Assessment of a fully integrated SARGAS process operating on coal with near zero emissions

This paper presents a novel advanced clean-coal technology, Sargas that facilitates capture and storage of carbon dioxide (CCS). The technology combines the ABB Carbon P200 PFBC power cycle characterised by pressurised post-combustion acid gas cleaning. This article describes the conceptual idea and working principle of this technology, and provides some reference data for further assessment studies to be performed under two consecutive EU-based projects entitled EMINENT and EMIENT-2. For this survey process simulation data have been made available by technology owner, Sargas AS, for a coal-fired Sargas block rated at 100 MWe. The modelling and calculations have been performed by Sargas, using the HYSYS Mass and Energy Balance Model. The main results have been verified by a third party (Siemens). Recently the Finnish company SWECO PIC has developed the design basis for the first-of-its-kind coal-based Sargas plant planned for Husnes, Norway.
