Feasibility Study of New Sulfur Oxide Control Processes for Application to Smelters and Power Plants. Part I: The Monsanto Cat-Ox Process for Application to Smelter Gases

摘要

An evaluation was made of the Cat-Ox process for the air pollution control of smelters. A block flow diagram was prepared. Mass and volume flow balances were estimated. Engineering estimates of the capital investment and the total annual cost (including both fixed and variable charges) were prepared. These engineering estimates were applied to previously created model gas streams and the total annual cost for each was determined. From these annual costs, incremental production costs were estimated. The technical constraints on the application and operation were qualitatively appraised; the economic constraints were appraised (quantitatively, to the extent permitted by the data). The current state of development was assessed, identifying any technological deficiencies whose elimination might enhance applicability. (Author)
