Liquid entrainment in gas at high pressure - Part 1: Experimental approach and initial testing

摘要

An experimental program for measuring the fraction of liquid entrained in the gas stream through a horizontal 3-inch pipe has been conducted. A customized test section was designed and fabricated for this testing, including an isokinetic sampling system designed for pressures up to 3,600 psi to measure the liquid entrained in the gas phase. Two sets of tests were conducted one with an oil-nitrogen mixture and another with oil-methane. During the testing, the pressure was varied between 500 psig and 1,200 psig. The superficial gas velocity was varied between 2 m/s and 17 m/s, while the superficial liquid velocities varied from 0.005 m/s to 0.1 m/s. Flow visualization at high-pressure was also conducted to verify the flow pattern at high-pressure.
