Abstract
Numerous natural gas liquefaction technologies for the main gas pipeline are known, however, this process is little used for the potential use of electric energy and is poorly implemented at the GDS, where it is possible to carry out low-tonnage LNG production. The object of research is gas distribution station (GDS) “Novo-Alexandrovka” with a capacity of 45 m3/hour. In the course of the research work the technological scheme of liquefaction of natural gas was developed on the basis of the available parameters at the mentioned GDS. This topic is topical due to the annually growing demand for liquefied natural gas. Currently, the LNG market in Russia especially is not developed due to the lack of proper regulatory governability of use and production, lack of cryo-filling stations and a clear program of development of gas vehicles. It is proposed to introduce a liquefied natural gas unit with a main temperature reduction unit through adiabatic expansion in turboexpander. The paper discover construction decisions and analysis of the dependence of the liquefaction temperature of natural gas on the inlet pressure into the gas distribution network as well as The technical and economic characteristics of the implementation of the liquefaction unit at the “Novo-Alexandrovka”.
