Crude Oil Demulsifier Chemical | Beta Pramesti Asia
BETAFLOW crude oil demulsifier chemical for oil-water separation. Review bottle test, dose, injection point, BS&W, interface, and program cost onsite.
Crude oil demulsifier chemical breaks oil-water emulsions
A crude oil demulsifier chemical helps break emulsions so water separates faster, the interface becomes sharper, and oil BS&W can be controlled. PT Beta Pramesti Asia selects BETAFLOW DM from fluid samples, temperature, residence time, mixing pattern, injection point, oil and water quality targets, and test results—not from a catalogue dose alone.
BETAFLOW DM 201 is published as a demulsifier for reducing water and sediment in crude oil, while BETAFLOW DM 222 breaks emulsions and helps reduce fluid viscosity. Final dose for either product requires optimisation with the actual fluid and operating conditions.

What data determine crude oil demulsifier selection?
Demulsifier selection starts with a sample representing the actual stream, process temperature, emulsion stability, residence time, and the oil and water acceptance limits. A bottle test screens candidates; a field trial then proves dose, injection point, interface quality, re-emulsion tendency, BS&W, separated-water quality, and programme cost.
| Buyer input | Decision affected | Acceptance evidence |
|---|---|---|
| Sample source, water cut, temperature, API gravity or density, and emulsion history | Candidate chemistry and test conditions representative of the process | Traceable sample and documented test conditions |
| Separator or treater, residence time, temperature, pressure, and mixing pattern | Required emulsion break and initial injection location | Interface, separation rate, rag layer, oil in water, and water in oil |
| Current product and dose, injection point, mixing distance, and production rate | Trial-dose range and implementation plan | Chemical consumption, result stability, and response to operating changes |
| BS&W limit, separated-water quality, re-emulsion risk, and downstream objective | Candidate acceptance criteria | Agreed test method, result trend, and verification samples |
ASTM D4007-22 describes the laboratory determination of water and sediment in crude oil by centrifuge. Agree the project product-quality method before the trial; bottle-test observations do not replace the BS&W test or other acceptance measurements required by the facility.
How should a comparable demulsifier bottle test be run?
A useful bottle test keeps the sample, temperature, mixing energy, observation time, and reading method consistent for every candidate. The objective is not simply to choose the bottle that looks fastest, but to identify candidates suitable for process-equipment testing without sacrificing water quality, interface stability, or repeatability.
- Take a representative sample and record its source, time, temperature, water cut, active product, and operating conditions at sampling.
- Condition every sample portion in the same way, then test candidates and doses at a consistent volume and mixing sequence.
- Record separation time, water volume, water clarity, interface sharpness, rag layer, sediment, and re-emulsion signs at predefined intervals.
- Select several candidates against all criteria—not one observation—then confirm the BS&W and water-quality methods used by the facility.
- Proceed to a controlled field trial with agreed dose limits, injection point, duration, sampling frequency, acceptance criteria, and stop conditions.
BETAFLOW DM 201
Demulsifier - OilField Chemicals
BETAFLOW DM 201 is a chemical used to break emulsions, help produce cleaner separated water, establish a clear interface, prevent re-emulsion, and reduce basic sediment and water.
Product Benefits
- Breaks the oil emulsion so water can separate more quickly.
- Helps produce oil with low BS&W and cleaner separated water.
- Published as compatible with other chemicals; confirm actual compatibility for the site programme.
Technical Specifications
| Physical Form and Odor | Density, g/cc | Water solubility | Usage Method | Packaging |
|---|---|---|---|---|
| Yellowish to brown liquid, aromatic solvent odour. | 0.9 ± 0.1 | Insoluble | BETAFLOW DM 201 is injected continuously. Initial points may include wells with heavy emulsions or high production; distance to the separation facility should provide adequate mixing and residence time. Use 5-20 ppm based on produced crude oil as the published starting range, then optimise from field results. | 200-litre drum. |
BETAFLOW DM 222
Viscosity Reducer - OilField Chemicals
BETAFLOW DM 222 is a chemical used to break emulsions and help produce lower viscosity. A viscosity reducer lowers crude-oil resistance to flow so the fluid is easier to process and move.
Product Benefits
- Breaks the oil emulsion so water can separate more quickly.
- Helps produce a fluid with lower viscosity.
- Published as compatible with other chemicals; confirm actual compatibility for the site programme.

Initial points may include wells with heavy emulsions or high production; distance to the separation facility should provide adequate mixing and residence time. Use 10-100 ppm based on produced crude oil as the published starting range, then optimise from field results. | 200-litre drum. |

Data needed for a demulsifier quotation
Send production rate, water cut, temperature, API gravity or density, BS&W result, separated-water quality, separator or treater type, residence time, current product and dose, injection point, rag-layer or re-emulsion problem, acceptance target, packaging, and destination. Use the Beta contact page so the technical team can assess sample needs, bottle testing, a field trial, and the quotation basis.
Is the demulsifier with the lowest dose always the most economical?
No. Compare cost at the same production rate and period, then account for BS&W, water quality, interface stability, re-emulsion, heating demand, packaging, delivery, injection equipment, and test support. A low dose is not economical if the separation or operating-stability target is missed.
