Abstract
Abstract An apparatus for vaporizing and recovering, by condensation, a composite mixture of at least two components, at least one of which is a liquid. The apparatus includes at least one chamber in which the mixture is brought to boiling and includes means to condense the vaporized portion of the mixtures. A liquid of the mixture in the vaporizing chamber is vaporized by heating coils and subjected to circulation to uniformly disperse the mixture. The apparatus may further include a system for continuously filtering the mixture in the vaporizing chamber to remove undesirable particulates, a mixture spray device for spraying the mixture into the vaporizing chamber, and an ultrasonic vibrating means.
