摘要

Design of large scale air separation turbomachinery trains in the range of 50 MW to 80 MW are in increasing demand for use in air separation applications integrated with large scale process /industrial plant, including the following sectors: 1. Enhanced Oil Recovery (EOR): nitrogen injection schemes 2. Integrated Combined Cycle (IGCC) power schemes employing coal and refinery residues 3. Bulk methanol production schemes 4. Gas to Liquids (GTL) projects for stranded gas reserves In many instances steam is generated within the main process plant and the air separation plant power demand is integrated within the overall energy balance to optimise plant efficiency. The turbomachinery designer is faced with selecting machine designs which must handle large volume flows (air inlet volumes up to 1,300,000 m~2/h & steam exhaust volumes up to 1,600,000 m~3/h). Some limitations on train sizing are imposed by the maximum available shell and tube heat exchangers, the size of nozzles needed to introduce compressor intercooling and if necessary, steam reheat connections to limit the exhaust wetness. The paper describes how the turbomachinery design engineer, from both a compressor and steam turbine aspect, solves all the demands of the process energy balance, the physical size limitations and the dynamics of the coupled plant systems, into a machine train design that fully satisfies the demands from the major oil companies for referenced equipment.
