Russia's first typical mini-plant for the production of liquefied natural gas

Abstract

The principal technical solutions for a typical mini-factory commissioned by ZAO-Sigma-gas in the town of Peterhof (Saint-Petersbourg) on the basis of previous liquefaction plant are presented.

To increase refrigerating capacity of the main1 throttle separation cycle an external refrigerating circuit for high pressure gas hased on a two-stage freon refrigerating machine K-127 was used.

An increase in working pressure of the cycle I from 120-140 bar to 180—190 bar with the substitution of the recuperative heat exchanger I for the heat exchanger developed by ООО I Intellect was also a contributing factor in essential increase in refrigerating capacity о the installation.
