METHOD FOR LIQUEFYING A FLOW RICH IN HYDROCARBONS |
摘要 |
A process is described for liquefaction of a hydrocarbon-rich stream, especially a natural gas stream, at least indirect heat exchange taking place between the hydrocarbon-rich stream to be liquefied and the refrigerant mixture of at least one refrigerant mixture circuit, and the refrigerant mixture being separated after completed supercooling into a gaseous fraction and a liquid fraction and these fractions being recombined before and/or during the reheating of the refrigerant mixture. According to the invention, a gas fraction ( 9 ) that is identical or similar in composition is added at least from time to time to the gas fraction ( 4 ) that has been obtained in the separation (D). In doing so, the addition of the gas fraction ( 9 ) that is identical or similar in composition takes place when a minimum amount of the gas fraction ( 4 ) obtained in the separation (D) of the refrigerant mixture is not reached. |
