NGL Recovery

IPSI is an industry leader in the design of cryogenic processing facilities for natural gas. IPSI engineers have actively participated in the Gas Processors Association’s Joint Industry Research Program, both as Steering Committee members and as financial sponsors since the 1970s. These activities, augmented by our support of local University research in areas of mutual interest, have underwritten IPSI’s extensive cryogenic properties database and the ability to customize process simulators for specialized applications.
