Abstract
The invention is a process for separating acid gases from synthesis gas and treating the resulting solids. A mixture comprising synthesis gas and acid gas is contacted with a fluid that reacts with said acid gas to form a particulate solid dispersed in a fluid. The slurry comprising fluid and particulate solid is filtered to separate the particulate solid from the fluid by means of a regenerable filter. The particulate solids are removed from the regenerable filter by back-washing with a back-washing fluid to form a pumpable slurry comprising a mixture of particulate solids and back-washing fluid. The slurry is gasified to form synthesis gas and vitrified solids.
Claims11
A process for separating acid gases from synthesis gas comprising
- a) contacting a mixture comprising synthesis gas and acid gas with a fluid that reacts with said acid gas to form a particulate solid dispersed in a fluid and synthesis gas,
- b) separating the synthesis gas from a slurry comprising said fluid and said particulate solid,
- c) separating said particulate solid from said fluid by means of a regenerable filter,
- d) back-washing said particulate solid from said regenerable filter with a back-washing fluid to form a pumpable slurry comprising a mixture of particulate solids and back-washing fluid, and
- e) pumping said pumpable slurry to a gasification reactor wherein the slurry is gasified to form synthesis gas and vitrified solids.
