A dynamic model of the Shell gasifier in an integrated coal gasification combined cycle (IGCC) is established based on physical principles, focusing on the timedependent accumulation and flow on the walls. Numerical simulations are carried out to explore the system dynamic performance with respect to step changes in the inlet oxygentocoal ratio and steamtocoal.

Abstract. The Shell gasification process features a pressurised, slagging, entrainedflow reactor fed with dry, pulverised coal and oxygen. A 6 t/d pilot plant has been operating since 1976 in Amsterdam, and a 150 t/d plant has logged more than 6000 h at Harburg, West Germany. Both have used mainly European coals.

Coal gasification is an advanced conversion technology that converts solid fuel into clean syngas to be used for various energy and/or chemical production applications [1], [2], [3]. The integrated gasification combined cycle (IGCC) process is one of many applications for efficient electricity production with reduced environmental impact.
The Shell Coal Gasification Process (SCGP) was included in the EPRI evaluation of the more promising gasification technologies. To date, performance data for SCGP have been available mostly for European coals. This report evaluates the performance of an Illinois No. 5 coal in the SCGP. Tests were conducted in the process development unit (6 ...
Thermodynamic analysis of a gasification process was conducted assuming that it is composed of two successive stages, namely: pyrolysis reaction followed by a stage of gasification reaction. This approach allows formulation the models of selected gasification processes dominating in industrial applications namely: Shell (coal), SES (coal), and DFB (dual fluid bed, biomass) gasification.
The Shell Coal Gasification Process (SCGP) is a dry feed, entrained flow, oxygenblown, coal gasification process which has the capability of converting virtually any coal or solid hydrocarbon such as petroleum coke into a clean medium Btu synthesis gas, or syngas. The SCGP syngas is a mixture of predominantly carbon monoxide along with ...
A demonstrationunit of 250 MW e has been constructed in Buggenum, the Netherlands, based on the Shell Coal Gasification Process. The byproducts coal gasification slag and fly ash are formed in the gasifier reaction vessel and differ clearly from bottom ash and fly ash from pulverized coalfired boilers. This is due to the reducing conditions ...
A highly generalisable artificial neural network (ANN) model of excellent prediction accuracy (R 2 = and RMSE = ) has been developed to model the gasification of biomass and waste. The developed model is the first model able to predict gasification outputs over a wide range of feedstock, reactor, and gasifying agent options.
