Tetrakis (hydroxymethyl) phosphonium sulfate (THPS)

Colorless odorless viscous liquid

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is a water-soluble, white crystalline solid that is odorless. It is a versatile compound widely used in industrial water treatment, oil and gas production, and as a preservative in the textile, leather, and paper industries. Moreover, THPS is utilized as a flame retardant in various materials, such as textiles, plastics, and coatings, and serves as an iron sulfide scavenger. This array of applications underscores its importance in diverse industrial processes.

Energy Sector

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is prominently utilized in the energy sector, specifically in oil and gas production, drilling, and pipeline operations. It serves as an effective alternative to traditional treatments, offering advantages such as lower environmental impact and reduced toxicity. THPS is also employed to control corrosion in oilfield equipment and pipelines, enhancing their longevity and efficiency. Additionally, it functions as a clay stabilizer in drilling fluids, helping to prevent formation damage and maintain wellbore stability. A key application of THPS in this sector is its use as an iron sulfide scavenger, where it effectively prevents the accumulation of iron sulfide deposits that can lead to operational challenges. This wide range of applications highlights its significance in improving operational performance and environmental safety in the energy industry.

Water Treatment

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is highly valued in water treatment for its effectiveness as a scale and corrosion inhibitor. Its application is particularly significant in cooling towers and boilers, where it helps maintain system efficiency and prolongs equipment life. The preference for THPS in water treatment stems from its low toxicity, minimal environmental impact, and biodegradability, highlighting its role as an environmentally responsible solution for managing water quality in industrial settings.

Pulp & Paper

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is widely utilized in the pulp and paper industry for controlling microbial growth and slime formation in various paper mill systems, including white-water systems, stock pulp, and paper machine systems. It is also employed as a preservative to extend the shelf life of paper products by preventing microbial degradation during storage. Additionally, THPS plays a role in reducing sulfur-containing compounds and minimizing the formation of hydrogen sulfide gas in paper mill wastewater, contributing to improved environmental compliance and odor control.
