Abstract:

WSA wet acid making process is characterized by simple flow sheet, low operation cost, convenient operation and good environmental protection result and so on. The process has a very good adaptability for increasingly strict environmental laws and regulations. A general description is given to the process flow sheet and features of WSA acid making process of Haldor Topsoe in Denmark. Emphases are laid on the description of the relevant operation and control requirements needing attention in the production application. Meanwhile analysis and discussion are carried out in combination with the problems occurring in the commissioning and production of the acid making plant of Shao-steel Coking Plant.
