Southeast Idaho Energy, LLC re-issued it’s air permit for the Power County, Idaho coal gasification project. There were major revisions to the project and therefore the permit had to be re-submitted. The capacity was revised from 3,000 to 4,000 tpd coal and petcoke to 2,000 to 3,000 tpd coal and petcoke. It was revised to include two GE gasifiers (one operating and one spare) instead of one large ConocoPhillips gasifier. It was revised to produce end products of ammonia, urea, and urea ammonium nitrate (UAN) and the production of Fischer-Tropsch diesel fuel was eliminated.
The plant is projected to produce 2.3 million tons per year of CO2. The project plans to capture most of the CO2 that it produces and partner with a CO2 pipeline carrier to distribute the CO2 to Wyoming for enhanced oil recovery (EOH). This scope of work is outside of the coal to liquids project due to different contracting issues and risk profile.
The project schedule is described as:
- Submit revised air permit application April 2008
- Groundbreakingearly 2009
- Phase 1 construction 2009 to 2011
- PHase 1 start-up 2011 to 2012
The plant will spend approximately $50 million to install a cover over the coal handling system. This will reduce the particulates to well under the air quality guidelines. The company is voluntarily including a cover over the coal handling operations, because it is aware of certain past particulate issues.
Water consumption will be optimized. The plant design will be based on zero discharge water design to maximize recycle and minimize waste and discharges.
The project is being developed by Refined Energy Holdings LLC a subsidiary of Green Rock Energy. The proposed site for the project is located on 450 acres southwest of American Falls, Idaho. The Idaho Department of Environmental Quality (IDEQ) is reviewing the air permit application.
