SYSTEM AND THE METHOD FOR REDUCING THE AMOUNT OF SULFUR OXIDES IN EXHAUST GAS Russian patent published in 2021 - IPC B01D53/14 

FIELD: gas industry.

SUBSTANCE: invention relates to a column with spray irrigation made with the possibility of vertical arrangement and having an internal space, and the column with spray irrigation has a central pipe of exhaust gas. It is designed to introduce exhaust gas into the interior of the column with spray irrigation through an exhaust gas inlet located at the proximal end central exhaust gas pipe. The central exhaust gas pipe is located at the lower end of the spray column in the installed position. The central exhaust gas pipe is in fluid communication with the interior of the spray column through the exhaust gas inlet at the upper end of the central exhaust gas pipe and at least one waste gas outlet for removing the purified waste gas from the interior of the spray column, wherein the exhaust gas outlet is located at the upper end of the spray column in the installed position, the exhaust gas outlet is in fluid communication with the interior of the spray column, with the total waste gas flow passing from the exhaust gas inlet to the exhaust gas outlet through the interior of the spray column. The column with spray irrigation also has one or more spray devices that are designed to provide a flow of cleaning liquid in the interior of the spray column in a direction opposite to the total exhaust gas flow, and at least two engine exhaust gas pipes are connected with the ability to transfer fluid with the distal end of the central pipe of the exhaust gas. In addition, a method for reducing the amount of SO_x in exhaust gas is described.

EFFECT: invention reduces the amount of sulfur oxides in exhaust gas.
