PROCESS OF MANUFACTURING PRESSURIZED LIQUID NATURAL GAS CONTAINING HEAVY HYDROCARBONS

摘要

The invention relates to a process of manufacturing a pressurized multi-component liquid from a pressurized, multi-component stream (20), such as natural gas, which contains C5+ components and at least one component of C1, C2, C3 or C4. The process selectively (12) removes from the multi-component stream one or more of the C5+ components that would be expected to crystallize at the selected temperature and pressure of the pressurized multi-component liquid product and leaves in the multi-component stream at least one C5+ component. The multi-component stream is then liquefied (14) to produce a pressurized liquid substantially free of crystallized C5+ components. The removal of C5+ components can be by selective fractionation or crystallization.
