2. Operating variables

The main operating variables that determine the gasification process are :

  • the nature of the hydrocarbon load;

  • oxygen/charge and water vapor/charge ratios;

  • pressure ;

  • the use of flame-temperature moderating gases other than water vapor, e.g. nitrogen (air gasification) or carbon dioxide.

2.1 Nature of hydrocarbon load

One of the features of the Shell process is that it can handle a wide variety of feedstocks: natural gas, naphtha, heavy fuel oil, vacuum distillation residue (VDR), visbreaking residue (thermal cracking of VDR) or asphalt obtained by solvent extraction (propane, butane or pentane) of...
