The procedure for automatic calibration of process parameters of electric adsorption mass transfer devices for selective purification of gas emissions is presented on the example of a continuous electric adsorber with a moving adsorbent bed. The calibration program is based on automatic recognition of the ranges of regulation of the operating modes of electric sorption devices at the stage of commissioning or during the current operation of technological mass transfer equipment. The hydrodynamics of the filtration flow through the adsorbent bed and the parameters of the electric field are subject to calibration, while the optimal filtration regimes from the point of view of washing the adsorbent granules with a continuous gas phase flow are recognized. Determination of the control limits for the parameters of the electric field is based on an automatic check of the quality of electrical insulation part of the mass transfer device, as well as recognition of the current arising in the circuit when ions move between charged surfaces (ionic wind). The calibration program and the parameters obtained with its help will enable the self-adaptive system of automated control of electrical adsorption processes to achieve the highest rates of purification of gas emissions, with optimal energy costs for the implementation of mass transfer processes and will provide an opportunity to smooth out technological, large-scale and other factors inherent in specific mass transfer processes and device designs.
