The market for fuel oil is shrinking. Many refineries are also under pressure to reduce plant emissions and meet product sulphur limits.

The Residue Gasification Process is a clean, efficient, reliable and proven technology. 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 via water–gas shift; and
  • Petrochemical production.

It also creates the opportunity to use heavier, less expensive crudes and benefit from deeper conversion.

Strategic Alliance with Air Products

Shell and Air Products have agreed a global Strategic Alliance to jointly develop and commercialize Residue Gasification Technology.

The alliance includes the sharing of patent rights and also comprise co-ordinated scouting, development and commercialization of opportunities for deployment of the technology. This offers the opportunity to share and leverage Shell’s strong technology offering and refining experiences with Air Products’ Build-Own-Operate option, strengthening the total value proposition for customers.

Delivering high efficiency and yield. In the Residue Gasification Process, hydrocarbon chains are partially oxidised in a refractory-lined reactor. This results in a high syngas (carbon monoxide and hydrogen) yield 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 Process technology?

  • It is unique and proven. Residue Gasification Process units use special burner and reactor designs and are the products of half a century of experience. Over 170 Residue Gasification reactors have been built and 96 are operating today.
  • It works. Residue Gasification Process technology can process a wide range of feedstocks, including highly viscous, high-sulphur residues. It also offers:
    • Low oxygen and fresh water consumption;
    • Low soot formation (<1 mg/Nm³ of soot in raw syngas);
    • Enhanced syngas yield (typically >2,600 Nm³ syngas per tonne of feedstock); and
    • Enhanced thermal efficiency through the syngas cooling process (with high-pressure steam generation).
  • It keeps getting better. As an owner and operator, and through close partnerships with other users, Shell has the insight and experience to deliver. We record innovations and improvements in a lessons-learned database for the benefit of all licensees and to improve our master design. Focusing on continuous improvement through innovation and partnership helps us to achieve longer continuous runs and lower maintenance costs.
  • It is supported. Our global Residue Gasification Process technical service centre provides dedicated life-cycle support for lifetime assurance, including design, simulation, start-up assistance and training, and long-term operational assistance. We facilitate global technology-user conferences that aim to build user communities and accelerate learning.
