METHOD OF PROCESSING OIL SLIMES AND CLEANING OF OIL CONTAMINATED SOILS Russian patent published in 2012 - IPC B09C1/10

Abstract RU 2450873 C2

FIELD: process engineering.

SUBSTANCE: invention relates to ecology, particularly, to reclamation of oil contaminated soils. In compliance with this invention, slimes of heat power plant chemical water cleaning are used as alkaline agent. Proposed process is carried out in highly loaded dump pit aerated at bottom by high-pressure pumps. At dump pit bottom, process is performed by intermittent mixing by gantry clamshell unless compost temperature reduces to ambient temperature. Compost temperature variation is determined by claimed mathematical expression. Process termination time is defined from claimed formulas.

EFFECT: process duration decreased from 1-3 months to 18-30 days.
