Abstract
A vacuum dehydrator for processing an oil containing entrained contaminants such as water, air, and particulates comprises a tower enclosing upper and lower chambers. A random packing is contained in the upper chamber. The oil is preheated to a temperature above the boiling point of water and is introduced into the upper chamber for downward flow through the random packing into the lower chamber. Entrained air and water is retained as water vapor in the upper chamber, and particulates are retained in the random packing. Heated ambient air is introduced into the lower chamber for upward flow through the random packing into the upper chamber, and the upper chamber is cooled to condense the water vapor. Oil and condensed water are pumped respectively from the lower and upper chambers.
