A distillation apparatus and method of more rapidly purifying water, potable spirits and essential oils and more specifically to a unique heat distribution device referred to herein as the flame flow that provides for the contents of the apparatus to reach evaporation temperatures more quickly and maintain temperature to provide better control and more evenly heat the contents of a distillation apparatus.

The invention relates to a method and a device for cleaning contaminated used oil, in which starting material is heated to the gas phase and the resultant vapor is rectified, with purified oil being removed as condensate from a drain in a rectification column. This enables efficient operation even in the smallest of systems, such that a compact system configuration and thus in particular mobile use by a container structure is made possible. The invention also reduces the cost required for servicing. The used oil is subjected to an evaporation process by at least indirectly placing the starting material in contact with a melting bath, the melting temperature of which is above the evaporation temperature but below the ignition temperature of the used oil, and by rectifying the vapor in the rectification column.

A distillation device may comprise a source fluid input and an evaporator in fluid communication therewith. The device may further comprise a compressor having an impeller coupled to a motor, the compressor having a low pressure inlet for vapor from the evaporator and a high pressure outlet for compressed vapor. The device may further comprise at least one temperature sensor configured to monitor temperature of vapor in the inlet and a condenser in heat transfer relationship with exterior surfaces of the evaporator and in fluid communication with the compressor outlet. The device may further comprise a controller configured to govern rotation speed of the impeller with an impeller motor command based on a calibrated motor speed for the distillation device. The controller may be configured to determine an adjusted motor speed for a next use of the device and overwrite the calibrated motor speed with the adjusted motor speed.
