Abstract:
1. A method to limit the deposition of metals, from a syngas stream generated by a gasifier, on a gas turbine, the method comprising the steps of: feeding the syngas stream from an acid gas removal process to a pressure swing adsorption vessel of a pressure swing adsorption system, wherein the syngas stream comprises carbonyls, the pressure swing adsorption vessel configured to perform a pressure swing adsorption cycle, the pressure swing adsorption cycle comprising the steps of: feeding the tail gas stream to an incinerator, the incinerator configured to oxidize the carbonyls in the tail gas stream to metal oxides and carbon dioxide; and feeding the turbine feed stream to the gas turbine, the turbine feed stream having a target carbonyl contamination.
