Development of innovative resource-saving technologies of utilization of the oil containing wastes

Abstract

Formation of wastes is a considerable problem for enterprises and structural subdivisions of railways. Technological heavy mineral oils and oils apply to such wastes annually accumulating in great amounts. The method of utilization depends on composition of waste, his properties and amount. In article traditional methods of utilization and renewal of the fulfilled lubricant cooling fluids, petropolluted soil, used motor oils of separate brands are considered. The analysis of current technologies and schemes of regeneration and utilization of the oil containing wastes led to drawing the conclusion that the physical-and-chemical methods are the most promising, in particular the use of different types of advanced surface-active substances (surfactants). We conducted the laboratory studies to recover the properties of the oil containing wastes with a wide range of surface-active substances (surfactants). Specifically, some quantity of surfactants tested, among which oxyethylated monoalkylphenylic acid (neonol AF 9-12) for lubricant cooling fluids, Syntanol ALM-10 for petropolluted soil, neonol AF 9-12 for motor oil gave the best results. In developing the scheme of recovery of operating quality of the oil containing wastes for the purpose of forming and calculating the process flow diagram suggested, the process optimization, namely temperature, reagent amount, and time of its contact with oil was conducted. The new technologies with use of surface-active substances are offered.
