We propose a new injection process of CO_2 using the static mixer for the CO_2 disposal into the intermediate ocean. Liquid CO_2 is released into the ocean after there are agitated with seawater flow in the mixer. Laboratory scale equipment was made to investigate the properties of the static mixer. The drop distribution came to be uniform with the static mixer. The size of drop became small dramatically, and the size was controllable with the water and the CO_2 flow velocity. Under a suitable condition, the formation of CO_2 hydrate was observed without the blockage of the pipe and thus, the CO_2 may be able to release as the hydrate in the ocean by this process. Since the behavior of the CO_2 drops and hydrates released into ocean is determined by its initial size, the injection process using the static mixer is a controllable method of an environmental effect in the ocean.
