Abstract
Un concentratore di liquidi. L'invenzione prevede un'asta di guida (1) attorno alla quale una soluzione fluisce in una camera (2). Una sorgente di calore (3) circonda l'asta di guida. La soluzione è preferibilmente mescolata con un solvente di scambio, il solvente di scambio avendo un punto di ebollizione più alto di quello dei solventi della soluzione. Quando il miscuglio fluisce verso il basso lungo l'asta di guida, i solventi originali vengono preferibilmente evaporati, concentrando i materiali di interesse, e lasciando l'effluente relativamente più concentrato nel solvente di scambio.
