Providence Photonics Inc. in Baton Rouge has received a $299,877 federal grant as it continues to develop technology to measure how effectively industrial flares burn unused hydrocarbons and other chemical waste.

Providence is one of nine companies awarded Small Business Innovation Research grants this week totaling nearly $3 million.

The technology Providence is developing uses multispectral, infrared imaging to provide real-time measurements of concentrations of carbon dioxide, carbon monoxide and hydrocarbons in industrial flare plumes.

Like exhaust from vehicles, unburned industrial emissions contribute to the formation of ozone — or smog — in the presence of sunlight.

The system Providence is working on would also make automated adjustments to more completely burn chemicals before they are released into the open air.
