Abstract
It is common practice to discharge waste vapors from certain chemical processes into the atmosphere. Many of these vapors, usually referred to as 'vent gases', contain compounds which are considered to be pollutants in the atmosphere. In this invention the vent gases are oxidized in the combustion chamber of a Diesel engine before release to the atmosphere. The oxidation step reduces the concentration of noxious compounds in the vapor to a level acceptable for atmospheric discharge.
