Equilibrium Simulations of Coal Gasification – Factors Affecting Syngas Composition

Storing syngas lowers the carbon price for profitable coal gasification.

Integrated gasification combined cycle (IGCC) electric power generation systems with carbon capture and sequestration have desirable environmental qualities but are not profitable when the carbon dioxide price is less than approximately $50 per metric ton. We examine whether an IGCC facility that operates its gasifier continuously butstores the syngas and produces electricity only when daily pr...

Factors Affecting Dustcake Drag in a Hot-gas Filter System Collecting Coal Gasification Ash

This paper discusses the use of laboratory drag measurements and filter operating data to analyze factors affecting dustcake flow resistance in a hot-gas filter at the Power Systems Development Facility (PSDF). The hot-gas filter is a Siemens-Westinghouse two-tier candle filter system that is collecting coal gasification ash from a KBR Transport Gasifier. Operating experience with this system h...

Gasification, Producer Gas and Syngas - FSA1051

Gasification involves turning organic fuels (such as biomass resources) into gaseous compounds (producer gas or syngas) by supplying less oxygen than is needed for com­ plete combustion of the fuel. Gasifica­ tion occurs at temperatures between 1112o and 2732o F and produces a lowto medium-energy gas depending upon the process type and operating conditions. Gasification of biomass resources is ...
