Abstract

As an alternative to baseline technology a low-temperature syngas separation process has been proposed for pre-combustion CO2 capture from coal-derived syngas for an IGCC plant. Through systematic process synthesis – sequencing of separators and location of compressors and expanders, followed by Pinch Analysis and energy targeting – a process design has been proposed and the net power consumption has been estimated. From a targeted power consumption of 21.9 MW the figure for the proposed design is increased to 22.9 MW mainly due to increased load for auxiliary refrigeration at low temperature. The power consumption of the proposed design represents further improvement from earlier designs that have already been shown to have higher energy efficiency than baseline technology.
