Removal of gas from a gas-liquid mixture flowing downward in a circular pipe was investigated using an inversely placed Y-junction. One side of the Y-junction was coated with repellent to change its wettability. The wettability of this side became poor, while that of the other side was originally good. Experiments were carried out in two conditions. Firstly, the main pipe was inclined from θ=0° to 15° for the same initial water flow rates in the branches, where θ was measured from the vertical position. Secondly, the initial water flow rates in the two branches were set to be different values for a vertical pipe. In the inclined pipe the buoyancy force acting on the gas phase played an essential role for the gas removal. On the other hand, when the initial water flow rates in the two branches were different, the inertial force of water in the branches affected significantly the gas removal.
