Upstream — Process Challenge

Demulsifiers for Crude Oil–Water Separation

Tight water-in-oil emulsions in production separators/treaters need targeted demulsifier chemistries
Why It Matters
Tight water-in-oil emulsions in production separators/treaters need targeted demulsifier chemistries
Solution Approach

Tight water-in-oil emulsions in production separators/treaters need targeted demulsifier chemistries RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (2)
EO/PO Block Copolymer (Demulsifier / Defoamer)
CAS 9003-11-6
Glycols & Polyols
Separation aid
The EO/PO block copolymer migrates to the oil-water interface and displaces the stabilizing asphaltene/resin film, letting water droplets coalesce and drop out
