摘要
近年来丙丁烷脱氢技术在中国得到推广应用,但因催化剂使用周期的限制,加之RED(产品气干燥器)干燥剂的长周期使用,致使干气压缩机结焦问题成为制约脱氢装置长周期安全稳定运行的重要因素。结合技工学校相关教材教学内容针对某脱氢装置装置干气压缩机结焦的问题采用特殊洗油的技术在原有装置上进行使用;实验结果表明通过使用该种洗油能够在催化剂使用后期满足干气压缩机长周期运行的需求,同时降低装置的安全风险。
With the application of propane dehydrogenation and butane dehydrogenation units in China,the coking problem of dry gas compressor has become an important factor restricting the safe and stable operation of dehydrogenation units in a long period,with the limitation of catalyst service life and the long period use of RED desiccants.In order to solve the coking problem of dry gas compressor in a dehydrogenation unit,special oil washing technology is used on the original unit.The experimental results show that the washing oil can meet the needs of the long period of dry gas compression and reduce the safety risk of the device.
