Abstract
A turbine produces in an improved gasification process a stream of pressurized air, which is cooled and further compressed by a cooler and booster/compressor. The cooled and compressed air is humidified in a humidifier, heated by a low temperature heat source and subsequently fed into a gasification vessel in which a feedstock is gasified or partially oxidized. The humidifier may advantageously utilize wastewater to humidify the cooled and compressed air, wherein the wastewater may or may not be produced by a component in a gasification plant.
Claims20
A plant, comprising:
- a turbine that produces a stream of pressurized air, and a cooler coupled to the turbine such that the cooler receives and cools the stream of pressurized air to produce a stream of cooled pressurized air;
- a booster fluidly coupled to the turbine such that the booster receives and further compresses the stream of cooled pressurized air to produce a stream of cooled compressed air;
- a humidifier fluidly coupled to the booster, wherein the humidifier receives and humidifies the stream of cooled compressed air to produce a stream of humidified compressed air, and a heater operationally coupled to the humidifier such that the heater receives and heats the stream of humidified compressed air to produce a stream of heated humidified air;
- and
- a gasification vessel fluidly coupled to the humidifier such that the gasification vessel receives at least part of the stream of heated humidified air.
