Frequently Asked Questions
What is UBPro-446 used for?
UBPro-446 is an oil-soluble, zinc-based hydrogen sulfide (H₂S) scavenger. It is designed to neutralize H₂S and mercaptans in oilfield production streams, refinery processes, produced water systems, and oil-based drilling muds to prevent corrosion and improve safety.
What is the typical dosage for UBPro-446?
The typical dosage range is 100 to 250 ppm (w/v). However, the optimal dosage depends heavily on the specific H₂S concentration, flow rates, operating temperature, and injection point configurations. Testing is recommended to determine the exact dosage.
Is UBPro-446 soluble in water?
No, UBPro-446 is a non-aqueous, oil-soluble formulation. It is insoluble in water and is designed specifically for complete miscibility and performance within hydrocarbon/oil phases.
What are the key storage and shelf life requirements?
UBPro-446 should be stored in a cool, dry, and well-ventilated area away from ignition sources. Keep the containers tightly sealed. It has a shelf life of 24 months from the manufacture date when stored in its original, unopened packaging.
What PPE is required when handling this product?
Personnel must wear appropriate personal protective equipment (PPE), including chemical-resistant gloves, eye protection, and respiratory protective devices where applicable, in accordance with the Material Safety Data Sheet (MSDS).
