Title:
A PROCESSING METHOD FOR WASTE RESIDUE PRODUCED BY BURNING AND DESULFURIZING OIL DREGS
Document Type and Number:
WIPO Patent Application WO/2009/059494
Kind Code:
A1
Abstract:
A manufacturing method for building material is provided. Concretely, a processing method for a waste residue produced by burning and desulfurizing oil dregs in oil refining is provided. Waste residue produced by burning and desulfurizing oil dregs in oil refining hasn't been disposed and utilized at all for a long time, thus a method for processing the waste residue is provided. The main raw material in the method is waste residue produced by burning and desulfurizing oil dregs,including fly ash and bottom dregs. Dilute sulfuric acid solution is putted into the main raw material as the additive. The amount of the additive is depended upon the content of CaO in the main raw material and the concentration of the dilute sulfuric acid solution. The advantages of the method are as follows: processing and utilizing essentially waste residue produced in oil refining, improving the rate of utilization, decreasing the amount of natural resources used, reducing the cost of producing brick and block, saving energy sources, decreasing discharge, and protecting environment.
