Shell Catalysts & Technologies’ Residue and Natural Gas Gasification process upgrades the bottom-of-the-barrel, other low-value streams, and waste into synthesis gas (carbon monoxide and hydrogen), for refinery consumption, power generation or use in other high-value processes.
Integrating the Shell Gasification Process with other upgrading and treating technologies enables you to process a wide range of feedstocks, including highly viscous, high-sulphur residues. The technology functions with low oxygen and fresh water consumption, resulting in low soot formation, and uses enhanced thermal efficiency that reduces operating costs while resulting in an enhanced syngas yield to supply the refinery with hydrogen, power or other usages.
An integrated Shell Gasification Process results in a high syngas (carbon monoxide and hydrogen) yield with low soot levels and high thermal efficiency that reduces plant emissions. Capture CO2 created during the process instead of releasing it into the environment, storing it for later processes, such as enhanced oil recovery, or for use in greenhouses.
Use the Shell Gasification Process to handle heavy high-sulphur viscous residues such as thermal cracked residue, Solvent de-Asphalter residue (DoA), the bottom streams of Ebullated bed units, and heavy fuel oil from the fluidised catalytic cracker (FCC) unit.
Refiners can use gasification to reduce operating costs through the production of high-pressure saturated process steam, while petrochemical companies can convert refinery residue to syngas for the production of ammonia, methanol, oxo-alcohols, and other petrochemicals to increase margins.
In the Shell 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.
Shell Gasification Process technology can process a wide range of feedstocks and waste, including highly viscous, high-sulphur residues. It also offers:
Through close partnerships with other users, Shell has the insight and experience to deliver.
The global Shell 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.
On-demand webinar: Plastic waste & biomass gasification for enabling the energy transition
Producing more circular, low-carbon and bio-based products and fuels from biomass and plastic waste streams is increasingly necessary for refiners and petrochemical companies.
Fortunately, if you have a gasification unit in your line-up, you can now process many waste plastic streams that other recycling options cannot, including un-sortable plastic waste.
Stream the webinar to see how innovative pre-conversion technology can help you maintain your competitive position through the energy transition.
