Client #299

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

Product Use:

All products have aerospace applications

Trial Number	Date Run	Purpose	Success Rating
0	04/02/2008	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	05/01/2008	To evaluate possible immersion cleaning process for company to replace current solvent dunking system.	A follow up test, usually based on company input.
2	05/01/2008	To evaluate selected products on second supplied cutting fluid using simulated cleaning process.	A follow up test, usually based on company input.
3	05/01/2008	To evaluate selected products on third supplied metal working fluid using simulated cleaning process	A follow up test, usually based on company input.
4	05/20/2008	To evaluate additional products for first supplied soil.	A follow up test, usually based on company input.
5	05/20/2008	To evaluate additional products for second supplied soil.	A follow up test, usually based on company input.
6	05/20/2008	To evaluate additional products on third supplied metal working fluid	A follow up test, usually based on company input.
7	05/21/2008	To evaluate products at higher concentrations and longer times on grinding fluid.	A follow up test, usually based on company input.
8	05/21/2008	To evaluate products at higher concentrations and longer times on cutting fluid.	A follow up test, usually based on company input.
9	04/19/2008	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	07/02/2008	To conduct on-site assistance for replacing TCE and nPB in cleaning operations.	Technology Transfer.
11	08/07/2008	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	08/07/2008	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	08/07/2008	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	08/08/2008	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.
