ABSTRACT
Where low-cost chlorinated solvents either cannot be used or are not a good choice, there are new so-called exotic solvent and solvent blends to choose from. One of the common threads among many of these newer solvents is cost. ¤ey are expensive per pound, per gallon, or per drum. ¤ey are so expensive, costing perhaps $10,000-$15,000/drum, that unnecessary solvent losses are worth preventing. Proper operating procedure, combined with a decent retro©t, can produce operating costs on a par with the older solvents.
