Downstream — Process Challenge

Selective H2S Removal in Gas Treating

In gas treating, H₂S must be selectively removed from CO₂-rich streams to meet pipeline specs. MDEA acts as a tertiary amine that preferentially absorbs H₂S over CO₂, enabling efficient acid gas removal.

Solution Approach

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, and H2S/CO2/water cut — and benchmark current treatment performance.
2
Chemistry Selection
Match scale and corrosion inhibitors, biocides, or demulsifiers to the operating envelope, factoring compatibility, regulatory constraints, and downstream impacts.
3
Field Trial & Dosing
Determine treat rates through bottle and field trials, and configure continuous or batch delivery and packaging (drums, totes, ISO tanks) to logistics.
4
Monitoring & Adjustment
Track corrosion coupon/ER rates, residual inhibitor, and separator and water-quality performance, adjusting chemistry and dose as wells change.
