Liquid Hydrocarbons: Refinery 'bottoms' via residue gasification
Liquid Hydrocarbons – Delivering bottom-of-the-barrel value
The market for fuel oil is shrinking, and many refineries are also under pressure to reduce plant emissions and meet product sulfur limits. Residue Gasification Technology is a clean, efficient, reliable and proven technology that can help address these pressures. When integrated with other upgrading and treating technologies, it can convert a wide range of low-value refinery residues and asphaltenes into syngas for:
- Integrated gasification combined-cycle power generation with optional carbon dioxide capture.
- Hydrogen production.
- Petrochemical production.
It also creates the opportunity to use heavier, less-expensive crudes and benefit from deeper conversion.

Delivering high efficiency and yield
Within the Residue Gasification Process system, hydrocarbon chains are partially oxidized in a refractory-lined reactor. This results in a high yield of syngas (carbon monoxide and hydrogen) and generates heat. The unit uses special burner and reactor designs to achieve high thermal efficiency and low soot levels. The syngas is cooled in an adjacent syngas effluent cooler, which produces high-pressure, saturated process steam that can help to lower plant operating costs.
Why select Residue Gasification Technology?
Unique and proven
Residue Gasification Process units use special burner and reactor designs backed by half a century of experience. Over 170 Residue Gasification Process reactors have been built and 96 are operating today.
Residue Gasification Process technology can process a wide range of feedstocks, including highly viscous, high-sulfur residues. Further benefits include:
- Low fresh water consumption
- Low soot formation (<1 mg/Nm³ of soot in raw syngas)
- Enhanced syngas yield (typically >2,600 Nm³ syngas per ton of feedstock)
- Enhanced thermal efficiency through the syngas cooling process (with high-pressure steam generation)
