Application:
THPS is a biocide effective against micropest in industrial cooling systems, oil field operations, and paper-making industry. The advantage is it will soon degrade to a nontoxic substance immediately after use.
Also it can be applied to fabric coating, obviously improving ¡£flame retarding property.
In 1997, the product passed the attestation in the United States of America and was formally put into use in the field of environmental protection. In the same year, it was awarded with American Green Chemicals Award.
In the petroleum industry, THPS exhibits excellent activity against problem microorganisms. In particular it is extremely effective against sulphate reducing bacteria ( S.R.B), a major cause of hydrogen sulphide souring and corrosion. Formulations containing THPS may be used in many applications where microbiological contamination is present and they have extensive use in enhanced oil recovery injection water systems, topside recovery systems, pipeline protection and storage.
Many benefits of using THPS formulations are very important in industrial water treatment applications. THPS produces a rapid kill against a broad spectrum of bacteria and when suitably formulated with a surfactant it readily eradicates unwanted biofilms. The excellent toxicity profile of THPS and ease of deactivation to a virtually non toxic substance makes it an ideal biocide to use when cooling water is discharged into ecologically sensitive waters. THPS is compatible with all types of water used in cooling systems and effective minimum dose levels can be quickly achieved through use of an easy on-site analytical method.
