Introduction. Today, one of the main problems in gas processing plants is the loss of amine solution (absorbent) during the absorption process. The main reason for this is that in the process of cleaning gases from sour components with amine solutions, it foams as a result of various effects, and a certain part of the amine solution comes out with the purified gas and passes into the saturated amine solution. Normal foam turns into foam by contaminating surfactants. The most common foam control method is to add antifoam chemicals to the circulating solution stream to suppress foam[1]. Foaming in the absorber device during the amine gas purification process occurs due to various reasons.
Chemical methods of combating foaming are widely used in various fields. This method is very effective and sometimes the only acceptable method. A drop of defoamer is attracted to the bubble and spreads over the separation surface, reducing the film strength. As a result, small bubbles coalesce into larger ones, which are less stable and burst as they rise to the surface [2]. Therefore, the demand for chemicals that reduce or eliminate foaming is very high today. In order to eliminate this problem, foam extinguishers were
synthesized. This article describes the production technology of foam extinguishers.
Experimental parts. Based on the proposed technology (Fig. 1), a mixture of reagents (waste hexane) required for the composition was sucked from the tank (1) using a pump (7). After that, it was sent to the rectification furnace (2) for fractionation. In the rectification boiler (2), the temperature was 130°C-170°C, the pressure was 1.5-2 atm, and the time duration was 30 seconds [3-5]. Fraction II from the rectification boiler (2) was sent to the jacketed reactor (3) at 130°C-170°C to carry out the synthesis process with waste hexane mixture with oxidants in a ratio of 1.1:1 [6-8]. Oxidizing compounds (boric acid and hydrogen peroxide) in a 1:1 ratio were sent to the jacketed reactor (3) through the upper capacity (4). Products were mixed using a mixer (8) in a jacketed reactor (3). In order to provide heat, hot water was introduced from the lower part of the reactor (3) and discharged from the upper part. In the reactor (3), the temperature difference increased to 60°C in the first 30 minutes, and from the next 45 minutes it was kept around 85°C-90°C.

From the 55th minute to the 120th minute, it was 95°C-105°C[9-11]. The temperature in the jacketed reactor (3) was maintained in the range of 95°C-105°C, the pressure was 1.3-1.8 atm., and the duration of the process was 120 minutes[12-14]. The resulting product was sucked from the lower part of the jacketed reactor (3) using a pump (7). Then, it was inserted from the middle part of the rectification skull (5) to divide it into fractions. In the rectification chamber (5), the temperature was 94°C-103°C, the pressure was 1-1.7 atm, and the time duration was 30 minutes. The light fraction unreacted
product from the upper part of the rectification boiler (5) was circulated back to the jacketed reactor (3) for processing. The TSU-1 foam quencher obtained at a temperature of 95°C-105°C was sent to the finished product capacity (6). For a certain period of time, the TSU-1 foam extinguisher was stored in the tank (6) for cooling purposes. After cooling, the finished product was removed from the container (6). Table 1 below shows the addition ratios of all reagents used for the synthesis process: boric acid, waste hexane, and hydrogen peroxide.

Conclusion. In this article, it can be concluded that a mixture of fraction II waste hexane at a temperature of 130°C-170°C was used to obtain the TSU-1 foam extinguisher. The pressure in the jacketed reactor used for its production was 1.3-1.8 atm, the temperature was 95°C-105°C, and the time duration was 120 minutes. TSU-1 synthetic foam extinguisher was produced for the purpose of extinguishing the foam generated during the gas cleaning process. Also, the laboratory tests on extinguishing the foam formed in the absorber during
gas cleaning were successfully carried out. The following results were obtained on the basis of various analyzes of the TSU-1 substance synthesized on the basis of this technological production scheme: the economic effect of using a foam suppressor is effective in suppressing the foam formed in the absorber during gas purification;
It was found that it is much cheaper than analogues brought from abroad, and the coefficient of useful work is high.
