The process of sulfation products neutralization in the production of surfactants is not basic, but at this stage the positive effects obtained at the stage of sulfation of organic matter with sulfur trioxide gas are fixed. To preserve the degree of sulfation obtained, it is necessary to carry out the neutralization process under conditions precluding the occurrence of hydrolysis in an acidic medium. The neutralization reaction takes place with a high heat release of about 40 kJ / mol. Analysis of the literature data showed that the neutralization process is not well covered. Little data and hardware and technological design of the process. The process of neutralization in industrial conditions is carried out in apparatus with mechanical turbine mixers, to remove the heat of the exothermic reaction, the paste from the neutralizer is fed into a water-borne heat exchanger and returns to the neutralizer again. The purpose of this study is to determine the optimal technological parameters of the process of neutralization of sulfate products and the development of a mathematical model of this process. The results of experimental studies of the process of sulfation products neutralization with an aqueous solution of sodium hydroxide are presented. During the research, the influence of technological parameters on the quality indicators of neutralization products was determined, the main of which is the degree of sulfation. The optimal technological parameters for carrying out this process in a reactor with a stirrer under laboratory conditions were found. Based on the data obtained in the basis of this process, the use of a continuous-action reactor with a turbine mixer and with a combined heat exchanger. For the transition to an industrial reactor-neutralizer, a mathematical model has been developed, which makes it possible, by means of mathematical modeling, to correct technological parameters in industrial conditions.

The article presents the sequence and results of experimental modeling of artificial oil-water emulsions based on anhydrous oil and water with density and mineralization as close as possible to the real field conditions of the researched deposits. The practical importance of simulation of artificial emulsions was due to the need to work with emulsions of different degrees of water cut, which is possible only by laboratory simulation conditions. We prepared artificial oil-water emulsion using a turbine mixer in a thermostated container. Then we set the emulsion preparation mode: number of revolutions (n1, min –1) and mixing time (t, min). We selected the optimal parameters to create stable artificial oil-water emulsions according to different types of oils.
