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

- 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 | 100ppm |
| 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)
Q1: What is UBPro-445 and how does it work?
A1: UBPro-445 is a zinc-based, dual-soluble sulfur scavenger designed to neutralize and remove hydrogen sulfide (H₂S) and mercaptans. It works efficiently in both hydrocarbon (oil/gas) and aqueous (water) phases, offering comprehensive coverage and leaving stable, soluble reaction products.
Q2: In what applications is UBPro-445 typically used?
A2: It is widely used in oil & gas gathering and transportation systems, crude oil and natural gas treatment, produced water treatment, water-based drilling muds, refining and petrochemicals, and other systems facing high H₂S concentration challenges.
Q3: Does UBPro-445 cause secondary pollution or scaling?
A3: No. UBPro-445 forms stable, soluble reaction products that remain dissolved. This prevents secondary pollution and minimizes the risk of scaling, fouling, or deposition in the system.
Q4: What is the recommended dosage for UBPro-445?
A4: The typical treatment dosage ranges from 100 to 300 ppm (w/v). However, because dosage is highly dependent on system-specific parameters like H₂S concentration, a pilot test and field trials are recommended to determine the optimal dosage.
Q5: How fast does UBPro-445 react under laboratory simulations?
A5: In lab simulation tests using static mixing at ambient temperature, UBPro-445 reacted in just 3 minutes. With an initial H₂S concentration of 100 ppm and a 50 ppm dosage, it reduced residual liquid-phase H₂S to ≤ 4 ppm and gas-phase H₂S to below the detection limit.
Q6: What packaging options and storage conditions are required for UBPro-445?
A6: UBPro-445 is available in 200L Drums or 1000L IBCs. It should be stored in a dry, well-ventilated area with containers kept tightly closed, away from heat, sparks, flames, and incompatible materials.
