Abstract

Coal-based Allam cycle, an efficient oxy-fuel combustion semi-closed supercritical carbon dioxide (sCO2) cycle coupled to coal gasification, can realize the zero carbon emission to the atmosphere. The aim of this study is to develop a new process splitting analytical method to clearly illustrate the energy conversion performance of the complex system and guide the process integration for efficiency improvement. Based on the new analytical method, the basic coal-based Allam cycle is split into four parts, including a closed sCO2 cycle, a closed steam Rankine cycle, open process and air separation unit (ASU). Then, the process splitting analytical models are constructed and the process integration is carried out in three aspects: the heat integration of ASU, the steam extraction for pre-drying and gasification, and the integration of sCO2 cycle for heat recovery of raw syngas. Finally, the net efficiency of the modified coal-based Allam cycle is improved to 42.48% using the new process splitting analytical method, which is 3.68% points higher than that of the basic configuration. The developed process splitting analytical method might give a new perspective to evaluate the energy conversion performance of the complex coal-based semi-closed power cycle in a clear and simple way.
