Mixing liquid extraction apparatus and mixing liquid density measuring device

摘要

PROBLEM TO BE SOLVED: To provide an apparatus capable of properly extracting a mixed liquid from a multiphase flow, and to provide a device for measuring a mixed liquid density including the same.;SOLUTION: The apparatus has an orifice, a pair of communication pipe 13, a gas-liquid extraction tank 14, a liquid-gas discharge pipe 15, a liquid pool tank 17, a liquid flow rate control valves 18, 19. The difference in pressure between pressures of before and behind an orifice is periodically changed by the flowing of a slug flow in a pipeline. Therewith, the pair of communication pipe 13 and the gas-liquid extraction tank 14 extract the gas-liquid and discharge the gas mainly simultaneously. In the gas-liquid extraction tank 14, the gas-liquid is forcibly swayed in the right and left direction and in the vertical direction and agitated, and then the gas with the liquid is discharged. Thus, the gas-liquid with a high ratio in liquid phase remains in the gas-liquid tank 14. Then, a mixed liquid is extracted by removing the gas from the gas-liquid with the high ratio in gas-liquid phase and is collected in the liquid pool tank 17.;COPYRIGHT: (C)2008,JPO&INPIT
