浓缩塔放空气的工艺设计

Process design of vent gas of concentration tower

由于变换气量及气体中硫含量的增加,导致原浓缩塔放空气中硫化氢质量浓度超标。通过增加浓缩副塔,解决原浓缩塔脱硫能力不足的问题。介绍了浓缩副塔的工艺计算和改进的工艺流程,改造后浓缩塔放空气中硫化氢质量浓度达到了设计要求。

The mass concentration of hydrogen sulfide in the vent gas of concentration tower is overproof due to the increase of shift gas quantity and sulfide compounds content. The shortage of sulfide compounds removing capacity is solved by adding a vice-concentration tower. The technical calculation of the vice-tower and the innovated technical process are presented, and the mass concentration of hydrogen sulfide in the vent gas reaches the design index after the innovation.
