Title: 95/01364 Process enhancements in plant operations of Destec's coal gasification plant in Louisiana
Abstract: In April 1987, The Dow Chemical Company (Dow) commissioned and began operation of the world`s largest coal gasification combined-cycle plant called Louisiana Gasification Technology, Incorporated (LGTI). The plant, which is owned and operated by Destec Energy, Inc. (Destec), a Dow affiliate, converts 2,200 tons/day of sub-bituminous coal and 1,500 tons/day of oxygen into 30 billion Btu/day of syngas. This syngas fuels two Westinghouse W501 D5 combustion turbines in Dow`s combined-cycle power generation facility (nominally 160 megawatts (MW) of electricity). The LGTI gasifier capacity, operating on bituminous coal or petroleum coke, could fuel a 230 MW state-of-the-art combined cycle plant with syngas and steam. Dow uses this power at its 1,400 acre chemical manufacturing complex in Plaquemine, Louisiana. The operation of LGTI since April of 1987 has significantly advanced the operability and reliability of the Destec entrained flow coal gasification process. This paper highlights the advances made to the LGTI facility and the Destec coal gasification process during the past several years and, more significantly, the impacts of (1) improved burners, (2) the upgraded/redesigned boiler, (3) improved operational management through regularly scheduled quarterly outages, and (4) successful operation of the dry char particulate removal and recycle system during 1993/94.
