Abstract

The problem of improving environmental safety in the handling of oily waste and sludge is relevant for most industries. Significant amounts of waste oil adversely affect virtually all components of the environment. However, it is also a valuable hydrocarbon feedstock. Thus, a rational approach to the processing of sludge can have a significant environmental and economic effect. The shortcomings of traditional thermal technologies for the disposal of technological sludge and suggests using much cheaper mechanical methods were discussed in this article. For example, install decanters of various designs in a depot depending on the overall composition of the sludge and the composition of each of its main parts: the carbon-containing part, water and mechanical impurities. A modern scheme for the disposal of technological sludge from railway infrastructure enterprises has been proposed. Such a scheme allows to reduce the man-made load associated with their accumulation, circulation and minimization. The most promising example of the use of the proposed technology of utilization of oil sludge is its implementation at the local sewage treatment plants of locomotive and wagon depots.
