The characteristics of the removed contaminants from fuel tanks are described. The advantages and disadvantages of the most effective fluorinated washing liquids are described, the properties of freon-113 are described in detail. In connection with the decisions made at PA YuzhMash, a number of cleaning and degreasing technological processes were revised in order to exclude Freon 113 from the technological cycle. For the bulk of DAT, the degreasing technology was changed: the dipping method was replaced by the flooding method, degreasing in the vapor-gas phase of hladon-113 at the UOF-2 unit was excluded, the operational consumption rates were revised in order to reduce them, the equipment used was revised. In addition, gasoline and water-based detergents began to be used as technological materials instead of hladon-113. The necessity of using surfactant-based washing liquids has been substantiated. The applicability of cleaning liquids has been determined depending on the design features of the surfaces to be cleaned. Requirements have been made for alternative cleaning fluids. Multicomponent hydrocarbon solvents are obtained mainly on the basis of gasoline and kerosene fractions, as well as special petroleum solvents, which are obtained by strict selection of group hydrocarbon and fractional compositions - nefras, solvents and other hydrocarbon solvents for special purposes (Petrov’s contact, cresols, etc.). On the basis of the regulatory framework of the industry and international standards presented in the article, an analysis of the possibility of using existing solvents instead of hladon-113 is carried out. Recommendations for the use of types of washing liquids from the types of in-tank elements are also given.</strong></p&gt;}, number={4}, journal={Journal of Rocket-Space Technology}, author={Кулик, О.В. and Желтов, П.Н. and Абраменко, Д.С.}, year={2021}, month={Nov.}, pages={95-105} }
