摘要
介绍炼厂酸性气制硫酸装置的工艺过程。由于实供气源与设计值有较大出入,二氧化碳浓度偏高, 并且夹带烃类物质较多,使装置无法正常运行。通过对酸性气进行预处理后,一次开车成功,各项工艺指标均达到设计要求,遇酸性气流量突降时可补充适量硫磺,维持正常生产。
Process of sulphuric acid production from refinery acid gas is described. After initial startup, the plant couldn＇t operate smoothly because acid gas supply deviated greatly from design values, besides, with too much carbon dioxide and hydrocarbon carry-over. By installation of acid gas pre-treatment equipment, the plant operated well with all process indexes up to design requirement. If acid gas flow suddenly dropped, appropriate amount of sulphur was supplied to keep normal production.
