| 20110132550 | Single Chamber Adsorption Concentrator - A single chamber adsorption concentrator unit is described that utilizes low grade heat to drive an adsorbent/adsorbent working pair to separate a solvent from a solute/solvent mixture. One preferred application of the device of the present invention is separating water from the salt brine produced by the aluminum smelting industry. The brine solution is introduced into a single chamber shell proximate the concentrator evaporator where the water in the brine can freely evaporate and the resulting water vapor freely flow without inhibition to be either absorbed into the adsorbent modules or condensed by the condenser. The free flow of water vapor is facilitated by continuous operation of the condenser and by maintaining the brine solution at a higher temperature than the cooling fluid driving the condenser. A mist eliminator with a wash down feature located intermediate to the evaporator and the silica gel is provided to collect contaminants that may be carried from the evaporator by the vigorous boiling. | 06-09-2011 |
