Coal gasification project enters design phase

5 April 2005 – ConocoPhillips has begun work on the Front End Engineering Design package for a 600 MW coal gasification project in Southern Illinois, US.

Chip Troxclair, manager of ConocoPhillips’ gasification programme, said: “This is a key step in the next wave of clean, solid fuelled power generation and co-production plant facilities in the United States.”

The Southern Illinois Clean Energy Centre will use ConocoPhillips’ E-Gas Technology to process coal from the state, which will generate approximately 600 MW of electricity and 95 million cubic feet per day of pipeline quality substitute natural gas at a mine mouth site in Williamson County.

The design project will use Siemens SGT6-5000F combustion turbines as the basis for the Integrated Gasification Combined Cycle (IGCC) facility. Currently, 178 of these turbines are in operation in North America, all powered by natural gas. In order to convert them for this IGCC facility, ConocoPhillips will use models of existing Siemens hardware in conjunction with its E-Gas Technology gasification system.

E-Gas Technology incorporates a proprietary gasification design system that can be applied with gas turbine and steam power generation in an advanced IGCC configuration to produce electric power, as well as co-producing synthesis gas, hydrogen and steam in flexible combinations.

A portion of the funding for the project development was from an award from the Illinois Clean Coal Review Board with additional funding from the state’s Department of Commerce and Economic Opportunity.
