ソリューションアプローチ

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.

Hydroxyethylidene Diphosphonic Acid
CAS 2809-21-4
リン酸エステル・誘導体
Common phosphonate antiscalant
Threshold scale inhibitor that keeps carbonate/sulfate scale from forming in recycled hard process water
融点:198-199   沸点:578.8   Solubility: 1.15e+01 g/L

詳細情報
2-Hydroxyphosphonocarboxylic Acid (HPAA)
CAS 23783-26-8
リン酸エステル・誘導体
キレート化 / 金属イオン封鎖
Its defining, well-documented property is chlorine/oxidant tolerance, unlike ordinary phosphonates. That is exactly why it belongs on a recycled-process-water page where the water carries residual biocide/oxidant while still needing carbonate scale and carbon-steel corrosion control. Genuine, use-case-specific fit.
Physical Description: Brown liquid. Slight acrid odor

Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS)
CAS 40623-75-4
AA/AMPS copolymers are specifically valued for high calcium tolerance and stability at high hardness and temperature, dispersing CaCO3/sulfate and iron-oxide fines and keeping them suspended. These are precisely the reused/produced-water conditions, and it complements a threshold phosphonate. Genuine fit.

Bis(HexaMethylene Triamine Penta (Methylene Phosphonic Acid)) (BHMTPMPA)
CAS 34690-00-1
Premier low-dose inhibitor for barium/calcium sulfate scale. Sulfate scale (BaSO4/SrSO4) is the classic oilfield produced/recycle-water scaling problem that carbonate-focused inhibitors handle poorly, so this covers a distinct, on-topic failure mode rather than duplicating the carbonate chemistries. Genuine, distinctive fit.
