Abstract
A method and apparatus is described for reformulating of an input gas from a gasification reaction into a reformulated gas. More specifically, a gas reformulating system having a gas reformulating chamber, one or more plasma torches, one or more oxygen source(s) inputs and control system is provided thereby allowing for the conversion of an input gas from a gasification reaction into a gas of desired composition.
Claims20
A method for reformulating of an input gas from a low temperature gasification reaction into a carbon monoxide containing reformulated gas of a defined chemical composition, comprising the steps of
- (a) delivering the input gas from a low temperature gasifier to an inlet of a refractory-lined chamber;
- (b) injecting air and process additives into said chamber such that the input gas mixes with the air and process additives;
- (c) applying plasma heat from one or more plasma heat sources to the mixed input gas, air and process additives to promote dissociation of molecules therein;
- (d) allowing recombination of said dissociated molecules thereby producing reformulated gas;
- and
- (e) continually monitoring the composition of said reformulated gas produced in step (d) and, via feedback contra continually adjusting, in response to the monitored composition, (i) air and process additives injection rate in step (b) and (ii) the power to the one or more plasma heat sources, thereby producing said carbon monoxide containing reformulated gas of a defined chemical composition.
A method for converting an input gas from a low temperature gasification reaction into a product gas having a H2:CO ratio optimized for a downstream application, the method comprising the steps of:
- (a) applying plasma heat from one or more plasma heat sources to the input gas from a low temperature gasifier in the presence of air to dissociate molecules therein;
- (b) adding one or more process additives to the input gas;
- (c) allowing the dissociated molecules to recombine to provide a product gas;
- (d) imparting turbulence during steps (a), (b) and/or (c);
- (e) continually monitoring the H2:CO ratio of the product gas and continually comparing the H2:CO ratio of the product gas to a pre-determined range;
- and
- (f) in response to step (d) continually adjusting, via feedback control, (i) power to the one or more plasma sources, (ii) the amount of air of step (a) and (iii) the process additives of step (b) to produce product gas having a H2:CO ratio within the predetermined range.
