Co-production of electricity and alternate fuels from coal. Final report, August 1995

PDF Version Also Available for Download.

Description

The Calderon process and its process development unit, PDU, were originally conceived to produce two useful products from a bituminous coal: a desulfurized medium BTU gas containing primarily CO, H{sub 2}, CH{sub 4}, CO{sub 2}, and H{sub 2}O; and a desulfurized low BTU gas containing these same constituents plus N{sub 2} from the air used to provide heat for the process through the combustion of a portion of the fuel. The process was viewed as a means for providing both a synthesis gas for liquid fuel production (perhaps CH{sub 3}OH, alternatively CH{sub 4} or NH{sub 3}) and a pressurized, low ... continued below

Description

The Calderon process and its process development unit, PDU, were originally conceived to produce two useful products from a bituminous coal: a desulfurized medium BTU gas containing primarily CO, H{sub 2}, CH{sub 4}, CO{sub 2}, and H{sub 2}O; and a desulfurized low BTU gas containing these same constituents plus N{sub 2} from the air used to provide heat for the process through the combustion of a portion of the fuel. The process was viewed as a means for providing both a synthesis gas for liquid fuel production (perhaps CH{sub 3}OH, alternatively CH{sub 4} or NH{sub 3}) and a pressurized, low BTU fuel gas, for gas turbine based power generation. The Calderon coal process comprises three principle sections which perform the following functions: coal pyrolysis in a continuous, steady flow unit based on coke oven technology; air blown, slagging, coke gasification in a moving bed unit based on a blast furnace technology; and a novel, lime pebble based, product gas processing in which a variety of functions are accomplished including the cracking of hydrocarbons and the removal of sulfur, H{sub 2}S, and of particulates from both the medium and low BTU gases. The product gas processing unit, based on multiple moving beds, has also been conceived to regenerate the lime pebbles and recover sulfur as elemental S.
