E-Gas, Synthetic Natural Gas Production Plant, 2014, 500,000 TPD, Coal-to-SNG

Description

  1. Overview
    1. Synthetic natural gas production plant (coal to SNG).
    2. New, never used.
    3. Installed and commissioned in 2014.
    4. Capable of converting 2 million tons of coal into 500,000 tons of natural gas per year.
    5. Production is 5,500 mt/day of sub-bituminous coal processed into syngas and catalytically converted to methane.
    6. Utilizes 2 + 1 gasification trains with feedstock of 5,500 tpd of sub-bituminous coal, up to 20% pet coke blend.
  2. Process
    1. Coal gasification of coal.
    2. Heat recovery.
