Crude oil flow
Pour-point-depressant and flow-improver selection for wax-containing crude oils.
How it is used
Polymeric flow improvers modify wax crystallisation in crude oil. Changing the crystal structure can limit the formation of an interlocking wax network and help maintain flow at lower temperatures. The response varies with crude composition and thermal history.
Application areas
- Crude-oil gathering and transfer
- Storage and handling of waxy crude
- Low-temperature flow assurance
Formulation considerations
Candidate polymer families include acrylates, polymethacrylates, maleate/fumarate polymers, vinyl-acetate copolymers and alpha-olefin copolymers. Laboratory screening determines the suitable grade.
What we need to select a grade
- Crude sample, wax content and baseline pour point
- Cooling history and operating-temperature range
- Viscosity or flow targets and the proposed injection point
Product data and handling
Request the current technical data sheet and safety data sheet for the proposed grade. Confirm dosage, compatibility, handling and supply requirements before use.
This page concerns crude-oil applications. Diesel cold-flow improvers are a separate application and must not be substituted without evaluation.
