Dynamic simulation of a Low-Temperature Rectification Column as Part of an IGCC Power Plant

摘要

IGCC(integrated gasification combined cycle)plants offer the opoportunity to utilize fossil energy osurces,like coal or heavy refinery residues,to satisfy increasing energy demand while considering strict environmental constraints[1].Such a plant consists of a combined power cycle,a fuel gasifier with downstream fuel gas conditioning and an air separation unit(ASU),where the oxygen required for gasification is produced.By using this concept efficiencies of up to 50% can be achieved.Compared to conventional coal-fired plants the use of an IGCC plant provides a considerable potential for CO_2 reduction.
