Formation experiments Of CO2 hydrate from the two-phase flow of liquid CO2 and water were carried out using static mixers with different types of mixing elements to elucidate the effects of mixing functions of the static mixer on CO2 hydrate forma...
Process design for a new injection method of liquid CO2 using a static mixer was conducted based on laboratory experimental results on the formation process of liquid CO2 drops covered with hydrate film by a Kenics-type static mixer, and numerical...

FLUID PHASE EQUILIBRIA 230(1-2) 90-98 2005年3月
A method for determining quadruple points of a two-component system containing a simple hydrate phase is proposed. This method utilizes the quasi-static change of the system along three-phase equilibrium lines and was proved to be able to determin...
