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 1):
A liquid-liquid contact device 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 device comprising:\n an internal casing extending in a vertical direction and surrounding an inner chamber for providing countercurrent contact between the light liquid ascending from below and the heavy liquid descending from above; 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 from an outside of the external casing to the inner chamber; and a heavy liquid introduction tube guiding the heavy liquid from an outside of the external casing to the inner chamber, wherein the light liquid introduction tube has a light liquid ejection orifice disposed in the inner chamber, the light liquid ejection orifice allowing the light liquid guided by the light liquid introduction tube to be ejected into the inner chamber through the light liquid ejection orifice; the heavy liquid introduction tube has a heavy liquid ejection orifice disposed in the inner chamber and above the light liquid ejection orifice, the heavy liquid ejection orifice allowing the heavy liquid guided by the heavy liquid introduction tube to be ejected into the inner chamber through the heavy liquid ejection orifice; the internal casing has an upper opening and a lower opening which opens at a location below the upper opening, the upper opening allowing the light liquid having made the countercurrent contact with the heavy liquid to flow out from the inner chamber to the outer chamber through the upper opening, the lower opening allowing the heavy liquid having made the countercurrent contact with the light liquid to flow out from the inner chamber to the outer chamber through the lower opening; the external casing has a heavy liquid discharge outlet and a light liquid discharge outlet which is disposed above the heavy liquid discharge outlet, the heavy liquid discharge outlet allowing the heavy liquid to be discharged from the outer chamber through the heavy liquid discharge outlet, the light liquid discharge outlet allowing the light liquid to be discharged from the outer chamber through the light liquid discharge outlet.
