Abstract

The relevance of research in the field of designing coal-fired plants using cogeneration technologies aimed at improving the technical and economic efficiency of their efficiency is substantiated. The directions of utilization and processing of the associated methane gas using stirling technologies to obtain the final product in the form of LNG are considered. The main technological processes of liquefied natural gas production and fundamentally important distinctive features of Stirling technology are considered. The main limitations in the choice of cryogenic cycle and liquefaction technology are described.

Keywords

Stirling technologies, Mine methane, Liquefied natural gas, Gas engine fuel, Cryogenerator, Dump truck transport.
