FEASIBILITY STUDY OF GAS TREATMENT PLANT BASED ON AN EJECTOR SCRUBBER

Abstract

Summary. The article executed the feasibility study of various options for gas treatment. Rapid development of industry and transport worldwide in recent times raises the problem in the protection of habitat environment from harmful waste. In solving problems of flue gas treatment great attention is given to the economic characteristics and recycling techniques for capturing emissions and disposal must also meet the sanitary health requirements: flue gas treatment plants should not cause air or water pollution. The set objective is solved by developing a two-stage wet treatment system for pyrolysis gas based on ejector scrubbers. Their advantage - a central nozzle supply that allows the scrubber to operate on the principle of an ejector pump. Projected plant can be used in enterprises for processing of solid domestic and industrial waste, where there are steam and hot water boilers, whose operations result in contaminated gases emissions obtained with high temperatures. In particular, this installation can be applied at a cement plant in which a large amount of waste gases containing sulfur oxides is emitted. Assessment of market potential for the plant designed to treat waste gases in the cement factory is performed through a SWOT analysis. SWOT analysis results indicate the possibility of the treatment of exhaust gases without a high cost and with high gas treatment efficiency. Plant competitive analysis was done using an expert method in comparison with market competitors. Technical and economic indicators of the plant are presented. Return on investments is 46% and payback period of capital investments - 2.7 years.
