Abstract
A disulfide oil hydrocarbon stream or a mixture of a disulfide oil hydrocarbon stream and a residual oil is partially oxidized in a gasifier to produce a hot raw synthesis gas containing hydrogen and carbon monoxide which can be passed to a steam generating heat exchanger to cool the hot raw synthesis gas and to produce steam which can be used to generate electricity via a turbine and, optionally, subjecting the cooled synthesis gas to the water/gas shift reaction to produce additional hydrogen and carbon dioxide.
Claims15
An integrated process for the treatment of a disulfide oil hydrocarbon stream comprises:
- a. introducing the disulfide oil hydrocarbon stream as a gasifier feed into a partial oxidation gasification reactor with a predetermined amount of oxygen and steam based on the carbon content of the disulfide oil hydrocarbon stream,
- wherein the disulfide oil hydrocarbon stream is an effluent refinery hydrocarbon stream recovered downstream of a MEROX process;
- b. subjecting the disulfide oil hydrocarbon stream to partial oxidation to produce a hot raw synthesis gas containing hydrogen and carbon monoxide;
- 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.
