Redditor Arana Discoteca recently shared this photo of oil refinery flares burning into the skies over in Beaumont, Texas. This happens whenever there is a power outage or some other kind of disruption to the normal flow of operations at a refinery. In this case it was a power outage.
Beaumont is one of the towns listed on an article I wrote a couple of years ago about neighborhoods located near refineries. The photo above was not taken at some distant isolated refinery; there are people living directly across the street from the Beaumont refineries.
