Capital Projects
Boulder, Colorado
Power Ecalene Fuels is currently constructing a single tube reactor system in
Boulder, CO. This single tube reactor will house a new and novel way of
suspending the catalyst. It is anticipated that this system will be very efficient in
converting syngas into Ecaleneand will be up and running in May 2008.
Raleigh, North Carolina
Proposed small manufacturing facility
PEFI intends to build a 100 to 500 gallon/day proposed small manufacturing
facility in Raleigh, NC. This facility will be integrated with a four ton/day TRI
gasifier with the intention to gather data for scale up to a commercial size
facility.
Final design and construction of this small plant is expected to take nine to 12
months from funding. The plant will gasify MSW/RDF and is intended to
branch out to numerous other types of feedstock during its operations. The
overall objective of the facility is to gather data, build P&ID's and develop
economics of the entire system.

The design of the proposed demonstration manufacturing facility is very
similar to the Air Products/Eastman Chemical Liquid Phase Dimethyl Ether
("DME")/Methanol pilot plant (5,000 gallons/day) that was built at La Porte,
Texas. Eastman later built a chemicals-from-coal plant at commercial scale in
Kingsport, Tennessee (see Figure 2). This was an 80:1 scale-up in
capacity. This plant has operated successfully for over 22 years and is still
operating today.
The Air Products plant in La Porte, TX produced about 5,000 gal/day of
methanol (89% by weight) and DME (7% by weight) from syngas in a slurry
bubble column reactor (very similar to the PECI process) using a mixture of a
commercial methanol catalyst and a commercial dehydration
catalyst. Several demonstrations were completed from 1991 through 1999
(See Liquid Phase Dimethyl Ether Demonstration in the La Porte Alternative
Fuels Development Unit, DOE Topical Report prepared by Air Products and
Chemicals Inc., January 2001).
Following the initial pilot scale demonstrations, Air Products and Eastman
Chemical collaborated with the U.S. Department of Energy ("DOE") to build a
$213 million commercial scale plant in Tennessee to gasify coal and convert
the syngas to methanol in a larger slurry reactor. The DOE contributed $92
million to the project. Operations began on April 2, 1997 and nameplate
production capacity of 80,000 gallons per day was reached within four
days. Production rates exceeding 115% of the design level were achieved
within six days. During the 69-month demonstration program, the production
unit had an overall availability of 97.5%. (See Commercial Scale
Demonstration of the Liquid Phase Methanol Process, DOE Project Fact
Sheet (http://www.netl.doe.gov/cctc/ ).
