| description | FIELD: heating. ^ SUBSTANCE: method is implemented on installation consisting of two contours, of which the first one is intended for gas decontamination, extraction of heavy hydrocarbons and nitrogen, and natural-gas liquefaction, the second one being a coolant flow contour wherein coolant flow, subsequent to compression and cooling, is divided into two streams in the ratio of 1:19 to 1:33 in a division unit. A bigger flow of coolant is directed to the heat exchanger for cooling, a smaller one being directed, through a throttle gate, to a stripping column cube. After that, the both coolant flows are subject to blending subsequent to pressure equalising. The method allows for reducing cost of natural gas liquefaction due to cooling of liquefied gas before and after its compression, and cooling of the coolant after its compression with cold water from the Arctic seas and inflowing rivers bays with water temperature not exceeding 277 K, and optimisation of coolant streams distribution. Also, the present method allows for reducing the amount of equipment needed and carrying out decontamination of natural gas supplied for liquefaction from mercury and its compounds. ^ EFFECT: reduced power inputs; optimised coolant streams distribution; reduced amount of equipment needed; decontamination of natural gas supplied for liquefaction from mercury and its compounds. ^ 2 cl, 1 dwg |
