For efficient and safe plastics production, a polymerization unit relies on numerous control and on-off valves. It’s vital to know you can count on those valves to do their job at all times. The selection of the right valve for each step requires careful consideration. And every detail matters when it comes to running a reliable, profitable plant.
Polymerization process valves
Since process parameters need to be under control at all times, control valves are needed in many different places in a plant. They regulate the entire polymerization process – starting from feed valves controlling the feed of raw materials, or catalysts, to isolation valves for isolating the reactor and controlling the cooling water.
The safety-critical emergency valves are only infrequently called upon to relieve rapid reactor overpressure, temperature increases and hazardous release of flammable or toxic materials. But when they are needed, it is imperative they function flawlessly, ensuring high-pressure gases are vented safely to flare.
Always sure?
Are you getting reliable and adjustable cooling, with accurate feed flow and a high utilization rate of your raw materials? Do your current valves allow you to produce enhanced quality polymers? Do you have diagnostic capabilities that help prevent downtime? Are you ready for any emergency – even after long periods with unused valves?
In polymerization, the key to peace of mind is to be certain about the quality and reliability of your control and on-off valves, with the optimal characteristics for your unit.
Benefits of having the right valves
Reliable and adjustable cooling
Accurate feed flow
Better utilization of raw materials
High pressure gases vented safely to flare
Feed flow rangeability, allows different types of polymers to be produced
Possible to produce enhanced quality polymers – ones that require new types of catalysts and metal-seated valves
Reduce downtime with intelligent valve controller diagnostics
