High-Performance Zinc-Based H₂S Scavenger for Oil, Gas & Water Treatment - China Suppliers & 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.

- 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
- 200L/Drum or 1000L IBC
- 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 and how does it work?
UBPro-445 is a highly effective, zinc-based, dual-soluble sulfur scavenger designed for both hydrocarbon (oil/gas) and aqueous systems. It works by neutralizing and removing hydrogen sulfide (H₂S) and mercaptans, converting them into stable, soluble reaction products to prevent scaling and secondary pollution.
What are the main applications of UBPro-445?
It is widely used in oil & gas gathering and transportation systems, crude oil and natural gas treatment, produced water treatment, water-based drilling muds to control sulfide contamination, systems with high H₂S concentrations, and refining & petrochemical operations to protect against sulfide corrosion.
What are the key technical specifications of UBPro-445?
UBPro-445 is a colorless to transparent liquid. It is fully soluble in water, has a neat pH value of 7.5 to 9.0, and a specific gravity (at 20℃) ranging from 0.92 to 1.05.
What is the recommended dosage for UBPro-445?
The typical treatment range is 100 - 300 ppm (w/v). However, the optimal dosage is highly dependent on system-specific parameters, such as H2S concentration, and field trials/pilot tests are recommended for precise determination.
How should UBPro-445 be stored and packaged?
UBPro-445 is packaged in 200L Drums or 1000L IBCs. It should be stored in a dry, well-ventilated area with the container kept closed. Keep it away from heat, sparks, open flames, and incompatible materials, following safe warehousing practices.
How effective is UBPro-445 based on lab tests?
In lab simulation tests with an initial H₂S concentration of 100 ppm and a dosage of 50 ppm, UBPro-445 reduced residual H₂S in the liquid phase to ≤ 4 ppm within 3 minutes of static mixing at ambient temperature, bringing the gas phase H₂S below the detection limit.
