FREMGANGSMAADE OG ANLAEG TIL KONDENSERING AF NATURGAS |
摘要 |
A process and apparatus is described for liquefying natural gas using two closed cycle, multicomponent refrigerants wherein a low level refrigerant cools and liquefies the gas by indirect heat exchange and a high level refrigerant cools and partially liquefies the low level refrigerant by indirect multistage heat exchange. The high level refrigerant is phase separated in order to use lighter refrigerant components to perform the final lowest level of refrigeration while the liquid phase of the separation is split and then expanded for refrigeration duty in order to avoid multiple flash separations wherein heavier components are used to provide the lower levels of refrigeration. |
