The HYTEC Ethylene Recovery Unit enables the recovery of valuable ethylene monomer from the cycle gas purge. Typically the purge gas first enters an inlet filter in order to
remove droplets before entering the hydrocarbon-selective membrane stage. In the membrane stage ethylene is separated from argon and nitrogen. The ethylene-rich stream is
routed to the suction side of the reclaim gas compressor whereas the ethylene-depleted stream is routed to the boiler unit.![]()

? Easiest solution in comparison to other technologies – only a membrane separator is required
? Very short return on investment
? Low maintenance
? Safe and reliable operation
? Tailor-made design to meet customer’s codes and specifications
