Description:
The report gives results of corrosion studies to provide definitive data concerning the corrosive nature of coke-oven waste-heat flue gas and its effects on wet electrostatic precipitators, and specifically on TRW's Charged Droplet Scrubber (CDS). The study characterized the chemical composition of the waste heat flue gases; related these data to corrosion and to the effects on the electrostatic scrubbing mechanism; evaluated materials compatibility with the coking process waste heat environment; and identified candidate agents which may be introduced into the waste heat gas stream to minimize the corrosive effects. It was determined that, with several equipment and operating modifications, projected life of the CDS casing and internals is 5 to 10 years, and life expectancy of the electrode nozzles is 1 to 2 years.
