Smoke plume? Sometimes unavoidable

Sometimes a colored plume of smoke above Chemelot is visible in connection with the shutdown or the start-up of a factory at Chemelot.

This smoke plume is prevented during normal operation. When stopping an installation, the temperature drops and not all vapors are captured.

And at start-up, the installation must come to temperature in order to function properly. The smoke plume for a limited time is therefore unavoidable.
