    Key Benefits

    Oil-Phase Solubility

    Complete miscibility within hydrocarbon systems ensures thorough contact and treatment efficiency across liquid and multiphase flow streams.

    High Reaction Efficiency

    Achieves rapid, stoichiometrically favorable neutralization of both H₂S and mercaptans, minimizing breakthrough risk under variable loading conditions.

    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

    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.

    Frequently Asked Questions (FAQ)

    What is the chemical basis of UBPro-446?

    UBPro-446 is formulated on a zinc-based (Zn²⁺) active scavenger basis, specifically engineered in a non-aqueous, oil-soluble phase to target hydrogen sulfide and mercaptans in hydrocarbon systems.

    Is UBPro-446 soluble in water?

    No, UBPro-446 is insoluble in water. It is a non-aqueous, oil-soluble formulation designed for complete miscibility within hydrocarbon phases and oil-phase streams.

    What is the typical dosage range for this scavenger?

    The typical dosage range is between 100 to 250 ppm (w/v). However, the optimal dosage depends on factors such as temperature, flow rate, and the concentration of H₂S present in the system.

    Where can UBPro-446 be deployed?

    It is highly effective for oil and gas production systems (crude oil and associated gas), produced water treatment, refining and petrochemical operations, and oil-based drilling mud systems.

    What are the storage requirements and shelf life?

    UBPro-446 should be stored in a cool, dry, and 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.

    What safety precautions must be taken when handling UBPro-446?

    Personnel must wear appropriate personal protective equipment (PPE) including chemical-resistant gloves, eye protection, and respiratory protective devices where necessary. Refer to the Material Safety Data Sheet (MSDS) before use.
