摘要
酸性气浓度低、量大，是硫回收装置操作困难的主要原因。气体脱硫装置将脱硫溶剂—乙醇胺更换为江苏宜兴市炼油助剂厂生产的YXS—93后，提高了酸性气中的H_2S浓度，降低了CO_2浓度，从而改善了酸性气质量，平稳了硫回收装置的生产，为开好硫磺回收装置创造了条件。
The main reason of difficult operation is the lowconcentration and large amount of sour gas in the sulfur recovery unit. The desulfurization solvent, ethanolamine,was changed to YXS-93 solvent that was produced by the refinery additive plant of Yixing city,Jiangsu. The H_2S concentration was increased and CO_2 concentration was decreased in sour gas. So the quality of sour gas was improved,the sulfur recovery unit runs smoothly and met the conditions for the sulfur recovery unit operation.
