Abstract
The present invention is a process for recovering solvent vapor which comprises absorbing solvent vapor in a first absorbing liquid, and subsequently stripping the solvent vapor to regenerate the first absorbing liquid. The stripped solvent vapor may be reabsorbed in a second absorbing liquid. The second absorbing liquid may be under greater than atmospheric pressure. Regenerating the first absorbing liquid may occur at pressures only slightly below atmospheric pressure, i.e., a low vacuum, by recycling the absorbing liquid to a regenerator. Because the regenerating process does not require the use of a high vacuum, the gas recovery apparatus may be more economically constructed and operated.
