The Shell Coal Gasification Process (SCGP) is in the forefront of coal gasification technology. Wide experience was gained with development (Shell Amsterdam Laboratory), pilot (Deutsche Shell, Harburg refinery) and demonstration units (SCGP1, Houston, USA). SCGP flexibility has been demonstrated for feeds ranging from bituminous coals to ...
The Shell Blue Hydrogen Process offers significant advantages over alternative technologies, which include steam methane reforming (SMR) and autothermal reforming (ATR). For example, compared with SMR, it saves money by maximising carboncapture efficiency and simplifying the process lineup, which offsets the oxygen production costs.
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 ...
Coal gasification is one of the most important clean coal technologies, and the Shell coal gasification process (SCGP) is a popular coal gasification process. SCGP has advantages including large scales, high carbon conversion, and high cold gas efficiency over many other coal gasification processes [2]. If SCGP can achieve stable operation for ...

Juliana has 12 years of commercial experience in licensing and business development of Shell's dry feed gasification and Cansolv® process technology (desulfurisation and CO2 capture). She was accountable for licensing customers in the oil gas ...
Comparison between the properties of two coal samples, as well as, the properties of syngas produced from these coal samples by Shell coal gasification technology is summarized in Table 2. From Table 2 it seems that the amount of ash in feedstock affects syngas composition, heating value and cold gas efficiency.

The Shell Coal Gasification Process (SCGP) uses an upflow, entrained flow gasifier operating on a dry feed at slagging temperatures (Fig. ). The upflow arrangement allows separation of syngas and slag largely within the reactor itself. Typically there are four sidemounted burners located in the lower part of the reactor.
The Shell coal gasification process (SCGP) can operate on a wide variety of feedstocks. It consists of three principal stages: 1. Gasification (partial oxidation), in which the feedstock is converted to syngas in the presence of oxygen and a moderating agent (steam) in a refractorylined gasification reactor. 2.
Shell Gasification Process (Kamble, et al., 2019) ... Gasification of coal in a bath of molten sodium carbonate through which steam is passed is the basis of the Kellogg Coal Gasification process ...
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.
