Expander-type cycles are competitive with other gas recovery processes even when applied to relatively rich gas feeds for a high recovery of only propane plus. These cycles are the most economical to use when (1) ''free pressure drop'' is available between feed and residue gas pressure; (2) product requires demethanization only; (3) feed is very lean and propane plus heavier components are required; (4) a small, unattended, prefabricated unit for LPG recovery is needed; (5) an offshore LPG facility is required to be built on a platform where space and weight allowance is at a premium; (6) a facility is initially built for propane recovery, but is planned for future conversion to ethane recovery; and (7) relatively low-pressure gas feeds (which are usually quite rich) must be processed for a high recovery of ethane. A flow chart for an oil absorption plant is presented.
