A mobile treatment system that destroys chemical warfare agents without producing hazardous waste has been announced by Southwest Research Institute.

The system it helped develop comes in two configurations, one wet and one dry.

The dry pollution control process, suited for arid or remote regions, uses a Dedicated EGR engine thermal destruction device developed by Southwest Research Institute for the Agnostic Compact Demilitarization of Chemical Agents program of the U.S. Defense Advanced Research Projets Agency. When chemicals are destroyed, exhaust gases pass through a fluidized bed where the combusted byproducts are captured.

SwRI said the used soil remains non-hazardous.

A wet pollution system, developed by a Canadian company, has a stand-alone plasma torch treatment device with a liquid scrubber system.

"It is in our national interest to have a field-operable unit that can safely dispose of chemical warfare agents and other dangerous chemicals on the front lines in a timely manner," said Darrel Johnston, a senior program manager in SwRI's Chemistry and Chemical Engineering Division. "We began development of the soil scrubber system in June 2016 and delivered a proof-of-concept system (to DARPA) in February 2017."

SwRI said the system is modular and fit into a large shipping container.

Both wet and dry configurations have undergone initial testing in Canada. The dry soil-based scrubber was interfaced with the Canadian company's plasma torch front end and proved more than 99.9999 percent effective in destroying simulated chemical weapon agents.

According to the Texas-based institute, the system is scheduled for testing with authentic chemical agents this summer.

IS attacked Iraq forces with chemical weapons: military
Baghdad (AFP) April 16, 2017
The Islamic State group used chemical weapons against Iraqi forces taking part in the operation to recapture Mosul, injuring some security personnel, the military said on Sunday. IS has periodically carried out attacks using chemical weapons, but both the toll and the impact on military operations has been minimal and the jihadists' bombs and bullets are far deadlier. "The Daesh terroris ... read more
