AQUCAR THPS 75 Water Treatment Microbiocide Antimicrobial
bacteria (SRB) which are particularly troublesome in enhanced oil recovery operations, such as injection water treatment, top-side systems, pipeline protection and storage. AQUCAR THPS 75 Water Treatment Microbiocide is a 76.5% w/w aqueous solution of. tetrakis(hydroxymethyl) phosphonium sulfate.
The source of the water that is typically utilized for the hydrotest and hull tank storage will have a direct effect on treatment requirements and associated chemical dosage and concentration ratios. Bacteria are present in all waters, so MIC is always a potential corrosion mechanism.
TetrakisHydroxymethylPhosphonium Sulfate (THPS)
Iron sulfide films on steel surfaces may cause under-deposit corrosion and, more seriously, promote hydrogen damage. Also, because iron sulfide particulates stabilise oil/water emulsions, and therefore impede separation, they may initiate environmental problems by causing oily water emissions.
CMIT/MIT has broad spectrum efficacy versus bacteria, algae, and fungi. DCOIT (4,5-dichloro-n-octyl-isothiazolin-3-one) was introduced several years ago for use as an algicide treatment for open recirculating cooling water systems. The most recent isothiazolone biocide developed for industrial water treatment is based on the MIT active alone. 7
(THPS BIOCIDE BASE ) moniotoring in sea water
Usually a minimum of 50 or 100 ppm THPS is needed to prevent planktonic bacterial growth and biofilm establishment. A much higher concentration is needed to remove established biofilms. THPS degradability, however, shortens its effectiveness in time. Prediction of THPS degradation is essential in proper dosing for operations such as hydrotesting.
The data reported in this work revealed that 50 ppm of an equimolar mixture of D-methionine, D-tyrosine, D-leucine, and D-tryptophan greatly enhanced 50 ppm THPS biocide treatment of two recalcitrant biofilm consortia containing sulfate reducing bacteria (SRB), nitrate reducing bacteria (NRB), and fermentative bacteria, etc., from oil-field
