This study aims to address the problem of mineral salt (primarily calcium and magnesium carbonates) deposition in heat exchangers used in oil refining and production processes. The object of the study was highly mineralized and hard industrial water circulating in process heat exchange systems at oil fields and enterprises. The article describes the synthesis of a new type of inhibitor based on an aromatic compound with two amino groups, phenylenediamine C6H4N2H4, as opposed to analogs with one amino group. The synthesis process was carried out by a sulfomethylation reaction in the presence of formaldehyde and sodium hydrosulfite. The protective ability of the obtained phenylenediamine derivative C8H6N2S2O6Na2 on heat exchanger surfaces was experimentally tested. The results showed that the proposed composition effectively inhibits mineral salt deposition by 92–95% even under high thermal load conditions. The study aims to improve the efficiency of heat exchange devices and reduce energy consumption.
