发明名称 Method and apparatus for liquefying a hydrocarbon stream
摘要 A method of liquefying a hydrocarbon stream such as natural gas from a feed stream, the method at least comprising the steps of: (a) providing a feed stream (10); (b) dividing the feed stream (10) of step (a) to provide at least a first feed stream (20) comprising at least 90 mass % of the initial feed stream (10), and a second feed stream (30); (c) liquefying the first feed stream (20) of step (b) at a pressure between 20-100 bar to provide a first liquefied natural gas (LNG) stream (40); (d) cooling the second feed stream (30) of step (b) to provide a cooled feed stream (50); (e) combining the first LNG stream (40) of step (c) with the cooled feed stream (50) of step (d) to provide a combined LNG stream (60); (f) reducing the pressure of the combined LNG stream (60) of step (e); and (g) passing the combined LNG stream (60) of step (f) through a flash vessel (12) to provide a product LNG stream (70) and a gaseous stream (80).
