ABSTRACT:
A method to condense or coalesce matter is carried out by providing a suitable, narrow passageway for throughput of matter in a vapor state, and passing the matter in a vapor state through said passageway, under conditions such that the matter is coalesced into a more ordered state. Also, a matter coalescing apparatus has a hollow housing in communication with at least one of--(A) a plurality of suitably narrow hollow passageways and (B) a suitably narrow, elongately hollow, matter-coalescing passageway--for throughput of matter to include as a vapor therein. Consequently, highly efficient yields of coalesced matter, to include liquid coalesced from vapor, even under only mild vacuum or at about ambient atmospheric pressure can be obtained. This is especially so with respect to oils, where yields as high as 95 percent or greater can be provided hereby. The invention can be practiced under such outstanding yield efficiencies without a general need for significant external cooling.
