Olefin Recovery from a Purge or Slip Stream
C2 and C3 off gas streams
Olefins can be recovered from off gas streams so that valuable olefins are not lost to flare
Polymerization Reactor Purge Recovery
Introducing an Optiperm™ membrane system to a polyethylene, polypropylene, polyisobutylene reactor purge streams allow previously lost olefin product to be recovered.
Ethylene Oxide MEG Reactor Purge
Splitter Enhancement or Replacement
The following examples apply to C2, C3, and C4 splitters.
Olefin Upgrade
A membrane system can be placed on the top product to purify the olefin stream.
Paraffin Upgrade
A membrane system can be placed on the bottom product to purify the paraffin stream.
Total capacity increase
Optiperm™ membrane system at the top and bottom to increase capacity of the whole column
Complete replacement of a splitter
As the Optiperm™ technology matures, a multistage membrane design could completely replace a C2, C3, or C4 splitter.
Other applications
Specialty chemical applications for Optiperm™ vary significantly. But Optiperm has proven its usefulness in C2, C3, and C4 applications.
Upgrading an Existing Stream
Existing Olefin Parrafin Streams can be upgrading to higher olefin or paraffin purities for C2, C3, or C4’s.
Removing Olefins from Refinery Fuel Gas
Propylene and butenes can be extracted from Refinery Fuel Gas with an Optiperm™ membrane system
Alkylation Capacity Increase
Propane and butane are crucial to the production of octane in an alkylation reactor. Installing a membrane system can allow you to capture unreacted isobutane and propane and feed them back to the reactor to increase capacity.
