In the extruding, cooling, pelletizing, drying, and storing of ethylene polymers prepared by a high pressure continuous mass process, air coming in contact with the polymer and the cooling water is diluted with low concentrations of ethylene gas. This dilute air-ethylene mixture is drawn into an air stream fed to a flare stack gas burner as a component of the oxidizing gas to avoid release of the ethylene to the atmosphere.
