Alcohol
Case Studies
Martin Marietta Astronautics has substituted an IPA spray for CFC-113 in the second stage of a two-step
cleaning process. The old system had required the purchase of 55,000 lb of CFC-113 annually, which was released
to atmosphere. The IPA spray system has an inert atmosphere, solvent recovery, and VOC emission controls.
Capital expenditure was $1,300,000. The savings realized amount to $325,000 per year with zero CFC-113
emissions.
