The Wipe Solvent Program: Delivery Order 0005: Fluids, Lubricants, and Related Materials
Abstract
Freon 113 TF(Registered) solvent, 1,1,2 -trichloroethane (Freon 113(Registered)) was widely used to clean equipment. With the banning of many halogenated solvents due to ozone depleting tendencies, users desperately sought substitute environmentally friendly solvents. In many cases, the substitutes did not work as well and had other issues that made them less than ideal. Often, it was difficult to assess various solvents based on the manufacturers' claims. In this work, which was directed to the development of replacement solvents for wipe and liquid cleaning of liquid and gaseous oxygen systems, the authors evaluated seven solvents, plus Freon 113 as a baseline, that were advocated as Freon 113 replacements. First, the cleaning ability was evaluated on oxygen system components. These solvents were also tested for compatibility with oxygen systems using the Liquid Oxygen Mechanical Impact Test and by determining the Autogenous Ignition Temperature in pure oxygen. In addition, elastomers seals Nitrile, Silicone, Viton A, Buna N, polytetrafluoroethylene, and Kel F were evaluated with the solvents. Elastomer damage on prolonged contact with most solvents was similar to Freon 113(Registered). No single solvent performed as well as nor as universally as did Freon 113(Registered), but some were close.
