Abstract
A process for producing an oxidized product in conjunction with a turbine for generating power. This process comprises contacting a compressed and heated oxygen-containing gas stream with at least one solid electrolyte oxygen selective ion transport membrane in a membrane reactor. A reactant is passed into the reactor to generate an oxidized product therefrom. Oxygen-depleted retentate stream from the reactor is added to a gas turbine combustor and expanded in a gas turbine to generate power.
Claims20
A process for producing an oxidized product in conjunction with a gas turbine system for generating power comprising the steps of:
- (a) contacting a compressed and heated oxygen-containing gas stream with at least one solid electrolyte oxygen ion transport membrane in a reactor, said reactor having a retentate zone and a permeate zone separated by said membrane, wherein at least a portion of oxygen is transported across said membrane from said retentate zone to said permeate zone to generate a permeate stream and an oxygen-depleted retentate stream;
- (b) passing a reactant into said permeate zone to react with said transported oxygen to generate an oxidized product therefrom;
- (c) adding said oxygen-depleted retentate stream to a gas turbine combustor;
- and
- (d) expanding in a gas turbine said combusted oxygen-depleted gas stream recovered from said gas turbine combustor, thereby generating power.
A process for producing substantially sulfur-free oxidized product gas in conjunction with a gas turbine for generating power comprising the steps of:
- (a) contacting a compressed and heated oxygen-containing gas stream with at least one solid electrolyte oxygen ion transport membrane in a reactor, said reactor having a retentate zone and a permeate zone separated by said membrane, wherein at least a portion of oxygen is transported across said membrane from said retentate zone to said permeate zone to generate a permeate stream and an oxygen-depleted retentate stream;
- (b) passing a reactant into said permeate zone to react with said transported oxygen to generate an oxidized product therefrom;
- (c) passing said oxidized product from step (b) into an acid gas remover to recover sulfur resulting in a substantially sulfur-free partially oxidized product;
- (d) adding said oxygen-depleted retentate stream in a gas turbine combustor;
- (e) combusting said sulfur-free partially oxidized product in said gas turbine combustor;
- and
- (f) expanding in a gas turbine expander said combusted oxygen-depleted gas stream recovered from a gas turbine combustor, thereby generating power.
