Follow the broad route from resource to product. This is an introduction to the relationships, not an engineering flowsheet.
REFINE
Refining separates a feedstock into fractions. Different streams follow different processing routes, depending on the products required.
Distillation is a starting point, separating components by their boiling ranges. A refinery’s configuration determines the further processing available.
TRANSFORM
Conversion and treatment change selected streams into components for fuels and chemical feedstocks. Downstream processing connects those building blocks to materials.
Some processes change hydrocarbon molecules; others remove unwanted components or prepare a stream for the next stage. The whole route is designed around an agreed product requirement.
SUPPLY
Product identity, specification and delivery requirements come together in a commercial enquiry, connecting the material with its next use.
A live enquiry would confirm the application, required specification, supply format, quantity and delivery location. Supporting technical and safety documents would accompany a qualified product offer.
