Purge Gas Processing

  • Monomer Recovery Unit (MRU)

Monomer Recovery - Currently, most of the reactor cycle purge and vent gases from ethylene consuming plants such as gas-phase polyethylene, EO/EG, etc. are flared because cryogenic processes are not sufficiently economical or flexible enough to recover contained monomers.  By cost-effectively adapting the non-cryogenic, absorption-based AET Process technology to the reactor waste gas streams, the hydrogenated reactor byproducts are rejected to the fuel gas system, most all of the contained unreacted monomers are recovered, and the environmental emissions are substantially reduced.  The patented Monomer Recovery Unit (MRU) technology is very adaptable to cope with the wide ranging stream compositions and rates typical of gas phase polyethylene units.  In this innovative process, the heavier components that are present in the reactor waste gas streams are used as the preferred absorption solvent whereby no external solvent is required.
