Abstract
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 (); (b) dividing the feed stream () of step (a) to provide at least a first feed stream () comprising at least 90 mass % of the initial feed stream (), and a second feed stream (); (c) liquefying the first feed stream () of step (b) at a pressure between 20-100 bar to provide a first liquefied natural gas (LNG) stream (); (d) cooling the second feed stream () of step (b) to provide a cooled feed stream (); (e) combining the first LNG stream () of step (c) with the cooled feed stream () of step (d) to provide a combined LNG stream (); (f) reducing the pressure of the combined LNG stream () of step (e); and (g) passing the combined LNG stream () of step (f) through a flash vessel () to provide a product LNG stream () and a gaseous stream ().
