High Quality China Natural Gas Liquids Recovery Factories - 10MMSCFD Liquefied Petroleum Gas recovery skid for natural gas – Hengzhong Detail:
Indroduction
LPG ( 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.
Why to recover natural gas liquids: Improve the quality of natural gas, reduce hydrocarbon dew point and prevent liquid hydrocarbon condensation in pipeline transportation; The recovered condensate products are important civil fuel and chemical fuel; The comprehensive utilization rate of resources is provided, which has good economic benefits.
Main equipment:
Light hydrocarbon recovery skid includes process integration skid, compressor skid, mixed hydrocarbon storage skid, instrument and control device.
