Item Dissolution polydisperse solid phase in the gas-liquid flow(Lviv Polytechnic Publishing House, 2016) Danylyuk, Oleh; Atamanyuk, Volodymyr; Halaniya, Oksana; Lviv Polytechnic National UniversityThe thesis investigatesdissolution polydisperse solid phase to gas-liquid flow. In particular, a study of single particle dissolution of K2 SO 4 in a suspension and determined masstransfer coefficientβ. The scheme of the experimental setup is presented. Confirmed independence factor masstransfer the diameter of the particles during dissolution in the gas-liquid flow. Theoretical calculation dissolution of polydisperse phase based on the kinetic process model and compared with experimental data.Item The study of swelling and solubility of crumb rubber in the medium of residual base oil(Lviv Polytechnic Publishing House, 2016) Nagurskyy, Andriy; Grynyshyn, Oleg; Khlibyshyn, Yuriy; Fedoriv, Ruslan; Lviv Polytechnic National UniversityResearch swelling and dissolution process crumb rubber in the residual base oil. The influence of grain size crumb rubber in the process of dissolving and swelling.Item Dissolution of solid polydisperse materials during pneumatic mixing(Видавництво Львівської політехніки, 2017-12-23) Danyliuk, Oleh; Atamanyuk, Volodymyr; Bachyk, Mariia; Romanov, Vadym; Lviv Polytechnic National UniversityThe thesis investigates dissolution of solid polydisperse materials during pneumatic mixing. In particular, a study of kinetics regularities of dissolution of C6H5COOH in water. The methods of experimentations are described. It has been experimentally established that with increasing air flow, the duration of the dissolution process is reduced. The influence of mixing applications on the dissolution process is described. The advantages of the dissolution process during the pneumatic mixing of the solution are analyzed.
