Low flow fluid separator

A passive separator for separating at least a first fluid having a first density from a second fluid having a second density greater than said first density comprising:

• a first chamber;
• a second chamber;
• a conduit extending through said first chamber from a fluid inlet on a first side of said chamber and terminating near a second side of said first chamber;
• said second chamber being located on top of said first chamber;
• said first chamber having an opening on an upper side thru which fluids may flow upward into an enclosed passageway and into said second chamber;
• an outlet atop of said enclosed passageway for collecting a first fraction of said first fluid from said enclosed passageway and a second fraction of said first fluid from said second chamber;
• said second chamber including a stack of fluid separator plates;
• the said upper side of said first chamber being substantially flat and being inclined slightly to horizontal and a substantially flat upper side of said second chamber being slightly inclined to horizontal to facilitate the flow of said first fluid to said outlet, from said first chamber and from said stack plates in said second chamber.
