Abstract:
A liquid-liquid contact device includes: an internal casing surrounding an inner chamber for providing countercurrent contact between a light liquid and a heavy liquid; an external casing surrounding the internal casing so as to form an outer chamber around the internal casing; a light liquid introduction tube guiding the light liquid to the inner chamber; and a heavy liquid introduction tube guiding the heavy liquid to the inner chamber. The internal casing has an upper opening and a lower opening which opens at a location below the upper opening. The external casing has a heavy liquid discharge outlet through which the heavy liquid is allowed to be discharged from the outer chamber, and a light liquid discharge outlet which is disposed above the heavy liquid discharge outlet and through which the light liquid is allowed to be discharged from the outer chamber.

Claim (Index 8):
A liquid-liquid contact method which provides countercurrent contact between a light liquid and a heavy liquid which has a larger specific gravity than the light liquid, the liquid-liquid contact method comprising:\n a preparation step of preparing the liquid-liquid contact device according to  claim 1 ; an introduction step of introducing the light liquid into the inner chamber through the light liquid introduction tube and introducing the heavy liquid into the inner chamber through the heavy liquid introduction tube; a contact step of providing countercurrent contact between the light liquid and the heavy liquid by allowing the light liquid introduced into the inner chamber to ascend and allowing the heavy liquid introduced into the inner chamber to descend; a discharge step performed after the contact step, the discharge step allowing the light liquid to flow out from the inner chamber to the outer chamber through the upper opening so as to be discharged from the outer chamber through the light liquid discharge outlet, and allowing the heavy liquid to flow out from the inner chamber to the outer chamber through the lower opening so as to be discharged from the outer chamber through the heavy liquid discharge outlet; and a discharge flow rate controlling step of controlling at least one of a discharge flow rate of the light liquid discharged from the outer chamber through the light liquid discharge outlet and a discharge flow rate of the heavy liquid discharged from the outer chamber through the heavy liquid discharge outlet so as to maintain a height position of a contact interface between the light liquid and the heavy liquid within a range of between the light liquid discharge outlet and the heavy liquid discharge outlet, the contact interface being formed in the outer chamber.
