Re: GAS-L: maximum pressure

["Dick Glick" <dglickd@pipeline.com>]

Hello --

In the mid-eighties, we had been scheduled to use a Canadian developed
gasifier, developed over the previous 15 years or so, by SNC -
Hydro-Quebec - Nouveler and operated at 10 atmospheres with a gas output at
1000 F and fed directly into the combustor of a Brown-Bavari gas turbine --
output of near 50 MW.  The gasifier was to be first used -- after
temperature reduction and washing of the output gas -- in a diesel electric
system in French Guiana.  The developer, SNC (now the largest Canadian
engineer firm) was to be paid for developing the conversion to cleaned gas
under contract with the French government -- We were told that the French
decided not to honor the SNC investment (?) -- after the gasifier had been
shipped to Guiana and tested -- SNC backed out of our agreement saying that
they could not go forward until they had been paid for their prior effort.
The B-B turbine was no longer produced -- and our project crashed.  We had a
PURPA 55 MW contract at the time, but our fate was shared by many holding
those contracts.

The primary difficult operating the gasifier was the pressurized lock-box
arrangement feeding the fuel into the gasifier.  That seemed to have been
reasonable perfected on a system -- operating at 10 tons per hour -- that
had been tested in Canada.
