Title:
INTEGRATION OF AN AIR SEPARATION APPARATUS AND OF A STEAM REHEATING CYCLE
Document Type and Number:
WIPO Patent Application WO/2009/103926
Kind Code:
A4
Abstract:
In a steam cycle work generating method, steam is expanded in a first turbine (T1), from a high pressure, generally above 50 bar, and a high temperature down to an intermediate pressure, the steam is reheated at the intermediate pressure without any substantial change in its pressure, the steam reheated at the intermediate pressure is then expanded in a second turbine (T2) down to a low pressure, typically a subatmospheric pressure, and a low temperature, and at least some of the throughput expanded in the second turbine is condensed, at least part of the condensed throughput is pressurized, at least part of the pressurized throughput is reheated to form a reheated throughput, at least part of the reheated throughput is sent to the first turbine and a fluid intended for or originating from an air separation apparatus is compressed in at least one compressor (C, BC) coupled to at least one of the first and second turbines.
