Comparing Capacity Expansion and Waste Minimization Options at a Chemical Manufacturing Facility
Abstract:Industrial wastewater treatment facilities that are nearing their capacity limit often have a relief option that typically is not available to municipal treatment facilities. That option is to reduce waste loads coming from the production areas by optimizing manufacturing processes so that less waste is generated per pound of product made. In making the decision between reducing waste loads and increasing treatment capacity, the facility owners need to identify and thoroughly assess each performance limiting unit process and then determine the capital and operating costs of adding the next increment of capacity. The net present cost of the expansion option (expressed as cost per quantity of capacity added) is then used as the standard against which the waste minimization options are evaluated. This paper presents a case study where this approach was applied at a large chemical manufacturing facility.
