ABSTRACT:
An integrated polygeneration system and process is disclosed for generating liquid hydrogen as a main energy product for use as a propellant for space vehicles. Secondary energy products and commodities for supporting a space center complex and launching of the space vehicle includes the production of electrical and thermal energy and gaseous nitrogen. The integrated process includes a coal gasification and gas cleanup system (12), a combined cycle power generation system (18), a hydrogen production and liquefaction system (22) and a air separation system (32). A medium BTU gas (16) is produced by the coal gasification system and is delivered at (16a) to the power generation system and (16b) the hydrogen production and liquefaction system. Steam (14) also produced in the coal gasification process is delivered to a steam turbine in the combined cycle power generation system which is combined with a gas turbine to which the medium BTU gas is delivered to generate electrical and thermal power in a combined cycle power generation process. Steam from the coal gasification process is also delivered to a shift conversion unit in the hydrogen production system to increase the hydrogen content of the medium BTU gas prior to liquification. Air separation system (32) produces oxygen and gaseous nitrogen. The oxygen is utilized in the coal gasification process and the gaseous nitrogen is delivered for storage to a launch complex site where it is used as an inert gas to purge critical environments. The gaseous nitrogen is also utilized in the hydrogen production system where the nitrogen is liquified and used to refrigerate the hydrogen.
