Patent ID: 8562933

Claim:
A hot solids process selectively operable for purposes of generating at least one predetermined output, based on what the specific nature of the primary purpose of the hot solids process is for which the at least one predetermined output is being produced, comprising: pre-selecting a primary purpose of the hot solids process from a group of primary purposes of the hot solids process, which includes at least two members selected from the group consisting of the generation of a feedstock such as H 2 for use for purposes of electric power production, the generation of syngas for use for purposes of electric power production as well as for other industrial uses, production of steam for electric power generation as well as for other uses, production of process heat, the production of CO 2 for agricultural purposes, and the generation of H 2 for use for the production of liquid hydrocarbons; providing a first reactor capable of being operated as a reducing reactor; providing a second reactor capable of being operated as an oxidizing reactor; supplying as inputs to the reducing reactor both a sulfur containing solid carbonaceous fuel and a source of calcium; supplying air as an input to the oxidizing reactor; effecting in the reducing reactor with the source of calcium the capture of the sulfur in the sulfur containing solid carbonaceous fuel to thereby produce CaS in the reducing reactor; effecting the discharge of the CaS as an output from the reducing reactor and then supplying such CaS as an input to the oxidizing reactor; effecting in the oxidizing reactor the production of CaSO 4 from the CaS that is supplied as an input to the oxidizing reactor; supply feedwater to the oxidizing reactor; where the feedwater is converted to steam for electrical power generation; effecting the discharge of the CaSO 4 that is produced in the oxidizing reactor as an output from the oxidizing reactor and then supplying such CaSO 4 as an input to the reducing reactor; selectively generating at least one predetermined output based on what the specific nature of the primary purpose of the hot solids process is for which the at least one predetermined output is being produced from the performance of one of the following wherein CaSO 4 is utilized in the reducing reactor both as an oxygen source and as a heat source in order to thereby effect the generation in the reducing reactor of the at least one predetermined output from the sulfur containing solid carbonaceous fuel and wherein CaS is burned in a heat liberating reaction in the oxidizing reactor to effect the generation of the at least one predetermined output in the oxidizing reactor from the heat liberated during the burning of the CaS in the oxidizing reactor; and effecting the discharge of the at least one predetermined output that is selectively generated in one of the reducing reactor and oxidizing reactor.
