Technology of conversion of materials of power and oil refining objects

Abstract

Quantitative and qualitative characteristics of multi-ton materials in Ukraine and in Ivano-Frankivsk region, which Quantitative and qualitative characteristics of multi-ton materials in Ukraine and in Ivano-Frankivsk region, which contain energy components, are given. It is proposed to process water treatment sludges containing petro-leum products by preparing a raw material mixture from the following man-made substances: oil sludge, ash, zeo-lite screenings, calcium-containing compounds and viscous materials. The optimal composition of the raw material mixture is as follows: as a filler for construction products (concrete): ash – 60-65 %, liquid glass s olution – 5-7 %, limestone dust – 3-5 %, organic additives – 7-10 %, soda ash – 10-12 %, which is granulated and heat t reated at 120-140 °C. The research results and technical char acteristics of the obtained granular materials, which are formed from a mixture containing a significant amount of hydrocarbon sludge, have lower strength, but greater porosity and lower thermal conductivity. Granules from a mixture № 4-7 are characterized by higher strength, and due to their properties they belong to the structural and thermal insulation materials. The technology of obtaining a raw material mixture for soda production is based on the LeBlanc process – the interaction in the seco nd stage of sodium sulfate, carbon and calcium carbonate with the formation of calcium sulfide, sodium carbonate and carbon (IV) oxide. It is proposed to prepare a raw mixture for the production of sodium carbonate from sodium sulfate con-taining petroleum product, which is formed by the technology of obtaining oxygen-containing additives, and sludge containing petroleum products, which will provide a high temperature during the soda production process. The processing of sludge from oil refining and energy facilities into granular materials shows that they can be used in the construction industry and soda production, which reduces the energy consumption of the processes of obtaining such materials.
