Feasibility Study of New Sulfur Oxide Control Processes for Application to Smelters and Power Plants. Part II: The Wellman-Lord SO2 Recovery Process for Application to Smelter Gases

摘要

Discussed is the evaluation of the Wellman-Lord SO2 process for the control of SO2 from 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)
