    Problem of disposal of organochlorine waste of vinyl chloride production
    (Видавництво Львівської політехніки, 2020-02-10) Vasiychuk, Viktor; Kuchera, Yaroslav; Matskiv, Olena; Nahurskyy, Oleh; Kachan, Stepan; Lviv Polytechnic National University
    The sources of organochlorine waste formation, its toxicity, and environmental impact are analyzed, and methods of its disposal are considered. The composition of insoluble compounds in the stillage residues of the dichloroethane rectification stage before incineration is determined, and the method of their extraction is proposed. It is established that the use of oxalic and hydrochloric acids as extractants significantly reduces the iron content in the stillage residues of the rectification column, which allows increasing the duration of operation of the organochlorine waste incineration equipment.

    Influence of petrol and petroleum components’ vapours on human organism
    (Lviv Politechnic Publishing House, 2018-02-01) Matskiv, Olena; Chaika, Oksana; Babiak, Lyudmyla; Vasiichuk, Viktor; Shuvar, Natalya; Lviv Polytechnic National University; Lviv Institute of Economics and Tourism
    The work deals with the analysis of sources and ingression of petroleum vapours into environment, as well as with petrol losses and the dependence of the vapours concentration on the tank volume and the ambient temperature. The concentration of petroleum vapours at the petrol station and the individual risk of hazard level have been calculated. The chemical composition of petrol is shown, toxicity of its components and their influence on the human organism as a whole are analyzed.
