Also, the company has previously supplied the THPS
programme with equipment corresponding to sales of approximately SEK150m.
Field-proven, Scaletreat FeS also slowly dissolves existing iron sulphide deposits at threshold concentrations levels as much as 50 per cent lower than the market's benchmark THPS
In this study we synthesized N-vinyl-2pyrrolidone/acrylic acid (VP:AA = 1:3) copolymers via THPS and MAPS methods.
Comparing THPS and MAPS methods depending on reaction times, it was demonstrated that the microwave-assisted polymerization was significantly faster than traditional heating method.
THPS is well-known as a highly effective biocide for a variety of water-treatment applications including oilfield downhole treating.
Tests have shown that 1,000 ml of 20% concentrate of formulated THPS solution will effect the dissolution of approximately 120 grams of iron sulfides (two types tested: trolite [FeS] and pyrite [FeS2]).
The study reads: "We conclude that SRB may have developed low level microbial resistance to THPS
based biocides as higher doses are required to inhibit their activities.
We have also identified derivatives of THP and THPS
with a bleaching power higher than that of [Na.
All the gnarlers are awaiting another video game from you guys because it's realistic, unlike THPS
, doing 18-foot ollies off flat and shit.
