On-line delivery and operation optimization of blackwater settling system in coal to hydrogen plant
After the blackwater settling system of coal to hydrogen plant broke down,the grey water quality of the system deteriorated,which affected the smooth operation of the plant.For this reason,the settling system was switched and handed over online.The water circulation process of one coal to hydrogen plant was briefly described,the process optimization of the blackwater settling system,the optimization of the blackwater switching operation and the optimization of the settling tank emptying operation were introduced.In view of the problems of the valve sticking at the bottom of the vacuum flash tank,the increase of turbidity of the gasification grey water and the increase of the pressure difference of the quench water filter,the corresponding optimization measures were taken,ensuring the long-term stable operation of the gasifier.
