Patent no. RO 119629 B1/28.01.2005
The patent presents a new method for selective separation of
carboxylic acids (among them the citric acid being the most
Description important) from citric fermentation broths. The method consists
EN on reactive extraction and increases the separation efficiency,
decreases the required steps number and, implicitly, reduces the
separation cost.

extractia reactiva, mareste eficienta separarii, reduce numarul de
etape necesare purificarii si, implicit, reduce costurile separarii.

Patent no. RO 119690 B1/28.02.2005
Description
EN
The equipment could be used for separation of the bioactive
compounds, with pronounced chemical and thermal lability, by
extraction and transport through liquid membranes, without or with
addition of a carrier (free or facilitated pertraction). This equipment
does not require the use of tensides for stabilizing the liquid
membrane, thus increasing the purity of the pertracted compounds.
