摘要： There is set forth a process for the production of furnace black comprising spraying an oily carbon black forming material into a stream of hot combustion gases produced by reaction of fuel with reaction air, chilling and recovery of the carbon black by separation from the waste gases during which the reaction air is heated by means of waste gases. The waste gases are burned in a combustion apparatus by means of secondary air in order to heat the reaction air to a temperature between 600.degree. and 1,250.degree. C., preferably between 800.degree. and 1100.degree. C. and the thus heated reaction air is then introduced into the process.

摘要： In the detoxification of waste waters containing nitrite ions by means of hydrogen peroxide the addition of hydrogen peroxide is automatically controllable by adding the hydrogen peroxide continuously or in portions with continuous measurement of the pH and stopping the addition when no further reduction of the pH is caused by it. By control of the hydrogen peroxide addition through the change of the pH it is guaranteed that sufficient hydrogen peroxide is added to reach a complete detoxification of the waste water while on the other hand there is not wasted hydrogen peroxide unnecessarily.
