AM-08-48 Stoichiometic Combustion Control for Reducing CO2 Emissions

Description:

There are a number of methods to mitigate emissions that result from refinery combustion processes. They typically involve the addition of expensive hardware, the magnitude of which depends on the reductions that need to be achieved. However, if the combustion process produces the lowest emissions possible before leaving the stack, emissions creation can be minimized. Operating refinery heaters and boilers at the most efficient combustion possible will result in the lowest emissions from the start. Stoichiometric is considered the theoretically ideal combustion condition where all the fuel is consumed with no unburned components and no excess air leaving the combustion chamber. We will examine a practical combustion control system that results in achieving and maintaining a near stoichiometric condition. Included will be a listing of the necessary ingredients required, the resultant improved safety and additional benefits derived from such a Stoichiometric Combustion Control System. This paper will discuss the implementation of Stoichiometric Combustion Control on 7 installations at the Big West of California, Flying J refinery in Bakersfield, California.
