LPG consists mainly of propane (C3) and butane (C4) and is widely used as an alternative automotive fuel or as chemical feedstock. For the recovery of LPG, we offer an advanced expander process using cryogenic absorption and a de-ethaniser column, which allows for recovery rates as high as 99.9 %, while minimising energy consumption. The expander process enables higher CO2 content in the feed gas than conventional expander processes. LPG can be fractionated, stored in tanks and loaded for export in the same manner as NGL.
