Title: Ventilation Air Methane on Russian Coal Mines

Completed under funding from the U.S. Environmental Protection Agency by NPO Uglemetan and CMM Energy, LLC

This project defined the amount of methane being emitted from Russian coal mines and the potential for using this wasted resource.  Three reports were produced from the work performed under this contract, as follows:

  • VAM RESOURCE DEFINITION (VAM & BBM) (Task 1)
  • VAM UTILIZATION TECHNOLOGIES (Task 2)
  • PRE-FEASIBILITY STUDIES OF SAMPLE MINES (Task 3)

 

The  Task 1 Report summarizes information about the sources of VAM in the Kuznetsk coal basin, which are based on Rosinformugol data and on information obtained from some coal mines in the region. In the Task 2 Report an analytical overview of modern VAM processing technologies is given, including one of the most recent developments in this direction – a commercially available technology developed by EnerCore (Irvine, CA, USA), based on the use of a gradual oxidizer with a sizable gas turbine.  This system can usemethane-air mixtures with only 1.5% methane concentration to fuel the gas turbine. The Task 3 Report considers the possibility of using the VAM utilization technologies as described in Report 2 at two coal mines. It was found that the two mines can theoretically support two different utilization technologies, as follows: regenerative thermal oxidizers (RTO) can be considered at both mine sites and they can both also accommodate a lean-fuel gas turbine.  Economic analyses of the technologies, as applied at the two coal mines, are also presented in this Report. Copies of these Reports are available from Uglemetan.  Send a request to us via the Contacts provided in this web site.
