Flue Gas Desulfurization Calculating Gypsum Produced from Coal Bunkered

Stoichiometric Calculation of Gypsum from Coal Bunkered

This is a sample calculation that shows how to calculate the gypsum produced from a scrubber using the amount of coal consumed and stoichiometry.

Double Loop Wet Limestone Scrubber Chemistry Control

This article is written to operators to provide information on the chemistry control of a double loop scrubber.  This article covers normal operation of the double loop scrubbers and does not address special circumstances such as aluminum fluoride blinding and particle size crashes.
I operated double loop scrubbers with a quencher capacity of approximately 60,000 gallons and an absorber feed tank of approximately 180,000 gallons.  The diameter of the tower was 36 feet.

How is the Flue Gas Scrubbed in a Double Loop Scrubber?

This article describes how the flue gas moves through a double loop scrubber and what happens to the gas as it moves through the scrubber.  Some of the functions of the scrubber internals are also described.  

Wet Limestone Scrubbers.

I will be posting some information for whoever can use it.  It is the knowledge I gained in operating four double loop scrubbers and one single loop scrubber.

I worked as an operations engineer for six years at a electrical utility in Tampa, Florida.  During the time that I worked there, I was able to operate five wet limestone scrubbers.

I worked closely with the operators and the lab to optimize the operations of these scrubbers.  I will be posting blogs concerning how I operated the scrubbers. May be someone out there might need this information.
