Client: Naval Facilities Engineering Command,
Engineering Service Center
Waste Treated: Asbestos contaminated with PCBs
Project Initiated: October, 1999
Project Completed: December 1999
Project Goal: Destroy PCBs & asbestos per TSCA regulations
The
Naval Facilities Engineering Command, through its Engineering
Service Center (ESC) and Engineering Field Activity showed
their commitment to ensure environmental excellence by funding
a demonstration of ARI's thermochemical treatment technology
(TCCT)
on asbestos contaminated with PCBs.
The
demonstration of this technology took place at the Puget
Sound Naval Shipyard (PSNS) is the result of a congressionally
mandated BAA award. ARI Technologies Inc. (ARI) of Kent,
Washington developed this technology and partnered with
PSNS to demonstrate it for the Navy.
The TCCT mobile unit used for the demonstration was contained
within two transportable trailer units, approximately 45
feet long. The operations trailer consisted of a negative
air chamber vented through HEPA filters. While a secondary
combustion chamber and afterburner were housed in a separate
trailer. This was a first generation prototype designed
to illustrate the capabilities of the mobile technology
and acquire the additional data necessary to develop and
construct modular units for nationwide implementation and
deployment. This system was designed to process up to 10
tons of ACM per day.
The
project resulted in >99.9999% destruction removal efficiency
(DRE) for PCBs and neither PCBs nor dioxin was detected
in the process effluents. The treated product was examined
using transmission electron microscopy and was found to
be 100% asbestos free. The project was closely monitored
by the US EPA who subsequently awarded ARI Technologies
a TSCA National
Operating Permit for the TCCT based upon the results
of this project.
This
project was performed on time and within the budget constraints
specified in the contract. Since the completion of this
project, the Navy has contracted with ARI for the design,
fabrication, and testing of a new, larger, modular TCCU
for deployment on DoD sites.
Another
batch of 14,000 lb. of ACM consisting of chrysotile and
amosite was brought to the system from Fort Yukon. The treatment
of this second batch of ACM was performed under a separate
contract with the Air Force Center for Environmental Excellence
(AFCEE) that was executed to take advantage of the convenience
of the system that was already in operation at PSNS. This
ACM was processed successfully along with the other ACM
that was treated at the site.
