Abstract
The present invention provides techniques for recovering hydrocarbon fluids in a process flow, including recovering bitumen from a coarse tailings line. The apparatus includes a signal processor that responds to signaling containing information about the presence of a hydrocarbon fluid in a process flow; and determines corresponding signaling to control the diversion of the hydrocarbon fluid from the process flow remaining based on the signaling received. The hydrocarbon fluid may be bitumen, including bitumen flowing in a course tailings line. The signal processor receives the signaling from a velocity profile meter having sensors arranged around a circumference of a process pipe containing information about a fluid flow velocity at various levels or heights within the process pipe, including a wrap-around velocity profile meter having multiple sensing arrays located radially at a top position of 0° , a bottom position of 180°, and intermediate positions 45°, 90° and 135°.
