Hanoshenko O. Reduction of the technology-related load on the environment under the disposal of waste automobile oil filters

The thesis is devoted to the actual problem of reducing the technology-related load on the environment at the disposal of waste automobile oil filters by preliminary filter paper processing by means of a washing solution with the residual oil extraction before further thermal decontamination. The fact of negative influence of waste automobile oil filters on the environment for the Poltava region conditions has been experimentally confirmed. Therefore, at the first stage of integrated recycling technology, it is necessary to organize their сollecting. For this purpose, a container method for the separate collection of waste automobile oil filters is proposed, which will allow to pre-sort them and collect separately according to standard sizes and separate the waste oil with its subsequent drain. The design of the container is protected by a utility model patent. Experimental research on the detergent choice has made it possible to determine that the most promising detergent reagent for solving the problem is sodium percarbonate Na2CO3∙1,5H2O2. In order to determine the maximum efficiency of cleaning the filter paper of the waste automobile oil filter, a mathematical model was developed and a stationary (saddle) point was obtained that determined the optimal ratio of the technological process parameters. The evaluation of the developed technology for compliance with ecological requirements has been carried out. It showed that the preliminary treatment of filter paper with a washing solution can reduce the technology-related load on the environment. So the amount of waste oil is reduced by 55%, and the amount of pollutants in fume gases is: sulfur dioxide – 89%, nitrogen dioxide – 15%, carbon monoxide – 66%, soot – 86%.
