BORSIG Ethylene Recovery Unit for EO/EG Production

The BORSIG 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.

The benefits

  • Many references for different licensors
  • High recovery rate
  • Quick installation and easy implementation by package unit design
  • Safe operation, high reliability, low maintenance
  • Short return on investment period
