Abstract
An integrated process for the partial oxidation of whole crude oil mixed with a low cost finely divided solid ash-producing material in a membrane wall gasification reactor produces a syngas and, optionally, a more hydrogen-rich product stream by subjecting the syngas to a water-gas shift reaction. Process steam and electricity are produced by recovering the sensible heat values from the hot syngas.
Claims15
An integrated process for the gasification of a whole crude oil feedstock to produce a synthesis gas and electricity, the process comprising:
- a. introducing as a feedstock, whole crude oil and a solid ash-producing material into a membrane wall gasification reactor with a predetermined amount of oxygen and steam based on the carbon content of the feedstock;
- b. subjecting the whole crude oil to partial oxidation to produce hydrogen and carbon monoxide in the form of a hot raw synthesis gas;
- c. passing the hot raw synthesis gas to a steam-generating heat exchanger to cool the hot raw synthesis gas and to produce steam;
- d. introducing the steam from the heat exchanger into a turbine to produce electricity;
- and
- e. recovering the cooled synthesis gas.
The method of claims 3-8, wherein the hydrogen content of the light fraction is in the range of from 12 to 16 w %.
