    Wide Operational Flexibility

    Maintains effective performance across a broad range of temperatures and pressures, compatible with diverse field configurations and production profiles.

    Direct-Injection Ready

    Low-viscosity liquid formulation enables seamless integration into existing chemical injection systems without additional modification or dilution steps.

    Deployment Contexts

    Applications

    01
    Oil & Gas Production Systems Scavenging of H₂S from crude oil streams, associated gas phases, and multiphase flow lines at wellhead and downstream processing stages.
    02
    Produced Water Treatment Elimination of dissolved sulfides from produced water prior to surface discharge or subsurface reinjection, ensuring regulatory compliance and corrosion prevention.
    03
    Refining & Petrochemical Operations Protection of heat exchangers, distillation columns, and downstream process equipment from sulfide-induced corrosion in refinery service.
    04
    Oil-Based Drilling Mud Systems Suppression of sulfide ingress and contamination within oil-based mud formulations during drilling operations in sour formations.
    Safe Handling & PPE Requirements
    UBPro-446 is classified as an industrial chemical and must be handled in accordance with applicable occupational health and safety regulations. All personnel involved in handling, transfer, or injection operations are required to wear appropriate personal protective equipment (PPE), including chemical-resistant gloves, eye protection, and where applicable, respiratory protective devices. Full handling protocols, exposure limits, first-aid measures, and emergency response procedures are specified in the Material Safety Data Sheet (MSDS), which must be reviewed prior to use and kept accessible at all times.

    Common Questions

    Frequently Asked Questions

    Q: What is the primary application phase of UBPro-446?

    UBPro-446 is a non-aqueous, oil-soluble scavenger specifically formulated for complete miscibility in hydrocarbon systems. It is designed to treat H₂S directly in the oil phase, associated gas phases, and multiphase flow streams.

    Q: What is the active chemical basis of UBPro-446?

    The product is formulated on a zinc-based (Zn²⁺) active scavenger basis, which provides rapid, stoichiometrically efficient, and stable neutralization of hydrogen sulfide and mercaptans.

    Q: How is UBPro-446 dosed into systems?

    It features a low-viscosity liquid formulation ready for direct injection. The typical dosage range is 100 to 250 ppm (w/v), though the optimal rate depends on in-situ H₂S concentrations, temperatures, and field configurations.

    Q: Where can UBPro-446 be deployed?

    It is highly flexible and suitable for oil & gas production systems (wellhead and downstream), produced water treatment, refinery operations (protecting distillation columns and heat exchangers), and oil-based drilling mud systems.

    Q: What are the storage requirements and shelf life?

    UBPro-446 should be stored in a cool, dry, well-ventilated area away from ignition sources with containers tightly sealed. It has a shelf life of 24 months from the date of manufacture when kept in its original, unopened packaging.

    Q: What PPE is required when handling this product?

    Personnel must wear chemical-resistant gloves, eye protection, and appropriate respiratory protective devices as specified in the Material Safety Data Sheet (MSDS) before proceeding with transfers or injection operations.
