摘要
将两个系列的76%硫酸洗净化中的一个改为绝热蒸发封闭稀酸洗净化。为了使新旧两系列能均衡生产,在新净化系列的间冷器出口和老净化系列的填料塔出口设置了混气包。新净化系列采用两级干燥一级吸收。改造后,改善了净化指标,全硫利用率由60%提高到7147%
One of the two 76% acid scrubbing systems was transformed to adopte adiabatical vapourization weak acid scrubbing technology.For balancing the capacity between the old and new systems,a gas mixing drum was installed downstream of indirect cooler for the new system and packed tower for the old one.The purification efficiency was improved and the total S utilization increased from 60% to 71.47% after transformation.
