OIL-CONTAINING SLIME PROCESSING METHOD AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2005 - IPC

FIELD: petroleum processing.

SUBSTANCE: invention is meant for use in petroleum processing industry as well as in all other industries where significant amounts of oil-containing wastes are to be formed, prepared for storage, and stored for long time in slime collectors. Invention modifies method of slime processing consists in charging calcium oxide-containing working agent and oil-containing slime, vigorous stirring followed by adding liquid capable of reacting with working agent, and discharging granulated product. Modification of the above method comprises: preliminary treatment of slime to form mixture with uniform composition and viscosity by stirring and heating slime and adding an organic diluent thereto; working agent is added in two portions, the first one before slime is charged and the second simultaneously with charging, after which a liquid preheated to 60-70°C is added in amount determined as function of analysis of sample of treated oil-containing waste; components are stirred in mixer at stirrer rotation speed 100-150 rpm during 15-20 min. installation is provide by all units and devices needed for implementation of the invention.

EFFECT: enabled processing of slime independently of its nature, viscosity (crude oil, lubricating oil, mazut, goudron, and the like), time and location of disposal, and moisture content.
