To eliminate the use of N-Propyl Bromide in cleaning operations
Date Run:
04/11/2016
Experiment Procedure:
Stainless steel coupons were weighed to determine the initial weights. The bottom third of the coupons were soiled with Sonnen B-200L oil using a swab. Three coupons were immersed at room temperature in the Fluosolv CX, the other remaining coupons were immersed at room temperature DuPont Vertrel SION. Each set of coupons were cleaned for five minutes each. Once the coupons were removed from the cleaner, the coupons were hung to air dry fifteen minutes. The coupons were reweighed, and percentage calculations were completed.
Trial Results:
The Fluosolv CX was inefficient at removing the Sonnen B-200L oil from the stainless-steel coupons, with an average percentage removal of 61.48%. However, the DuPont Vertrel SION was very efficient at removing the Sonnen B-200L oil, its average removal rate was 98.86%.
