System and method for remediation of explosive contamination using convective heat
First Claim
Patent Images
1. A system comprising:
- a conduit or vessel comprising an internal surface including a residual explosive material deposited in or on the internal surface; and
a heated gas flow source in fluid communication with the internal surface, wherein the residual explosive material has a break down temperature and the heated gas flow source is adapted to produce a flow of heated gas into the sewer line sufficient to heat the internal surface to a temperature at or in excess of the break down temperature.

Abstract
According to the present teachings, a system and method are provided for decontaminating a conduit or vessel contaminated with residual explosive material. The system can include a heated gas flow source for heating a gas and providing a flow of the heated gas into the interior of a conduit or vessel. The temperature of the heated flow of gas can be at or in excess of the break down temperature of the residual explosive material.

16. A method comprising:
-
connecting a heated gas flow source to a conduit or vessel, the conduit or vessel including an internal surface and comprising residual explosive material deposited in or on the internal surface, the residual explosive material having a break down temperature at which the residual explosive material chemically breaks down;
introducing a heated gas flow into the conduit or vessel; and
maintaining a heated gas flow into the conduit or vessel at least until the temperature of the internal surface reaches a temperature at or in excess of the break down temperature. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method, comprising:
-
providing a heated gas flow at an initial temperature to a conduit or vessel that comprises an inlet, an outlet, and an internal surface, the internal surface comprising residual explosive material having a break down temperature, deposited at least therein or thereon, the internal surface being in fluid communication with the heated gas flow; and
maintaining the heated gas flow at or above the initial temperature at least until the temperature of the heated gas flow at the outlet is at or above the break down temperature of the residual explosive material. - View Dependent Claims (25, 26)
