Aspects are considered of providing safe oxidative conversion of acid gases directed in plant handling ethanolaminar purification of petroleum fetching gases in a fluidized bed of spherical catalyst. Details are established of an automated machine system for controlling the process in accordance with the current transformation from hazardous production objects. A unified approach is provided for analog and digital regulators with contours for maintaining the control by reference to perturbation in the reverse-coupling contour, which allows one to use a model to realize automatic regulation in a control computer. The basis is given for regulating the optimal relationship between volume flow rates for oxygen and hydrogen sulfide.
