Abstract
An apparatus and method for recovering two immiscible fluids in a vapor generating and recovery apparatus wherein water, an immiscible cleaning solvent, and an emuslifying agent are subjected to sufficient heat in a first chamber to vaporize the water and the immiscible solvent and then condense in a second chamber the water and immiscible solvent, returning in separate streams the water and solvent to the first chamber.
Claims12
A vapor generating and recovery apparatus comprising:
- a housing having a vaporizing chamber and a condensing chamber therein separated by a first weir of preselected height;
- means to add heat to said vaporizing chamber and means to remove heat from said condensing chamber;
- and,
- means to transfer condensate from said condensing chamber, to said vaporizing chamber, said means to transfer condensate including means to separate components within the condensate and return said separated components in separate streams to said vaporizing chamber, said means to remove heat being disposed within said condensing chamber below the upper extremity of said weir and spaced sufficiently above said means to transfer condensate for providing a constant vapor blanket over the means to remove heat from the condensing chamber.
1 more element
A vapor generating and recovery apparatus comprising:
- a housing having a vaporizing chamber sub-divided into a plurality of sub-chambers by weirs of preselected height, and a condensing chamber separated from said vaporizing chamber by a first weir of a preselected height greater than that of any said weirs sub-dividing said vaporizing chamber;
- means to add heat to at least one of said sub-chambers of said vaporizing chamber, and means to remove heat from said condensing chamber;
- means to transfer condensate from said condensing chamber to at least one of said vaporizing sub-chambers, said transfer means including means to separate components within the condensate and in returning at least one of said separated components to at least one of said vaporizing sub-chambers, said means to remove heat being disposed within said condensing chamber below the upper extremity of said weir.
