METHOD OF PRODUCING HIGH-EFFICIENCY DEPRESSANT SUSPENSIONS Russian patent published in 2020 - IPC C10L1/196 C10L1/10 C08F2/00

Abstract RU 2714673 C2

FIELD: oil and gas industry.

SUBSTANCE: present invention relates to a method of producing dispersion-type effective reagents used in petrochemistry and oil refining. Method involves obtaining a concentrated suspension consisting of 23 % polymer Savilen 11407-027 and a mixture of solvents of toluene 19 %, isopropyl alcohol 29 % and butanol 26 % with addition of a stabilizer – BASF FA 4601 – 3 %. Method enables to obtain a depressant and an inhibitor of asphaltene-resin-paraffin deposits with concentration of the polymer base of 23 % and good processing properties.

EFFECT: this system of solvents is selected so that the produced disperse system is stable and homogeneous.
