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) 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 ...
Obtaining the temperature inside the gasifier of a Shell coal gasification process (SCGP) in realtime is very important for safe process operation. However, this temperature cannot be measured directly due to the harsh operating condition. Estimating this temperature using the extended Kalman filter (EKF) based on a simplified mechanistic ...

The gas composition affects investment of the coal to hydrogen process and CO 2 emission [8]. There are three main types of gasifiers: fixed bed gasifier, entrained flow gasifier [9] and fluidized bed gasifier [10]. As one of the entrained flow gasifiers, the Shell gasifier has been applied in the coal to hydrogen process.
Computational fluid dynamics (CFD) modeling of cogasification is conducted using a validated gasification model to examine the effect of biomass amount on the cogasification process in a Shell gasifier. In the submodels for coal and biomass char reactions, pore and bulk diffusions are considered using a userdefined function. The coal ...
Major recent projects based on the SGPtechnology are the PER+ project at Shell Pernis refinery and the Shell Middle Distillate Synthesis Process (SMDS). The SCGP technology has recently been applied in the 250 MWe Integrated Coal Gasification Combined Cycle at Demkolec, Buggenum. These processes and projects are described here. 5 figs., 3 tabs.
SCGP process General In the early 70's Shell decided to start the development of a coal gasification process building upon the technology base of pressurised oil gasification. Against the background of the potential applications (power production, chemicals, town gas, synthetic natural gas and transportation fuels) and the
It is one of the most expensive items in a coal gasification system. Fouling on heat surface can decrease the heat transfer and threaten the reactor operation. The serious slag deposition problem in Shell syngas cooler has been reported in China and is still unsolved [6]. Therefore, understanding slag behaviors inside syngas cooler is as ...
An integrated Shell Gasification Process results in a high syngas (carbon monoxide and hydrogen) yield with low soot levels and high thermal efficiency that reduces plant emissions. Capture CO 2 created during the process instead of releasing it into the environment, storing it for later processes, such as enhanced oil recovery, or for use in ...
