摘要
目前,国内炼油厂有些硫磺回收装置,由于生产不稳定而面临产生黑硫磺的问题,因而装置被迫停工,大量酸性气放入火炬焚烧,造成经济损失,并严重污染环境。本文分析了产生黑硫磺的原因,认为改进上游装置的设计和操作及提高环境保护意识,是避免硫磺回收装置产生黑硫磺的主要措施。
The sulfur recovery units in some domestic refineries are currently facing the problem of producing carbon black contuminated sulfur owing to unstable operation,which may some- times cause shut-down of the whole unit. As a consequence, large amount of acid gas are flared,causing economical losses and posing environmental pollution problems. This article,after analysing the origin of the catbon black contaminated sulfur,points out that improvements in design and operation of the up-stream units along with awareness on environment protection may serve as key measures to elimi- nate the problem of producing catbon black contaminated sulfur in sulfur recovery units.
