Claim Text:
1. A gasification facility including: a gasifier; a high temperature gas cooler in fluid communication with the gasifier, the high temperature gas cooler being configured to receive and cool one or more gases generated at the gasifier, recover the heat produced by the cooling of the one or more gases and produce superheated steam using the recovered heat; two steam utilization devices in fluid communication with the high temperature gas cooler, the gas cooler delivering at least a portion of the superheated steam to the steam utilization devices, the steam utilization devices being operated by the superheated steam to provide respective outputs utilized within the gasification facility, a first of the steam utilization devices includes a steam turbine in fluid communication with the high temperature gas cooler and configured to generate electric power as an output using at least the portion of the superheated steam produced at the high temperature gas cooler, and an air separation unit separating oxygen from air and at least partially operated by the electrical power output from the stream turbine, the air separation unit being electrically connected to the steam turbine to receive the electric power from the steam turbine, a second of the steam utilization devices includes at least one compressor of the air separation unit, which is in fluid communication with the high temperature gas cooler and configured so as to receive and be driven by at the least a portion of the superheated steam, the air separation unit being operatively connected to the gasifier for provision of oxygen to the gasifier.
