Abstract
The invention relates to a method for thermally after-burning the waste gas flows developing during the production of acrolein in a gas phase process and for thermally after-burning the waste gas flows developing during the production of hydrocyanic acid in a gas phase process, characterized in that the waste gas flows from the production of acrolein and the waste gas flows from the production of hydrocyanic acid are supplied to a joint thermal after-burning process.
