Cracking process – Recommended valves :

The contraints related to steam cracking are :
1 – The thermal cracking (Delayed cocking units) phase of the process generates effluent with coke particules. It could be the same issues in case of Steam cracking (Ethane/Ethylene process)
2 – The decoking phase of the process generates coke particules which can drop into the valve body during the opening-closing phase and damage the sealing system.
Guichon Valves proposes a valve design with sliding gate and sleeve combination or double discs and substitution rings to reduce ingress of coke particules. The third generation of Guichon Valves’s transfer Line Valves, TLV0 (Transfer Line Valve), provides reliable, long lasting tight shut-off.
