    (Видавництво Львівської політехніки, 2020-10-10) Topal, Alexander; Holenko, Iryna; Haponych, Luidmyla; Coal Energy Technology Institute of National Academy of Sciences of Ukraine
    For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.

    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.
