Tetrakis(hydroxymethyl) phosphonium sulfate for Sale
Tetrakis(hydroxymethyl) phosphonium sulfate (THPS) is a versatile, broad-spectrum biocide and flame retardant widely utilized in the oil and gas, water treatment, and textile industries. As a leading manufacturer and exporter, Hoochemtec provides high-purity THPS 75% liquid, specifically formulated to eliminate sulfate-reducing bacteria (SRB) and prevent iron sulfide scale
Key Features & Benefits
- Rapid Kill Rate: Exhibits fast-acting control over aerobic and anaerobic bacteria, fungi, and algae.
- SRB Specialist: Specifically effective against Sulfate-Reducing Bacteria that cause reservoir souring and MIC (Microbially Influenced Corrosion).
- Eco-Friendly: Quickly breaks down into non-toxic substances in the environment; no bioaccumulation.
- High Solubility: Fully miscible in water and remains stable in both acidic and alkaline environments.
- Scale Synergist: Dissolves existing iron sulfide deposits, improving flow efficiency in pipelines.
What is THPS Used for
-
Oilfield & Gas Production: THPS is the industry standard for controlling microbial growth in injection water, drilling muds, and completion fluids. It effectively neutralizes hydrogen sulfide (H2S) and prevents the “souring” of oil wells.
-
Industrial Water Treatment: Serves as a highly effective biocide for cooling towers, process water, and boiler water, controlling microbial growth while minimizing corrosion risk.
-
Textile Flame Retardant: A primary agent for the durable flame-retardant finishing of cotton, polyester, and blended fabrics. It provides excellent thermal stability without compromising fabric texture.
FAQs of THPS
At use-concentrations, THPS is significantly less corrosive to carbon steel and stainless steel than many other oxidizing biocides.
Dosage typically ranges from 15–100 ppm depending on the severity of contamination. Our technical team can provide a site-specific dosing schedule.
Yes. In addition to the standard THPS 75% solution, Hoochemtec can dilute the product to 20%, 30%, or 50% based on customer requirements, or formulate it with corrosion inhibitors for specific applications.
This product is supplied in standard 250kgs/drum.
THPS is stable when stored properly; however, it undergoes degradation in high-temperature or strongly alkaline environments.
Storage Conditions: It should be stored in tightly sealed original containers, preferably constructed from high-density, high-molecular-weight polyethylene.
