Abstract: | The information contained in this paper is directed to engineering, production, and management individuals who will be concerned with the application of dry flue gas desulfurization technology to process and combustion sources. This paper describes such a system which is operating successfully on a petroleum coke calcining kiln. Acceptance tests and continuous data logging demonstrate sulfur dioxide removal efficiencies in excess of 90%, and participate emissions less than 0.005 gr/acf. The system consists of a spray dryer, fabric filter and auxiliaries which are designed to process up to 205,000 acfm gas flow. Continuing development work on system components has resulted in system availability exceeding 90%, while requiring an average of 4 man-hours per shift of operator supervision. A preventive maintenance program which includes routine operator inspections and data acquisition has served to reduce forced outages and maximize production. |
