摘要
介绍了废硫酸裂解制硫酸工艺技术路线,针对装置运行中存在的炉冷器炉管结焦堵塞和空气预热器堵灰等问题采取有效解决措施,提升了装置运行的稳定性,实现了废硫酸裂解再生装置长周期运行。
The technical route of waste sulphuric acid cracking to sulphuric acid is introduced.In view of the problems existing in the operation of the unit,such as blockage of the furnace tube of the furnace coolercaused by coking and ash blockage of the air preheater,effective measures are taken to improve the stability of the unit operation and realize the long-term operation of the waste sulphuric acid cracking regeneration unit.
