Abstract
In this paper, the results of industrial tests of a new triangular attachment with cross-holes for cleaning coke oven gas from dust, carbon dioxide and formaldehyde vapours are given. According to these data, comparative diagrams and regression charts are constructed. The paper considers the results of own experiments, which compared with the results of other scientists and various statistical data. For comparison, a wooden chord attachment and the most effective Rashig ring attachment are used. The results of the tests coincide with the theoretical calculations and confirm the effectiveness of the new attachment. The efficiency of the new attachment is proven for the purification of coke oven gas from CO2 (carbon dioxide), CH2O (formaldehyde vapours) and dust. The new attachment improves the cleaning by 25 % with respect to the wooden chord (its prototype) and by 15 % compared to the Raschig rings, which are one of the most effective attachments, and close to the material for the new one. It is proved that the optimum temperature for all types of impurities is 15 °C
