Optimization of the ejector flashing regeneration in berfield carbon dioxide removal system

摘要

Based on the pinch analysis, the regeneration process in carbon dioxide removing system of a fertilizer plant is suitable to use thermal vapor recompression heat pump. To obtain economically optimal point, calculation and analysis have been done for the energy saving cost and economical benefit of each design with varying temperature drop of the potassium carbonate solutions. Moreover, the feasible energy saving plan and the type of the equipment are chosen according to the practical situation of the plant.
