addition, the flux enhancement merely at 0° can be occasionally observed, e.g., at around 03:58:20, 03:58:33 UT in Fig. 6d. The complex electron pitch angle distribution indicates the electrons could experience multiple acceleration mechanisms inside the turbulent diffusion region.

The fluxes of energetic electrons at energies of 50–300 keV were collocated in Fig. 6e with the disturbed magnetic field energy density (|δB|2). |δB|2 had much more peaks than the fluxes. In addition to the isolated peaks at the pile-up regions, the electron fluxes kept a relatively high level between 03:58:18 and 03:58:44 UT when amplitudes of |δB|2 peaks were large too. The correlation between fluxes and the disturbed magnetic field energy density indicates that electron acceleration inside the X-line region was related to turbulence. Given the special magnetic structures inside the turbulent diffusion region, the electrons would experience second-order Fermi acceleration
