UConn Engineering Commercialization Expert services (TCS) is performing with the Connecticut Agricultural Experiment Station, New Haven (CAES) to commercialize a know-how that will make spent emissions of a greenhouse gasoline fumigant secure to launch into the ambiance.
UConn TCS is operating to aid Connecticut’s entrepreneurial ecosystem beyond the University, by serving to non-UConn scientists, like those people at CAES, commercialize their mental assets.
Sulfuryl fluoride is a frequent fumigant used to deal with insect infestations in buildings and, progressively, generate, lumber, and other internationally transported merchandise that could be carrying invasive pests.
Sulfuryl fluoride was originally touted as an choice to methyl bromide, an ozone-depleting gasoline. Methyl bromide was formerly the common fumigant for global shipments.
“It was hailed as a fantastic substitution for methyl bromide because it was fairly powerful and it was not an ozone depleting gas,” Joe Pignatello, distinguished chief scientist emeritus at CAES, says.
Nevertheless, experts have identified that sulfuryl fluoride is a greenhouse fuel. Sulfuryl fluoride has a international warming possible (GWP) of 4780, in contrast to carbon dioxide, which has a GWP of a single. GWP is a evaluate of how much infrared thermal radiation a greenhouse gas additional to the ambiance would soak up about a presented time body, in this circumstance 100 decades.
When sulfuryl fluoride is utilized to fumigate imports, it is pumped into a huge delivery container. The sulfuryl fluoride stays in the fumigation chamber for hrs and then supporters blow it out into the ambiance.
Functioning on a U.S. Department of Agriculture-funded project, Pignatello designed a know-how that can clear sulfuryl fluoride fumes just before they are released into the atmosphere.
Alternatively than instantly releasing the gas into the environment, with Pignatello’s technological innovation, the fuel would initial go through a tube into a “spray scrubber.”
The spray scrubber is a tank loaded with liquid. The scrubber results in a mist which mixes with the incoming gas stream made up of the sulfuryl fluoride. The mist droplets have a distinctive chemical makeup that will allow them to respond with sulfuryl fluoride which cleanses the fuel stream.
“Our approach includes a one of a kind mixture of reagents that are set into the liquid of the tank and react swiftly with sulfuryl fluoride,” Pignatello states.
Then, once the fuel is “cleaned” it can be safely ventilated into the ambiance.
The wastewater can simply be treated to make it risk-free to dispose. The scrubbing procedure generates fluoride, which can be remodeled into an insoluble, harmless compound – calcium fluoride – and sulfate, which in a natural way takes place in fresh new and sea water.
“I believe the foreseeable future appears fairly great for this know-how,” Pignatello. “Because fumigators are heading to have to come across a way to reduce invested fumes from going into the environment.”
UConn TCS has assisted CAES in establishing an unique possibility arrangement with a non-public enterprise to commercialize this patent-pending engineering.
This partnership, facilitated by TCS, serves as the first of ideally more such commercialization engagements the UConn workplace will facilitate for its external exploration companions.
“This is just 1 of quite a few strategies that UConn is increasing the innovation ecosystem in Connecticut and further than,” Christopher Conners, TCS licensing director for lifetime sciences, states.
