The work aims at improving the efficiency of greenhouse gas utilisation processes, namely carbon dioxide. The principle of operation of the designed equipment is to realise the process of ultrasonic absorption (absorption of gas by liquid) when carbon dioxide is fed over the surface of the liquid, in which cavitation occurs. The source of the cavitation action is a plate that oscillates with a given frequency and amplitude. The efficiency of the ultrasonic gas absorption process is determined by the parameters of plate oscillations. In particular, to ensure the necessary and sufficient amplitude of plate oscillations and uniformity of its distribution along the plate, it is proposed to solve the problem of optimal placement of the required number of ultrasonic emitters of a given size. As a criterion of optimality, it is proposed to use the integral power of oscillations of the whole plate, formed by a certain number of emitters. The proposed and developed numerical model of oscillation formation in the plate is based on the solution of the biharmonic equation for the distribution of amplitudes of oscillations, taking into account the finiteness of its thickness and provides the choice of the number, location, and size of ultrasonic emitters required to solve a particular problem. The simulation results allowed us to establish that the optimal location of the emitters depends on specific characteristics that must be taken into account when solving the problem of optimising the size and location of ultrasonic emitters for each particular plate. The calculations showed high efficiency of the created model and the possibility of its practical application for solving the problems of utilisation of greenhouse gas emissions in agriculture.
