FIELD: oil industry, particularly to prevent salt deposits in collector and measuring installations during oil production and transportation.
SUBSTANCE: method involves mixing product flows and transporting thereof, wherein compatible liquids are chosen for further mixing so that during mixing of above liquids oversaturated salt solution does not appear to prevent salt precipitation. Liquid for mixing is taken in amount enough to reduce salt concentration to value, which does not exceed saturated concentration and provides mineralization obtaining after liquid mixing. Mixing of liquid flows is performed out of process equipment and in tubes provided with release coating applied on inner tube surfaces.
EFFECT: increased simplicity due to elimination of chemical reagent usage and due to reduced number of stages.
