PROBLEM TO BE SOLVED: To provide an improved apparatus for recovering natural gas liquid from a natural gas feed stream.SOLUTION: The apparatus performs a recovery process under a constant pressure without intentional pressure reduction. An open loop mixed coolant is used to supply a reflux stream for a distillation column 20 which is used to provide cooling in the recovery process and recover natural gas liquid. The apparatus is used to recover C+ hydrocarbons or C+ hydrocarbons from natural gas. |
