High Quality China Light Hydrocarbon Recovery Unit Suppliers - Custom LPG recovery skid liquefied petroleum gas recovery plant – Hengzhong

LPG is liquefied petroleum gas, which is produced when refining crude oil or volatilized from the process of oil or natural gas exploitation. LPG is a mixture of oil and natural gas formed under appropriate pressure and exists as a liquid at room temperature.

LPG (Liquefied Petroleum Gas) is widely used as alternative fuel for cars, but is also suitable as a chemical feedstock. It consists of propane and butane (C3/C4).

For the recovery of LPG/C3+ the Engineering Division offer an absorber process, which guarantees recovery rates as high as 99.9 %, while at the same time featuring low specific energy consumption. Furthermore the tolerable CO2 content of the feed gas is higher than for conventional expander processes.

To achieve high C3 recovery rates, Hengzhong implements an absorber column upstream of the deethanizer. Here the feed gas is scrubbed by using a light hydrocarbon reflux coming from the top of the deethanizer. LPG is separated from the heavier hydrocarbons down-stream of the deethanizer using a destillation column.
