PROCESS FOR THE RECOVERY OF LIQUIDS FROM NATURAL GAS FROM A FLOW OF FOOD GAS AND APPLIANCE TO SEPARATE LIQUIDS FROM NATURAL GAS FROM A FLOW OF FOOD GAS

摘要

recovery of ngl open pressure refrigeration-iso. the present invention relates to an improved process for recovering natural gas liquids from a natural gas feed stream. the process is performed at a constant pressure with no intentional reduction in pressure. a mixed open-back refrigerator is used to provide process cooling and to provide a reflux flow to the distillation column used to recover liquids from natural gas. the processes can be used to recover c3 + hydrocarbons from natural gas or to recover c2 + hydrocarbons from natural gas.
