The HYTEC Ethylene Recovery Unit is an easy
add-on system and can be considered for new and existing process installations.
The purge gas stream containing the ethylene monomer
and inert gas, is
typically pressurised and fed into the membrane system, while the permeate side
of the membrane separation stage is fed back into the existing process gas
compressor’s
suction side. By means of the resulting pressure difference and
the hydrocarbon selective membrane material, the purge gas stream is separated
into off-gas, enriched with inert gas, and
the recycled ethylene-rich permeate
stream. No other equipment or machinery is usually required making this a very
simple and reliable process solution.
The benefits
• Easy installation in new plants and easy retrofit of existing systems
• Easiest solution in comparison to other technologies – only a membrane separator is required
• Very short return on investment
• Low maintenanceThe benefits• Safe and reliable operation• Tailor-made design to meet customer’s codes and specifications
