Pressure gradients seem to be affected most when gap bridging by waves is occurring. 2 INTRODUCTION Liquid loading is a well-known problem that occurs when wet gas...

Abstract This paper examines the critical flow rates of gas and liquid necessary to keep particles moving in a horizontal flow line with emphasis on flows with high gas-liquid ratios resulting in stratified flow with small liquid hold-up. Experimental results are presented for flows in 0.05 m...

The splitting could be controlled by either partly closing the top valves at the riser top or the two valves at the riser base. At low flow rates one riser...
