<p>A turbine (150) produces in an improved gasification process a stream of pressurized air (156), which is cooled (180) and further compressed by a cooler and booster/compressor (190). The cooled and compressed air is humidified in a humidifier (130), heated by a low temperature heat source (134) and subsequently fed into a gasification vessel (110) in which a feedstock (120) is gasified or partially oxidized. The humidifier may advantageously utilize wastewater (170) to humidify the cooled and compressed air, wherein the wastewater may or may not be produced by a component in a gasification plant.</p> |
