Project Number 1



Summary: A drop in solvent was evaluated as a quick fix to the client’s use of TCE. Follow up on-site visit by SSL revealed additional opportunities to reduce the use of hazardous materials by replacing manual cleaning in buckets located throughout the facility.

Test Objective: To replace TCE with a non-toxic chemical

Problems with Current Method: No except uses TCE

Purpose of Cleaning: Customer requirement to have part cleaned and /or passivated

Product Use: All products have aerospace applications

Cleaning Chemicals: Trichloroethylene

Trial Number Date Run Purpose Success Rating
0 04/02/08 To evaluate selected nPB alternatives for drop-in replacement to TCE for removing oil and grease from various metals. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
1 05/01/08 To evaluate possible immersion cleaning process for company to replace current solvent dunking system. A follow up test, usually based on company input. 
2 05/01/08 To evaluate selected products on second supplied cutting fluid using simulated cleaning process. A follow up test, usually based on company input. 
3 05/01/08 To evaluate selected products on third supplied metal working fluid using simulated cleaning process A follow up test, usually based on company input. 
4 05/20/08 To evaluate additional products for first supplied soil. A follow up test, usually based on company input. 
5 05/20/08 To evaluate additional products for second supplied soil. A follow up test, usually based on company input. 
6 05/20/08 To evaluate additional products on third supplied metal working fluid A follow up test, usually based on company input. 
7 05/21/08 To evaluate products at higher concentrations and longer times on grinding fluid. A follow up test, usually based on company input. 
8 05/21/08 To evaluate products at higher concentrations and longer times on cutting fluid. A follow up test, usually based on company input. 
9 04/19/08 To conduct walk through of facility and collect samples to assist in changing out of TCE to avoid EPA regulations and paperwork Technology Transfer. 
10 07/02/08 To conduct on-site assistance for replacing TCE and nPB in cleaning operations. Technology Transfer. 
11 08/07/08 To evaluate aqueous alternatives using ultrasonic cleaning Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
12 08/07/08 To evaluate aqueous alternatives using ultrasonic energy on second supplied contaminant. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
13 08/07/08 To evaluate aqueous alternatives on grinding fluid using ultrasonic energy Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
14 08/08/08 To evaluate aqueous alternatives on supplied lubricant using ultrasonic cleaning. Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
