Patent no. RO 119629 B1/28.01.2005<br />
The patent presents a new method for selective separation of<br />
carboxylic acids (among them the citric acid being the most<br />
Description important) from citric fermentation broths. The method consists<br />
EN on reactive extraction and increases the separation efficiency,<br />
decreases the required steps number and, implicitly, reduces the<br />
separation cost.<br />
Inventia se refera la un procedeu nou se separare selectiva a<br />
acizilor carboxilici (dintre care cel mai important este acidul<br />
Descriere<br />
citric) din lichidele de fermentatie. Aceste procedeu, bazat pe<br />
RO<br />
extractia reactiva, mareste eficienta separarii, reduce numarul de<br />
etape necesare purificarii si, implicit, reduce costurile separarii.<br />

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