Abstract
Provided is a backflow collection system that includes a collection vessel having an upper section and a lower section, the collection vessel having a side opening configured to receive backflow from an oil/gas well, as well as a discharge port proximate an upper end of the upper section configured to discharge pressurized gas from the collection vessel. The backflow collection system may further include an auger coupled proximate the lower section of the collection vessel, the auger configured to receive solid and liquid matter from a bottom opening in the lower section, and when elevated remove at least a portion of the solid and liquid matter from the collection vessel, the collection vessel designed such that when fluid is contained therein it acts as a liquid/gas seal to prevent the pressurized gas from exiting through the bottom opening in the lower section of the collection vessel.
