SYSTEM AND METHOD FOR NATURAL GAS LIQUEFACTION

摘要

A system for natural gas liquefaction includes a natural gas source for providing a flow of natural gas and a moisture removal system located downstream of the natural gas source. The system includes a first heat exchanger located downstream of the moisture removal system for exchanging heat between the natural gas flow path and a first refrigerant flow path of a refrigerant cycle subsystem. The system includes one first throttle valve located downstream of heat exchanger for expanding the flow of natural gas and causing reduction in pressure and temperature of the flow of natural gas. The system includes a filter subassembly for separating solid particles present in the flow of natural gas. The system includes a second heat exchanger located downstream of the filter subassembly and is configured to transfer heat from a natural gas vapor flow path to a second refrigerant flow path of the refrigeration cycle subsystem.
