Popis: The purpose of this work is to choose the most efficient methods to recycle caustic waste from the naphthenic acid-removing treatment of light oil fractions. The processes of the formation of pyrophoric deposits in various industries are studied. In the context of the danger of pyrophoric iron sulfides, existing ways and means of deactivating these compounds are analyzed. A review of the patent literature showed that the studied firefighting foaming agents can be divided into two groups, such that the agents in the first group are conventionally based on hydrocarbon surfactants, whereas the agents in the second group include at least one fluorinated component. The feedstock to produce the foaming agent was chosen to be caustic waste from the treatment of light petroleum products. The process of producing a foaming agent includes the simple mixing of calculated amounts of its components at an ordinary temperature. The fire-extinguishing efficiency of this agent is nonuniquely related to the concentrations of the components. The recommended foaming agent in all its main qualities is on a par with popular brands of foaming agents and, in a number of parameters (pour point and foam-expansion ratio in a GVP-600 generator), is even superior to them.
