Beregovaya N.G., Gerasimenko V.V., Molchanov S.A., Morozov M.M. OUTLOOK RECYCLING SPENT TYPE ZEOLITE NAX ORENBURG GAS CHEMICAL COMPLEXNaH type zeolites used in industry for drying and deep fine purification of gases and liquids, for the separation of gaseous and liquid mixtures, separation of a mixture of hydrocarbons in a cryogenic air separation plant. Used zeolites Orenburg gas chemical complex is placed on authorized landfill gas production management and refers to the IV and V classes of hazard. Zeolites are unusable production waste. The paper presents experimental data on the reuse of waste zeolites. Laboratory studies were carried out on the basis of a branch of Gubkin Russian State University of Oil and Gas in Orenburg. A variant of asphalt production with the introduction of the grain portion of these zeolites. On the basis of the experiments selected the optimal component composition of the experimental asphalt. A variant of the use of waste zeolites — putting them in the concrete mix as a placeholder. It was found optimal amount of spent zeolite added to the composition of the resulting samples. A technique for obtaining samples of concrete mixtures and their composition. Determine their strength properties, such as water saturation, swelling, tensile strength, and coefficient of frost-grade asphalt and concrete strength. Depending on the strength of the samples revealed the content of the waste in their composition zeolite the possibility of using zeolites in agriculture. The developed technology allows to relieve the landfill and reduce the environmental burden on the region. Implementation of the proposed technologies in production will be accompanied by extra profit.Key words: zeolite, asphalt, concrete.
