Abstract:
An autonomous system for collecting fugitive emissions resulting from bubbles bursting on the top surface of a liquid contained in a vessel open to the atmosphere, the perimeter of said vessel consisting of at least a front and a back portion, comprising:a liquid distribution apparatus suspended in said liquid at a pre-specified depth and located adjacent at least part of the inside perimeter of said vessel, said apparatus comprising at least one pipe and pipe connections assembled to permit a distribution of at least a portion of said liquid near said surface, said distribution initiated along said front portion and oriented toward said back portion, said apparatus further assembled to collect at least a portion of said liquid along said back portion, wherein said pipe and pipe connections are connected to at least one pump in such a manner as to effect a system for circulating said liquid in said vessel, and wherein said apparatus establishes a flow along said top surface from said front portion to said back portion such that said bubbles are pushed to an area near said back portion; and flotation support for said liquid distribution apparatus, wherein said support enables said apparatus to maintain a constant orientation with respect to said top surface.
