High-Performance H₂S Scavenger for Oil, Gas & Water Treatment from China Suppliers and Factory
Product Introduction
UBPro-445 is a highly effective, zinc-based, dual-soluble sulfur scavenger designed for use in both hydrocarbon (oil/gas) and aqueous systems. Its advanced formulation enables efficient neutralization and removal of hydrogen sulfide (H₂S) and mercaptans across a wide range of applications, including crude oil, natural gas, produced water, and oil-based drilling fluids.
The product demonstrates excellent performance under both continuous injection and batch treatment conditions. Due to its dual solubility, UBPro-445 ensures comprehensive phase coverage, improving treatment efficiency and operational flexibility. It is particularly suitable for eliminating high concentrations of H₂S overflow in drilling operations, making desulfurization processes safer, more efficient, and easier to manage.
UBPro-445 forms stable, soluble reaction products, ensuring no secondary pollution and minimizing risks of scaling or deposition.

Recommended Handling
The recommended dosage is highly dependent on system-specific parameters such as concentration of H₂S. A typical treatment range is 100 - 300 ppm (w/v), but a pilot test is required for optimal results.
Handle as an industrial chemical wearing protective equipment and observing the precautions described in the Material Safety Data Sheet (MSDS).
Notes: Field trials are recommended for optimal dosage determination.
Packaging and Storage
- Available in 200L/Drum or 1000L IBC packaging.
- Store in dry, well-ventilated area. Keep container closed. Keep away from heat, sparks and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and/or stacking.
Performance Evaluation (Lab Simulation Test)
| Test Item | Test Conditions | Result |
|---|---|---|
| Initial H₂S Concentration | H₂S gas cylinder | 100 ppm |
| Dosage | UBPro-445 | 50 ppm |
| Reaction Time | Static mixing at ambient temperature | 3 minutes |
| Residual H₂S (Liquid Phase) | After treatment | ≤ 4 ppm |
| Residual H₂S (Gas Phase) | After treatment | Below detection limit |
Testing Method: Laboratory simulations were conducted using H₂S gas to replicate field conditions in sour oil and gas gathering systems. Colorimetric tubes were used as the medium for chemical injection, reaction monitoring, and H₂S concentration measurement.
Frequently Asked Questions (FAQ)
What is UBPro-445?
UBPro-445 is a highly effective, zinc-based, dual-soluble sulfur scavenger designed to remove hydrogen sulfide (H₂S) and mercaptans in both hydrocarbon (oil/gas) and aqueous systems.
In what applications can UBPro-445 be used?
It is suitable for oil & gas gathering systems, crude oil and natural gas treatment, produced water treatment, water-based drilling muds, refining, petrochemicals, and systems with high H₂S concentrations.
What is meant by "dual solubility" and its benefits?
Dual solubility means the chemical is active in both oil and water phases. This ensures comprehensive phase coverage, which improves overall treatment efficiency and operational flexibility.
Does UBPro-445 cause scale deposits or secondary pollution?
No. UBPro-445 forms stable, soluble reaction products that remain dissolved, preventing scaling, deposition, and secondary pollution.
What is the recommended dosage for UBPro-445?
The typical treatment range is 100 - 300 ppm (w/v). However, because dosage is highly dependent on system-specific parameters, a pilot test or field trial is recommended to determine the optimal amount.
How should UBPro-445 be stored?
It should be stored in a dry, well-ventilated area with the container closed. Keep it away from heat, sparks, open flames, and incompatible materials. Follow standard safe warehousing practices.
