the chemical or physical separation methods used in coal

Physical separation method is more effective for high minerals containing feed coal, whereas, chemical separation method is more suited for low minerals containing feed coals. Chemical treatment processes is the most effective technique for removal of ash forming minerals from coal to produce UCC and have been extensively used [11] , [12] , [13 ...

An Introduction to CO2 Separation and Capture

2021-1-6  separation. The oxygen route does not. If the sinks are tolerant to NO x and SO 2, we can eliminate separate control steps and sequester the NO x and SO 2 along with the CO 2, resulting in a zero emissions power plant. Integrated coal gasification combined cycle (IGCC) plants are an example of the hydrogen route.
