COMMERCIAL AND R&D PROJECTS (Continued)
- TAMPELLA IGCC PROCESS DEMONSTRATION Tampella
Power (C-565)
After having obtained the rights to the Institute of Gas Technology's fluidized bed gasification technology in 1989, Tampella Keeler
began to design and initiate construction of a 10 MW thermal pilot plant at their research facilities in Tampere, Finland. The pilot
plant is considered essential for determining operating parameters for specific coals and for continuing process development in the
areas of in-gasifier sulfur capture and hot gas cleanup. The pilot plant will be operational in early 1991.
The pilot plant is designed so that alternative hot gas filters and zinc ferrite absorber/regenerator design concepts can be
evaluated. The gasifier is 66 foot tall, with an inside diameter ranging from 2 to 4 feet. The gasifier will be capable of operating at
pressures up to 425 psig.
After the pilot plant construction was underway, Tampella turned its attention towards locating a demonstration project in Finland
and one in the U.S. A cogeneration project to be located at an existing papermill has been selected as the basis for the demonstra
tion in Finland. The gasifier will have a capacity of 150 MW thermal which is equal to about 500 tons per day of coal consumption.
The plant will produce about 60 MW of electricity and about 60 MW equivalent of district heating.
In September, 1991 Tampella received support from the U.S. Department of Energy (DOE) to build an integrated gasification
combined-cycle demonstration facility, known as the Toms Creek IGCC Demonstration Project, in Coeburn, Wise County, Virginia
(see project C-580, below). The Toms Creek Project will utilize Tampella Power's advanced coal gasification technology to
demonstrate improved efficiency for conversion of coal to electric power while significantly reducing SO and NO emissions.
- TECO IGCC PLANT Teco
Power Services, U.S. Department of Energy (C-567)
Tampa Electric Company's new (TEC) Polk Power Station Unit #1 will be the first unit at a new site and will use Integrated
Gasification Combined Cycle (IGCC) Technology. The project is partially funded by the U.S. Department of Energy (DOE) under
Round III of its Clean Coal Technology Program. In addition to the TEC and DOE, TECO Power Services (TPS), a subsidiary a
TECO Energy, Inc., and an affiliate of TEC, is also participating in the project. TPS is responsible for the overall project manage
ment for the DOE portion of this IGCC project.
The Polk Power Station IGCC Project will be constructed in two phases. TEC's operation needs called for 150 MW of peaking
capacity in mid-1995, becoming part of the 260 MW of total IGCC capacity in mid-1996. The first phase will be the installation of
an advanced combustion turbine (CT) scheduled for commercial operation in July 1995. This CT will fire No. 2 oil during its first
year while in peaking service. During that year, TEC will complete installation of the gasification and combined cycle facilities
which will be in commercial operation in July 1996.
In addition, part of this DOE CCT project will be to test and demonstrate a new hot gas clean-up (HGCU) technology.
The Texaco Gasification Process has been selected for integration with a combined cycle power block.
Part of the Cooperative Agreement for this project is the two-year demonstration phase. During this period it is planned that
about four to six different types of coal will be tested in the operating IGCC power plant. The results of these tests will compare
this unit's efficiency, operability, and costs, and report on each of these test coals specified against the design basis coal. These
results should identify operating parameters and costs which can be used by utilities in the future as they make their selection on
methods for meeting both their generation needs and environmental regulations.
Project Cost: $600 million
TEXACO COOL WATER PROJECT - Texaco
Syngas Inc. (C-569)
Original Cool Water participants built a 1,000-1,200 tons per day commercial-scale coal gasification plant using the oxygen-blown
Texaco Coal Gasification Process. The gasification system which includes two Syngas Cooler vessels, was integrated with a General
Electric combined cycle unit to produce approximately 122 megawatts of gross power. Plant construction, which began in Decem
ber 1981, was completed on April 30, 1984, within the projected $300 million budget. A 5-year demonstration period was com
Project"
pleted in January 1989. See "Cool Water in the December 1991 issue of the Synthetic Fuels Report, Status of Projects sec
tion for details of the original completed project.
Texaco plans to modify and reactivate the existing facilities to demonstrate new activities which include the addition of sewage
sludge into the coal feedstock, production of methanol, and carbon dioxide recovery.
Texaco intends to use a new application of Texaco's technology which will allow the Cool Water plant to convert municipal sewage
sludge to useful energy by mixing it with the coal feedstock. Texaco has demonstrated in pilot runs that sludge can be mixed with
coal and, under high temperatures and pressures, gasified to produce a clean synthesis gas. The plant will produce no harmful
byproducts.
