加氢裂化原料采用氮气保护,减少与空气中的氧接触,对其质量保护有一定的效果. 设计使用的氮封保护系统是采用自力式减压稳压调节系统.为减少氮气消耗,油缸顶部设置了压力平衡管,将油罐两两串联,氮气使用随生产操作的 Hydrocracking raw materials using nitrogen to reduce oxygen contact with the air, the quality of its protection to a certain extent.The design of the nitrogen seal protection system is the use of self-Regulated Regulator system.In order to reduce nitrogen consumption, the top of the cylinder Set pressure balance pipe, the tank in series between the two, nitrogen use with the production operation
