Abstract
A process for process for generating power in an ammonia-fueled gas turbine power plant includes flowing an ammonia feed stream to an ammonia cracker reactor in geographical proximity to an ammonia-fueled gas turbine power plant to crack ammonia feed stream under cracking conditions, thereby producing a product effluent comprising ammonia and hydrogen, flowing the product effluent comprising ammonia and hydrogen to an ammonia-fueled gas turbine of an ammonia-fueled gas turbine power plant, and combusting the product effluent comprising ammonia and hydrogen to drive the ammonia-fueled gas turbine. An exhaust gas stream generated from the ammonia-fueled gas turbine is recycled back to supply heat to the ammonia cracker reactor.

A process for generating power in an ammonia-fueled gas turbine power plant, comprising:
- flowing an ammonia feed stream to an ammonia cracker reactor in geographical proximity to an ammonia-fueled gas turbine power plant to crack ammonia feed stream under cracking conditions, thereby producing a product effluent comprising ammonia and hydrogen;
- flowing the product effluent comprising ammonia and hydrogen to an ammonia-fueled gas turbine of an ammonia-fueled gas turbine power plant;
- and
- combusting the product effluent comprising ammonia and hydrogen to drive the ammonia-fueled gas turbine;
- wherein an exhaust stream generated from the ammonia-fueled gas turbine is recycled back to supply heat to the ammonia cracker reactor.
A process for generating power in an ammonia-fueled gas turbine power plant, comprising:
- flowing an ammonia gas feed stream to an ammonia cracker reactor in geographical proximity to an ammonia-fueled gas turbine power plant to crack ammonia feed stream under cracking conditions, thereby producing a product effluent comprising ammonia and hydrogen;
- flowing a liquid ammonia feed stream to a vaporizer to produce a vapor comprising ammonia gas;
- introducing the product effluent comprising ammonia and hydrogen into a water wash column, thereby producing a hydrogen-enriched gas effluent and an ammonia-enriched effluent comprising ammonia and water;
- introducing the ammonia-enriched effluent into a distillation column, thereby producing a cleaned water wash stream and an ammonia gas;
- introducing the hydrogen-enriched effluent to a pressure swing adsorption unit, thereby producing a high-purity hydrogen gas;
- combining the vapor comprising ammonia gas, the ammonia gas and the high-purity hydrogen gas, thereby producing a product gas comprising from about 50 vol. % to about 75 vol. % ammonia gas and from about 25 vol. % to about 50 vol. % high-purity hydrogen gas;
- and
- combusting the product gas in an ammonia-fueled gas turbine to drive the ammonia-fueled gas turbine for providing power to the ammonia-fueled gas turbine power plant.
A system, comprising:
- an ammonia cracker reactor in geographical proximity to an ammonia-fueled gas turbine power plant configured to crack an ammonia feed stream under cracking conditions, thereby producing a product effluent comprising ammonia and hydrogen;
- an ammonia-fueled gas turbine comprising a compressor, a combustor and a turbine of the ammonia-fueled gas turbine power plant and configured to combust the product effluent comprising ammonia and hydrogen and drive the ammonia-fueled gas turbine;
- and
- a recycle line configured to flow an exhaust gas stream generated from the ammonia-fueled gas turbine back to supply heat to the ammonia cracker reactor.
