The MiniProCycler relies on its high efficiency distillation columns to remove unwanted contaminants from xylene, alcohol and xylene substitutes. For xylene the contaminants are mostly alcohol, biological materials and paraffin. The contaminating alcohol is distilled into a waste container and the pure xylene is distilled into a separate container. Paraffin and biological materials remain behind in the boiler and are removed through a drain. Recycling xylene substitutes follows the same procedure except that xylene substitutes have a higher boiling point then xylene.
Recycling alcohol presents different challenges then xylene. The main contaminants in alcohol are water, biological material, fat, protein and stain. Purified alcohol is distilled over into a receiver. Water and all the other contaminants are left behind in the boiler and are removed through a drain.
