A nozzle for spouting a liquid phase, in which one liquid phase in a two-liquid phase system can be stably jetted as highly dispersible droplets while suppressing coalescence of droplets, and accumulation of fine solid components in the nozzle hardly occurs. The nozzle has a structure in which capillary tubes or pores are assembled. Further, the capillary tubes or the pores are formed using a suitable material having a low affinity for organic or a low affinity for water, or a material subjected to appropriate surface treatment.

Nozzle for liquid phase ejection

A new system in which a forward extraction part, a scrubbing part, and a backward extraction part operate together and synchronously to produce specific substances by extraction and separation in a liquid-liquid system. The aqueous phase is circulated independently only in the forward extraction part one or more times, and the organic phase is circulated from the forward extraction part through the scrubbing part and the backward extraction part to the forward extraction part again in synchronization with the liquid circulation of the aqueous phase.

Method and apparatus for producing specific substances by extraction and separation in a liquid-liquid system

The particle components may be collected by using a phenomenon that the particle components in the aqueous phase aggregate at the liquid-to-liquid interface. Both of the particle components and the dissolved components in the aqueous phase may be simultaneously collected if combined with liquid-liquid extraction phenomenon that the dissolved components in the aqueous phase are collected into the solvent phase through the liquid-to-liquid interface. The aggregation phenomenon of the particle components at the liquid-to-liquid interface may be promoted by using an emulsion flow method, a method of applying mechanical external forces (such as stirring and vibrating) or another method combining both the above-mentioned methods.
