Blog: Propane dehydrogenation: solving the propylene production puzzle with reliable valves

Propylene is the second most valuable intermediate in the petrochemical industry after ethylene. Are you able to keep your production of propylene up at the right levels to meet increasing global demand? It may be that your propylene production is compromised by an inefficient process. How can better valves help you boost your production and reduce cost?

Different applications require different valve features

Breakthroughs in valve design have made major recent contributions to improving the efficiency levels in a PDH process. With the right valves, this efficiency is available now for the production of polymer-grade propylene without a steam cracker or fluid catalytic cracking unit.

What’s key for this particular application is to make sure that valves you choose offer efficient recovery, while guaranteeing safety under all circumstances.

If you’re uncertain about selecting the correct dryer switching valves for your unit, consider solutions capable of tolerating fluctuations in temperature while keeping bi-directional tightness over a period of several years of operation.

If choosing reactor depressurizing valves are a concern, search from solutions with extremely fast operation – a primary requirement for this function, as they must open instantly at over-pressurization. Also robust stem packing is a must to prevent any leaks that cause loss of product and safety issues.
