Benefit Analysis and FGD Optimization for Designed Power Plant Based on Comprehensive Benefit Index System

Abstract:

Taking the initial design value for target power plant as standard index values, two comprehensive benefit index systems for flue gas desulphurization (FGD) technology were formed by mean square difference method with or without the index of earning of by-product, to analyze the environmental benefit, economic benefit, technology benefit and comprehensive benefit of six flue gas desulphurization technologies on designed power plant and obtained the optimal technology ultimately. For the index system with index of earning of by-product, the optimal FGD technology is wet ammonia desulphurization, not only possesses the biggest comprehensive benefit, but also the biggest economical and technology benefit for designed power plant. For the index system without the index of earning of by-product, the wet ammonia desulphurization, limestone wet desulfurization and simple wet desulfurization have similar comprehensive benefits, but individual advantage on environmental, economic and technology benefit separately.
