Abstract: The residual gases obtained in the production of cyanuric chloride having a pressure of 1-5 bar (absolute) preferably 1-4 bar, are worked up by leading them into the lower portion of a column, reacted in the column with at least the equivalent amount of hydrogen cyanide to form cyanogen chloride and led in countercurrent flow to the water charged to the upper portion of the column whereupon the aqueous solution of cyanogen chloride formed is withdrawn from the lower portion of the column and preferably is returned into the production portion of the plant for recovery of the cyanogen chloride while the purified waste gas of the column leaves in the upper portion of the column.

Abstract: The present invention provides a process for treating the residual gas obtained in the production of cyanuric chloride, in which residual gas is fed into the lower end of a column at a pressure of 1 to 5 bars (absolute), said gas is reacted in the column with at the least the equivalent amount of hydrogen cyanide for the formation of cyanogen chloride, said gas being passed in counterflow to water charged in the upper end of the column, the aqueous solution of cyanogen chloride thus formed being drawn off from the lower end of the column and the purified waste gas leaving the upper end of the column.
