Abstract
A device for burning gas from a production plant for oil/gas comprising a burner at the top of a flare pipe (8). The production plant is connected to the flare pipe (8) through a low pressure collection line (1) for process gas. The device reduces combustion of valuable production gas to a minimum. To this end, the collection line (1) is connected to an expansion tank (2) having a return line (4) to the production plant and, downstream relative to the expansion tank (2), a liquid trap (6) has been disposed.
Claims6
A device for burning gas from a production plant for oil/gas, comprising a flare burner at the top of a flare pipe (8), and wherein the production plant is connected to the flare pipe (8) through a low pressure line (1) for process gas, a liquid trap (6) being positioned between said production plant and said flare pipe (8), characterized in that the collection line (1) is connected to a tank (2) adapted to accommodate a varying amount of surplus gas generated through a change in the gas volume within said collection line (1), said tank (2) having a return line (4) to the production plant, said liquid trap (6) being positioned between said tank (2) and said flare pipe (8) to block low pressure gas from reaching said flare pipe and allowing high pressure gas to pass to said flare pipe.
