METHOD OF LIQUEFYING NATURAL GAS AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2011 - IPC F25J1/00 F25J3/02

Abstract RU 2414658 C2

FIELD: chemistry.

SUBSTANCE: apparatus for liquefying natural gas includes an improved column for removing heavy hydrocarbons with condensation of the overhead fraction and refluxing. In particular, a methane-rich stream coming from the propane cooling agent cycle enters the column for removing heavy components and vapour from this column with low content of heavy components at least partially condenses, and a portion of this liquid is used as the reflux of the column for removing heavy components.

EFFECT: invention provides wide variety of the composition of the crude stream and working conditions.
