The Effect of Surfactants on Characteristics of Hydrodynamic and Mass Transfer Coefficient in Gas-Liquid Dispersion Column [PDF]
Engineering and Technology Journal, 2007 This work studis the effect of liquid properties (water, solution 0.2-1.5 wt% for each of i-propanol, and n-butanol), temperature (26-55 oC) andsuperficial air velocity (1-15cm/s) on the gas holdup and mass transfercoefficient in air-liquid dispersion ...

Study on Optical Fiber Gas-Holdup Meter Signal Denoising Using Improved Threshold Wavelet Transform
IEEE Access, 2023 The optical fiber probe gas-holdup meter is a new logging tool, which can be used to measure the gas-holdup of oil-gas-water three-phase flow during production logging.

Contractual Holdup and Legal Intervention [PDF]
, 2007 This article develops the point that incentive and risk-bearing problems associated with contractual holdup may justify legal intervention. Contractual holdup is considered both for fresh contracts and for modifications of contracts.
