A method to limit the deposition of metals from a syngas stream on a gas turbine comprising the steps of feeding the syngas stream to a pressure swing adsorption vessel of a pressure swing adsorption system, the syngas stream comprises carbonyls, the pressure swing adsorption vessel configured to perform a pressure swing adsorption cycle; adsorbing the carbonyls on a carbonyl selective adsorbent, leaving a turbine feed stream, reducing the pressure of the pressure swing adsorption vessel to a purge pressure less than the adsorbing pressure, purging the carbonyls from the carbonyl adsorbed adsorbent to create a tail gas stream, re-pressurizing the regenerated carbonyl adsorbent to the adsorbing pressure, feeding the tail gas stream to an 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. |
