The rebuilt by-products plant, and coal and coke material handling facilities began operation in Nov. 1992. Coal handling facilities were reused with repairs and modifications, such as new vibrating bin bottoms, bin blasters and variable-speed belts with weigh scales for an accurate coal blend. Coke handling consists of two new fixed-blade rack and pinion drive coke plows, new conveyors and screening station. The by-products plant processes 48 million cu ft of coke-oven gas per day through two rehabilitated primary coolers, one of two rehabilitated exhausters, two new tar precipitators in parallel, two new ammonia scrubbers with secondary cooling in series and two rehabilitated light oil scrubbers in series. Environmental facilities include ammonia stills, catalytic ammonia destruction reactors with waste heat boilers and complete gas blanketing for benzene control. All facilities are PLC and DCS controlled with data trending capability. The by-product plant met all performance guarantees without any problems.
