FIELD: oil and gas extractive industry.
SUBSTANCE: method for detecting amount of organic acids in oil flows, includes: a) eradiation of sample of said oil flow by infrared radiation; b) determining spectrum of infrared absorption, while given eradiation is performed only in ranges of spectrum with frequencies from 1000 to 1350 sm-1, from 1550 to 2200 sm-1, from 2400 to 2770 sm-1 and from 3420 to 4800 sm-1; and c) finding relation between all said frequencies of said spectrum of infrared absorption, determined at stage b), and content of organic acids in said oil flow with use of linear multidimensional regression analysis. Also provided are method for optimizing mixing of two and more product oil flows, containing organic acids with different total acid value levels and method for optimization of agents admixture, which neutralize organic acids, to product oil flow.
EFFECT: higher efficiency.
