Abstract

Liquefied natural gas (LNG) is expedient to making nearby with gas-distribution stations (GDS). In these cases the units of liquation use the pressure drops between main and distributive gas pipe lines. Such units can make over 1–10 т/h of LNG which will be delivered to consumers in radius up to 200 km. For comparison of technical and economic parameters of units the variants of their creation are considered on the basis of modern technologies of gas liquation on GDS: with a vortex pipe or throttling; with expansion of gas in radial expanders or wave expanders; with recuperation of LNG cold resource; from two or three-cascade external cooling. The received results to enable the choose of concrete circuits of small-tonnage production of LNG in view of the predicted cost of gas liquation in depending on gas pressure in the main pipeline and its charge.
