氨硫洗涤流程氨水除油工艺改进建议

Improvements on AS Process for Ammonia Liquid Uncoiling Technology

介绍了离心式气浮除油技术 ,运用该技术可使焦化剩余氨水、富氨水含油量减少至 2 0 mg/ L ,使换热器、脱硫塔等设备堵塞的次数降低 90 % ,达到生产工艺的良好循环和连续稳定 ,净化煤气合格率 99%以上。

The centrifugal gas adsorption uncoiling technology is introduced in this paper. By using this technology, the oil content in the residual ammonia liquid from coking and oil content in the ammonia rich liquid are all reduced to 20mg/L, the blockage times of the heat exchanger, washing tower and the dusulfurization tower decrease by 90 %, and the whole process can run into a good circle.
