Contaminated barrel cleaning method - evacuates barrels in vacuum stove while heating and rotating

摘要

The method cleans used and contaminated barrels without harming the environment. The barrels (8) are evacuated in a vacuum stove (1) while being rotated and fully heated. Heating can be by eddy currents and before rotating and evacuation to extract trapped air and gas. Rotation is between 20 and 60 rpm, with the barrels horizontal. The gases are passed through a condenser in the vacuum pipe, and then through an atmospheric one.
