A S Jessup-Bould: Gasification and Pyrolysis Experience |
||
Over the years I have undertaken process design work for many
gasification plant proposals, including pyrolysis plant. Until now, the economics
of many projects investigated have prevented them from becoming realised.
Despite this, I have not been without practical experience of their
operation, including co-ordination of oxygen blown trials on a full size coke
gasifier which was one of my most rewarding engineering experiences. I have
also worked briefly as a support operator during trials of the, semi-commercial
size, CRE (Coal Research Establishment) fluidised bed coal gasification pilot
plant.
I have also had the benefit of feedback from the operation of pyrolysis
units working on sewage sludge and wood.
More recently I have worked on projects for the sub-stoichiometric
combustion of municipal and hazardous wastes using multiple batch filled
chambers configured for sequential operation, thus replicating continuous
operation. This has included co-ordination of trials and gas sampling for
mass-balance determination on a demonstration plant.
