Abstract:

An introduction is given to the process flow, process features and key point control of AS gas desulphurization and the existing problems and ways for improvement are pointed out. In the process, the ammonia scrubbing of gas is combined with desulphurization and ammonia is used as heat source to make desulphurized solution regenerate and increase the free ammonia content in desulphuring lean solution. AS gas desulphurization process has higher desulphurization efficiency.
