Technical and technological solutions for the coal bed methane liquefaction projects

The paper presents technological and cost studies aimed at substantiating selection of technical and technological solutions in the coal bed methane liquefaction projects on the example of Naryksko-Ostashkinskoye and Taldinskoye methane-coal deposits in Kuzbass. Required capacity of the coal bed methane liquefaction plant is substantiated taking into account phasing of the capacity commissioning. Results of technological calculation of the preferred cycles of the coal bed methane liquefaction, as well as estimate of the cost of the main technological equipment of the compared options, are presented. It is concluded that it is necessary to adapt the initial deposit development project to the schedule for commissioning capacities of the coal bed methane liquefaction, and that using the SMR cycle is preferable.
