Hot zone valves
In the hot zone, the cracking and subsequent cooling occurs. We offer solutions for each step in this process including on-off and control valves for fuel gas, steam, quench oil, and other process media.
Compression zone valves
The compression zone is where compression, scrubbing and drying of the effluent occurs. Here, we provide valve solutions for secure compressor anti-surge, amine let down, and dryer switching operations.
Cold zone valves
The separation of components from the medium occurs in the cold zone. Here, we provide column control
valves, refrigeration system high pressure drop valves, butadiene valves and many more.
Catalyst regeneration valves
In the continuous catalyst regenerator, the catalyst is repeatedly withdrawn from the reactor, regenerated, and returned to the reactor bed. Efficient operation requires top quality lock hopper block, catalyst addition and removal, and chloride injection and addition valves. Our valves are extensively used in such critical applications.
Dryer sequence valves
Dryers remove hydrogen sulphide and trace amounts of water formed through the catalyst regeneration process. Valves here must withstand fluctuations in temperature while maintaining tightness over years of operation. Valmet's metal seated valves are extensively used in these applications.
