A process and apparatus for controlling or reducing the heating value or BTU content of NGL recovered from LNG streams. LNG pipelines have a maximum allowable heating value that LNG must be within prior to entering the pipeline. If the LNG heating value is too high, the components contributing to the high heating value must be removed prior to being introduced in the pipeline. The process controls the heating value of the residue LNG gas stream by splitting a feed stream and warming at least a portion of the feed stream. Substantial differences in enthalpy content and temperature between the two portions of the feed stream exist prior to being sent to a fractionation tower.

Optimized heating value in natural gas liquids recovery scheme

A cryogenic process and apparatus for separating multi-component gaseous hydrocarbon streams to recover both gaseous and liquid compounds. More particularly, the cryogenic processes and apparatus of this invention utilize a high pressure absorber to improve the energy efficiency of processing natural gas for pipeline gas sales and recovering natural gas liquids (NGL) gas from gaseous hydrocarbon streams.
