Возможности применения промышленной воды предприятий нефтегазового комплекса для получения противопожарных пен

Abstract

Introduction. One of the distinctive features of fires at oil and gas facilities is the need for constant replenishment of the water supply used by fire departments in the shortest possible time. There is a need for the use of industrial waters in the organization of extinguishing fires of oil and petroleum products. In this paper discusses the features of the usage of industrial waters to obtain premixes of foaming agents used for foam fire extinguishing. For this purpose, an assessment of the technical indicators of the quality of working solutions of foaming agents was carried out using models of drinking, circulating and seawater. Goals and objectives. Conducting research on the foaming ability of standard foaming agents with water, in its composition as close as possible to the requirements of regulatory documents to recycled industrial water. Methods. The following laboratory methods were used in the work: volumetric analysis, complexometric titration, tensiometry, standard methods of testing foaming agents to assess their quality. Results and discussion. The total salinity in waters of various types increases in the range from drinking to sea water. Recycled water at the maximum values of salt additives occupies an average intermediate value, including in terms of water hardness, which gave a difference in foaming characteristics. The difference between the hardness of drinking and model circulating water is significant, which affects the foaming due to the flow of ionic processes in such systems and probably leads to a decrease in expansion factor of the resulting air-mechanical foam. The possibility of using industrial waters to produce firefighting foams has been experimentally confirmed. A model of recycled industrial water has been developed, which made it possible to evaluate the extinguishing efficiency of foam obtained on its basis in laboratory conditions. Conclusion. A comprehensive analysis of the obtained data shows that foaming agents, application field of which does not imply the use of sea water, can be used to prepare premixes in ordinary drinking water, as well as in recycled water used in the technological cycles of industrial enterprises, which in some cases simplifies the practical issues of obtaining fire-fighting foams for extinguishing fires.
