Device for monitoring foam volume, flow pattern, and pressure drop in foam drainage gas recovery

Abstract

A device for monitoring foam volume, flow pattern, and pressure drop in foam drainage gas recovery includes a foam storage tank, a screw pump, valves, a gas tank, a silicon photocell board, a test pipe section, fixed pipes, reduction nipples, telescopic hoses, a color tracer injector, a differential pressure transmitter, an infrared light source, a high-speed camera, a base, rotating shafts, a waste liquid bucket, and a computer terminal and data acquisition system. The device is used to monitor the foam volume under different pipe diameters and materials, the flow pattern, and pressure drop of a flow of the mixed foam and gas. The foam volume is calculated based on light intensities of the infrared light received by the silicon photocell board and a flow velocity of the color tracer, the flow pattern is observed by the high-speed camera, and the pressure drop is measured by the differential pressure transmitter.
