high temperature mechanical seal factory

Extreme temperatures characterize many refinery processes. Gasoline boiling between 90° and 220° F seems low when compared to kerosene at 315° to 450° F and gas oil at 450° at 800° F. Asset reliability is critical to running these high-temperature processes round the clock. You can reasonably make the case that every major asset and component is critical to an efficient refining process.

But here I want to emphasize the importance of pumps, mechanical seals, and seal support systems. Without pumps, there is no process. Without the proper seal support systems, high temperatures in seal chambers may damage mechanical seals and lead to pump leakage.

While leakage can cause small problems or big ones, you always need to have the risk of sanctions in your mind, especially in high regulation states like California. And with Bay Area refinery budgets as lean as they are currently, it makes sense to choose the right systems from the start to avoid something costly going wrong in the future.

Several factors contribute to high temperatures in the seal chamber, which in turn leads to mechanical seal degradation. A mechanical seal and seal support system may have been perfectly matched to the initial process, working reliably for years. However, a change to a higher-temperature process can exceed the capability of the mechanical seal and capacity of the seal support system.

At higher temperatures, elastomeric components in the mechanical seal may begin to deteriorate. For example, beyond 300° Fahrenheit (150° C) ethylene propylene components eventually degrade and leak. Some hydrocarbons coke at higher temperatures and impede the free movement of mechanical seal components. And process fluids at high temperatures are prone to vaporize, or flash, across the seal faces, causing fugitive emissions.

With increased temperatures of process fluids, the seal support system may no longer be able to maintain the barrier or buffer fluid temperature or flow rate required to maintain the integrity of a dual seal arrangement. When mechanical seals and seal support systems can no longer ensure pump reliability it’s time to select seals, support systems, and components better suited for the job.

If a change to a higher process temperature is causing unanticipated leakage, consult with your preferred mechanical seal vendor. The materials alone can present an overwhelming number of options as seal technology and design continue to evolve. There are now more choices than ever, including:

⇒ Seal faces—carbon, stainless, ceramic, tungsten, and variants incorporating silicon, graphite, or nickel—engineered for resilience and compatibility with process fluids

The benefit of these choices is the ability to match mechanical seals to the specific needs of the process, maximizing seal performance and reliability.

The mechanical seal requirements of high-temperature hydrocarbon processes are best met with dual/ between seal arrangements. A dual seal support system provides fluid between two seals, buffer fluid at a lower pressure than the process fluid, and barrier fluid at a higher pressure than process fluid.

In contrast to a single mechanical seal arrangement where seal degradation or failure results in fugitive emissions or outright leakage, the two seal arrangement provides a more reliable means of preventing high-temperature hydrocarbons from leaking. Here too, rotating equipment and reliability engineers have a number of dual seal design options to choose from, including:

Face-to-face configurations are used in space-constrained areas that cannot accommodate back-to-back or tandem arrangements. Seals share a common stationary component which, if compromised, leads to leakage. You can select from buffer or barrier fluid options.

Gradual or sudden changes in barrier or buffer fluid pressure provide evidence of problems with seals. An experienced mechanical seal vendor can help you navigate the options available to ensure mechanical seals and their components meet each of your specific needs.

Equally important to the reliable functioning of mechanical seals in high-temperature processes is the selection of seal support systems. The mechanical seal you choose will guide the seal support system plan that best meets your needs.

Seal support systems for dual seals are divided into two categories: buffer and barrier. While that seems to simplify the selection, there are a variety of options for each category. To give you an idea of what’s available, I’ve listed a few of the mechanical seal support system options below.

Circulates pressurized barrier fluid from a reservoir to the dual seals. Use plant nitrogen, bladder accumulator, or piston accumulator to supply seal pot pressure. Any leakage across the process side seal is barrier fluid that lubricates seal faces and migrates into process fluid.

Provides clean, dry pressurized barrier gas (typically nitrogen) to the dual seals from an external source. Any leakage past the atmospheric seal is pure nitrogen.

For each of these plans, there are options to fine-tune the seal support system and provide a greater level of reliability for mechanical seals operating in high-temperature environments. Among the many options you may want to include:

An experienced seal support vendor can save you time and money, helping you select and configure the seal support systems with the right components for each of your high-temperature hydrocarbon pumping needs.

The seals are either bolts, nuts, or washers. Seal bots are commonly used because of their benefits in being reusable, preventing fluids and contaminants from escaping even under high pressure. Nuts are essential on temperature withstanding and compatibility with screws, studs, and bolts, in addition to, easy installation. Moreover, washers can withstand high pressures and are compatible with other seals.

Mechanical seals prevent leakage in equipment with moving parts such as mixers and pumps. It is devised to contain liquid or gas in applications where a rotating shaft goes through a stationary housing or less commonly where the shaft is stationary, and the housing rotates around it.

Industrial seals are designed to prevent leakage, while helping to combine systems or mechanisms together. While seals created for ambient and low temperatures are not extremely difficult, creating seals for high temperature applications is a challenge. This is because standard sealing materials cannot perform well in such conditions for long periods of time. This can result in leakage. Hence, it is important to choose the right manufacturing materials to ensure prolonged seal performance in high temperature applications.

Applications with high temperatures can include ethylene production, steam and gas turbines, solid oxide fuel cells, and industrial exhaust systems. Such applications comprise immense levels of heat, aggressive chemicals, and strong transfer fluids. Due to these elements, the temperatures can be of at least 400oF or above. Traditional sealing materials like mica or graphite lose their physical integrity, and their performance diminishes quickly in such environments. This can result in total leakage, which can be lead to a shutdown, and downtime.

The right type ofsealing materialcan make a huge difference to the performance of an industrial seal in an application. Seal manufacturers recommend the following materials for high temperature applications:

PTFE:Polytetrafluoroethylene is one of the reliable polymer materials. It can resist strong industrial chemicals, and maintain its integrity in temperatures above 500oF for long time periods.

PEEK:Polyetheretherketone is a high performance thermoplastic, and is capable of maintaining its integrity in applications with temperatures up to 500oIt provides excellent resistance to wear, chemicals, and abrasions.

Fluorosilicone:This elastomer material combines high liquid resistance of fluorocarbon, and extreme temperature stability of silicone. With a temperature above 400oF, fluorosilicone O-rings can be exposed to sunlight, and will not degrade due to air, ozone, aromatic, or chlorinated hydrocarbons.

Silicone:A rubber-like polymer, silicone has a high temperature resistance up to 482oThe material is resistant to UV rays, ozone, and oxygen. It has great electrical insulation properties, and high gas permeability. It is mainly used to manufacture aerospace seals, and automobile gaskets.

A successful sealing product depends on the collaboration between the customer and the manufacturer. Customers should provide the right information to ensure that the right material is used, and the manufacturing process is completed precisely. This can lead to the creation of
