VaporSep® is a unique process that recovers valuable LPG and H2 for reuse. Recovery of heavy hydrocarbons (C3+) or LPG from refinery purge and fuel gas streams is more profitable than sending these high-value components to fuel. LPG components are produced in many refinery operations. Traditionally, absorption and cryogenic systems have been used for the recovery of LPG. However, these technologies require numerous moving parts and/or external chemicals, and have high capital and operating costs. VaporSep offers a simple alternative for recovering LPG from refinery waste streams.

Syngas is produced via partial oxidation of a carbon source (coal, natural gas, or biomas) using oxygen (or air) and steam. Syngas produced from gasification or steam methane reforming (SMR) contains mostly hydrogen and carbon monoxide, desirable constituents that are used as feedstock in refineries, chemical processes and power generation. However, a significant amount of CO2, a greenhouse gas, is also produced as a by-product. Removal of CO2 is desired due to downstream process requirements or to reduce CO2 emissions. Until recently, membranes could not be used in these applications because previously available membranes cannot separate CO2 from syngas.
