FIELD: gas industry.

SUBSTANCE: invention relates to a method for controlling a device for wet desulfurization of flue gases containing an absorption column and at least one circulation pump to ensure the circulation of absorbent liquid in the absorption column and performing desulfurization by bringing absorbent liquid in the absorption column into a gas-liquid contact with exhaust gases formed in a fuel combustion device, while the specified control method includes: a stage of creating the first training model using machine learning on a ratio between future concentration of sulfur dioxide at an outlet of the absorption column and operational data of the fuel combustion device and the device for wet desulfurization of flue gases, including a flow rate of the absorbent liquid circulation; a stage of forming, using the first learning model, the first table of the ratio between the flow rate of the absorbent fluid circulation at the first time and the concentration of sulfur dioxide in the exhaust gas from the absorption column at the second time, which is the time in the future relatively to the first time; a stage of selecting, based on the first table of the ratio, the flow rate of the absorbent liquid circulation at the first time, at which the concentration of sulfur dioxide in the exhaust gas from the absorption column at the second time does not exceed a predetermined value; and a stage of regulating an operating mode of the specified at least one circulation pump based on the selected circulation flow rate at the first time.

EFFECT: obtaining a device and method for controlling a device for wet desulfurization.
