The document discusses vacuum distillation, which is a process used to purify aluminum cold rolling oil. It describes Filtertech, Inc., which manufactures vacuum distillation units (VDUs) for purifying used rolling oil. Key details include: - Vacuum distillation lowers the boiling point of oil, allowing purification to occur at a lower temperature and with less energy. - A VDU operates in three cycles to purify used rolling oil through distillation under vacuum pressure. - Utilities like electricity, cooling water, and chilled water are required to operate a 100 gallon per hour VDU. - Tests show vacuum distillation effectively separates contaminants from used oil. - A 100 GPH

• The purpose of vacuum distillation

8. What is distillation:
• Distillation is the process of evaporating a liquid,
then cooling the vapors to condense and collect
them
• The purpose is to purify the liquid leaving behind
all the other contaminants
• The distillation as a purifying method is based on
the difference of the boiling points of the oil or
liquid to be distilled from that of the
contaminants.

9. Vacuum Distillation:
• Distillation under reduced pressure to below
atmospheric pressure is called vacuum
distillation.
• The boiling point of the liquid will decrease as the
pressure decreases. The lower the pressure or
(the higher the vacuum) the lower the boiling
point.
• Lowering the boiling point reduces the heat of
vaporization or the amount of energy needed to
purify the desired liquid
