Method for Liquefaction of Natural Gas by Multi-Component Refrigerant

摘要

1. Technical Result Increase in economy, efficiency and safety of the process. 2. Essence A method comprises liquefying gas stream in a heat exchanger, which is cooled by a closed-loop multi-component refrigeration system to produce a methane-rich liquid product having a temperature above about -112 DEG C (-170 DEG F) and a pressure sufficient for the liquid product to be at or below its bubble point. The liquefied gas product is then introduced to a storage means (50) at a temperature above about -112°C. 3. Field of Application Chemical technology, in particular liquefaction of natural gas Table: 7
