[Gasification] 2 MWe Gasifier at University of British Columbia, Vancouver, Canada

[Tom Miles]

>Hi Tom,

>This looks very interesting project. Can you please share project report or
any details of configuration? What have you been thinking for gas clean up
and tar >elimination?

 

I can't say more than what they have presented to the public. Some of the
details are "patent pending."

 

Look at slide 3 of their UBC project profile:

You'll see that they:

1.       take the low temperature gas from the gasifier, 

2.      heat it with waste heat from cracked gas, 

3.      burn the heated gas enough to reduce tars through partial oxidation,

4.      cool the gas,

5.      filter it,

6.      then they cool and condense the gas before going to the engine.

 

These are steps they have developed over the last several years for various
industrial heat applications, and at 250 kWe at their pilot plant for 3,000
hours. They appear to have met their targets for gas cleaning. At the
Pacific West Biomass Meeting in San Francisco in January they showed photos
of their engine and oil inspection data for the 250 kWe genset after 2814
hours.   

 

The engineer responsible for the operation of their engine at UBC has
significant experience with GE Jenbacher engines for a variety of fuels and
applications. He is absolutely confident about the cleanliness of the gas
and the expected low maintenance on the engine. 

 

"Seeing is believing" in this business so we will soon find out. The system
just has to run, and run, and run. . .
