INHIBITION OF SEDIMENTATION

摘要

FIELD: process engineering.SUBSTANCE: claimed invention relates to inhibition of sediments in a water system, for example, barium-bearing sediments and can be used in oil production and for water treatment. Claimed process comprises the addition of the threshold amount of sedimentation inhibitor composed by aminoacid modified by alkyl phosphonic acid. The aminoacid fragments can be composed of α-aminoacid or aminoacid containing two or more carbon atoms between carboxyl group and aminoacid. Said inhibitors feature notably improved process characteristics and better compatibility with the systems compared to available known compositions.EFFECT: higher efficiency of inhibition and control over toughness and alkalinity.10 cl, 3 tbl, 47 ex
