Gasification is a flexible and efficient process that produces mixtures of hydrogen and carbon monoxide (synthesis gas, or syngas) from carbon-based feedstocks such as petroleum coke, asphaltenes, vacuum residue, visbreaker tar and other petroleum residuals.
There are three basic components to gasification: air separation, gasification, and gas clean-up. Air separation produces the oxygen that is fed into the reactor with the carbon-based feedstock. In the case of coke, the feedstock is ground, mixed with water and fed in a slurry form into the gasifier, which operates under high temperatures and pressures to produce syngas. The ash and typical contaminants in the feedstock are consolidated into a marketable, vitrified slag material. The syngas is subsequently cooled and cleaned, including highly effective sulfur removal prior to use.
- Gasification in refineries can improve your operating margins by reducing or eliminating the need for natural gas to produce hydrogen, steam and power.
- Gasification offers the ability to convert these carbon-based residuals into N2, H2, steam and power in a petrochemical complex
- And gasification offers a proven commercial solution for carbon capture for use in enhanced oil recovery or for future emissions trading credits.
