Reaction of mercury with sulfur in a liquid-liquid reaction to form mercury sulfide comprises providing liquid sulfur and mercury and converting to mercuric sulfide, collecting mercury sulfide by separating from excess sulfur

摘要

Reaction of mercury with sulfur in a liquid-liquid reaction to form mercury sulfide comprises (a) providing liquid sulfur in a container (2), (b) supplying the liquid sulfur through a supply line (3) vertically to the bottom of a counter current reactor (1), (c) providing mercury to the vertically upper end of the counter current reactor, where the mercury in the counter current reactor falls downwards through the liquid sulfur at 120?C-150?C and converting to mercuric sulfide, (d) collecting the resulting mercury sulfide and (e) separating the mercury sulfide from excess sulfur. Reaction of mercury with sulfur in a liquid-liquid reaction to form mercury sulfide comprises (a) providing liquid sulfur at 120?C-150?C in a container (2), (b) supplying the liquid sulfur through a supply line (3) vertically to the bottom of a counter current reactor (1), where the liquid sulfur in the counter current reactor is guided vertically upward and is recycled in a circulation at the vertically upper region of the countercurrent reactor through a discharge pipe (4) to the container, (c) providing mercury to the vertically upper end of the counter current reactor, where the mercury in the counter current reactor falls downwards through the liquid sulfur at 120?C-150?C and converting to mercuric sulfide, (d) collecting the resulting mercury sulfide at the vertically lower end of the countercurrent reactor and (e) separating the mercury sulfide from excess sulfur. An independent claim is also included for a plant for performing the above method, comprising a vertically oriented countercurrent reactor, a container for liquid sulfur, which is connected to the vertically lower end of the countercurrent reactor through a supply line, where a pump (7) for conveying the liquid sulfur is arranged in the supply line, a discharge pipe (4) for reconducting the liquid sulfur into the container, which is arranged in the vertically upper region of the countercurrent reactor, and a feed device for the mercury, which is arranged on the vertically upper end of the countercurrent reactor.
