Gasification – converting the bottom of the barrel into valuable products

Traditionally, crude-oil residues have been sold as marine bunker fuel or used on-site as furnace fuel. However, with changing legislation, refineries are under pressure to reduce both their emissions and the sulphur content of their products; in addition, the market for fuel oil is shrinking.
The Shell gasification process can be combined with other upgrading and treating technologies to convert a wide range of low-value heavy residues and asphaltenes into synthesis gas (syngas). After treating, this gas can be used as clean fuel for high-efficiency combined-cycle power generation (with optional carbon dioxide capture); as a hydrogen source for hydrocrackers (combined with the water–gas shift reaction); or it can be converted into high-value products such as synthetic hydrocarbons.
By drawing on its experience, Shell Global Solutions provides business, operational-support and project-execution services from design and engineering* through to commissioning and start-up, experience transfer, master planning and training.
The Shell Group’s (“Shell”) experience in gasification dates back to the 1950s, and more than 100 Shell gasification units have been developed or are at the planning stage.
Have you considered how you can
· improve product quality while simultaneously reducing plant emissions?
· produce sufficient hydrogen for today’s clean fuels?
· adapt your processing facilities as demand for fuel oil diminishes?
