Process and apparatus for breaking liquid membrane emulsions from metal extraction processes

摘要

The invention relates to a process and an apparatus for breaking liquid membrane emulsions from extraction processes by applying an electrical field, the emulsion being broken in a vertical breaking reactor and then the phases being separated in a separately arranged gravity settler, in which case residual emulsion can be taken off and returned to the breaking reactor. The apparatus comprises an emulsion breaker having plate electrodes and feeds and outlets for the emulsion to be broken and a settling region, the emulsion breaker being spatially separated from the settling vessel.
