Abstract
An energy saving process for recovery of solvent from
a solvent-oil mixture in a staged series of vaporization
zones at progressively increasing pressure in which exter
nal heat is supplied to the vaporization stage having the
highest pressure and heat for each preceding vaporization
stage is supplied by heat exchange with vapors from suc
ceeding vaporization stages with vaporization at the lowest
pressure stage carried out in a plurality of vaporization
zones at substantially equal pressure.
