Lime and limestone wet

Lime and Limestone Wet Scrubbing. The problem of atmospheric pollution by sulfur oxides has been given extensive attention by research and development firms in recent years and several process types are being proposed for full scale application. Lime and limestone wet scrubbing appears to be the most promising approach for immediate application. The major diflSculty with the limestone or lime systems is solid deposition in the absorption device which could create unreliability and unscheduled shutdowns for the power plant. 

This report describes the results of the Shawnee Lime and Limestone Wet Scrubbing Test Program conducted by EPA s Industrial Environmental Research Laboratory, Research Triangle Park, North Carolina (IERL-RTP). In this program, flue gas desulfurization (FGD) tests were conducted at the EPA 10 MW prototype Shawnee Test Facility located at the Tennessee Valley Authority (TVA) coal-fired Shawnee Power Station near Paducah, Kentucky. Bechtel Group, Inc. of San Francisco was the major contractor and test director, and TVA was the constructor and facility operator. Results of the program before July 1978 have been reported elsewhere (1.2) ... 

A primary objective of the EPA alkali wet scrubbing test program during the last several years has been to enhance SO2 removal and improve the reliability and economics of lime and limestone wet scrubbing systems by use of adipic acid as a chemical additive.
