Method and an apparatus for separation of azeotropic mixtures by distillation using salt effect
Abstract
Abstract COLLECTED AS THE DISTILLATES FROM THE FIRST AND SECOND FRACTIONATING TOWERS, RESPECTIVELY. AZEOTROPIC BINARY SOLUTIONS ARE FRACTIONATED BY MEANS OF AN EVAPORATOR, AND IN SOME INSTANCES ALSO A CONCENTRATOR, IN CONJUNCTION WITH TWO FRACTIONATING TOWERS. THE DISTILLATE OR THE BOTTOM LIQUID FROM THE FIRST FRACTIONATING TOWER IS FED TO THE EVAPORATOR TO WHICH IS CHARGED A SALT WHICH CHANGES THE RELATIVE VOLATILITIES OF THE SOLUTION COMPONENTS. VAPOR GENERATED IN THE EVAPORATOR IS FED TO THE SECOND FRACTIONATING TOWER. IN THE CASE OF A MINIMUM BOILING AZEOTROPE, THE LOWER BOINING COMPONENT BECOMES THE BOTTOM LIQUID OF THE SECOND FRACTIONATING TOWER AND, THUS, MAY BE COLLECTED AND THE HIGHER BOILING COMPONENT BECOMES THE BOTTOM LIQUID OF THE FIRST FRACTIONATING TOWER OR THE BOTTOM LIQUID OF THE FIRST FRACTIONATING TOWER IS A SOLUTION OF THE SALT IN THE HIGHER BOILING COMPONENT FROM WHICH THE HIGHER BOILING COMPONENT MAY BE SEPARATED BY MEANS OF A CONCENTRATOR. WITH A MAXIMUM BOILING AZEOTROPE, THE HIGHER AND LOWER BOILING COMPONENTS ARE
