Title: Distillation apparatus and a method of distillation
IPC: C02F1/14
Filed: 1971-07-16
Abstract: 1347545 Vacuum distillation apparatus; desalination of water J G HASSLACHER 16 July 1971 [14 Aug 1970] 33447/71 Heading BIB Liquid, e.g. saline water, is submitted to distillation in frusto-conical housing 101 which is vertically divided by wall 107 into a heating compartment 105 and a distillate compartment 106, the housing being surmounted by vent 110 and being connected by conduits 117 and 119 to a valve-pump system 118 for supplying saline water to the housing, withdrawing distilled water, and discharging brine. Before a distillation operation is carried out, vent valve 111 is opened and the housing is filled with distilled water (from a previous operation) to expel all gases from the interior, whereupon valve 111 is closed. The distilled water is then drained out until the liquid-level in compartments 105 and 106 is below the top of wall 107. The interior of the housing is now under reduced pressure. The liquid in compartment 105 is set boiling by heating-coil 112 which, together with condenser coil 115, are connected to a heat-pump 114. The distillate formed on coil 115 is collected in compartment 106. Saline water is pumped to compartment 105 through conduits 121 and 117; and distilled water is withdrawn from compartment 106 through conduits 119 and 122. The heat pump 114 need not be employed; for heating and cooling may be provided by other means. For example, compartment 105 may be supplied with waste heat from a nuclear reactor, or it may be associated with a solar heater. A fan may be installed above wall 107 to increase the circulation of vapour from compartment 105 to coil 115. The housing may be made of concrete or steel. Coil 112, and other parts subject to deposition, may be coated with polytetrafluoroethylene. Buoyant and non-buoyant spheres may be provided in compartment 105 in order to prevent "bumping". Fig. 4 shows an apparatus where the feed liquid is drawn into the heating compartment through immersed nozzles 429 whereby the surface area of the boiling liquid is increased. The valves of valvepump system 118 may be controlled by electric power; and both feed and distillate compartments have indivdual monitors capable of sending out electric signals to determine the purity of the distillate. Two embodiments of valve-pump system are disclosed on Figs. 5 and 6 (not shown).

Filed: 1947-12-19
Abstract: 647,654. Separation of air. ELLIOTT CO. Dec. 19, 1947, No. 33609. Convention date, March 31. '[Class 8(ii)] A method of continuously cooling and purifying a gaseous mixture, e.g., air and of continuously cooling a compressed fluid, e.g., nitrogen comprises passing the air through a path 4 in a countercurrent heat exchanger A, passing cold nitrogen, e.g., from a rectification column 10 in the opposite direction through a path 15 in the exchanger A to condense impurities in the path 4, passing the compressed nitrogen through a path 28 in a second countercurrent exchanger B and passing cooling nitrogen, e.g., a portion of the nitrogen returning from the column 10 and warmed in a third exchanger 36 at a temperature higher than that of the air leaving the exchanger A but substantially cooler than the air entering the said exchanger, in the opposite direction through a path 50 in the exchanger B to cool the compressed nitrogen, switching the cold nitrogen flowing to the path 15 and the compressed nitrogen flowing to the path 28 so that each will flow in a reverse direction through the passage in which the other fluid was flowing and switching the air flowing to path 4 and the nitrogen flowing to path 50 so that the air will flow in reverse direction through path 50 and the nitrogen through path 4 and will sublime condensed impurities, e.g., water, carbon dioxide and ethylene in path 4. The compressed nitrogen is obtained from a compressor 22 fed by nitrogen from the warm end of exchanger A and is delivered through an after cooler 23, a line 25 and valves 71, 76 and lines 16, 27. Assuming exchanger A is to be derimed, the cold returning nitrogen and warm compressed nitrogen paths 15, 28 are first switched by closing valves 70, 76, 80, 86 and simultaneously opening valves 71, 77, 81, 87. After an interval of about one minute, to allow warming of exchanger A and cooling of .exchanger B, cold returning nitrogen is switched from path 50 to path 4 and air to be cooled and purified entering at a duct 11 is switched from path 4 to path 50 by opening valves 72, 74, 82, 84 and closing valves 73, 75, 83, 85. The cold air thus purified traverses a cold accumulator 8 and is rectified at column 10 into oxygen which leaves by a duct 60 and into nitrogen which leaves by a duct 11 where it is joined by compressed nitrogen expanded at an angle 34 to provide auxiliary refrigeration. Nitrogen from the compressor 22 is condensed in a reboiler 40 and after expansion at a valve 43 serves as reflux. In a modification an additional heat exchanger supplies additional cooled compressed nitrogen to the expander 34. In a further modification the rectification is effected in a double column and the auxiliary refrigeration is provided by expanding a portion of the air instead of nitrogen.
