摘要： A dry condenser which permits heat exchange even in a small temperature difference is used in each condenser for a crude argon column, a deoxidation column, and a high-purity argon column in an argon separator utilizing air liquefaction and rectification. An oxygen-enriched liquefied air withdrawn from the plate located above the bottom of a lower column in a multi-rectifying column is used as a coolant for each condenser. Thus it is possible to widen the temperature difference between the condensation side and the evaporation side in the condensers for respective columns, to dispense with a blower for pressurizing crude argon even when the total number of theoretical plates of the crude argon column and the deoxidation column exceeds 100 and, consequently, to reduce apparatus and operation costs. Further, it is possible to render the condenser in each column small and compact, thus shortening the time taken for starting. Furthermore, the adoption of the liquefied air withdrawn from plates located above the bottom can eliminate a fear of hydrocarbon precipitation.

摘要： In a condenser/evaporator of the type in which first fluid chambers and second fluid chambers are formed alternately by a large number of vertical partition plates and heat-exchanging is effected between a liquid medium in the first fluid chambers and a fluid in the second fluid chambers, multiple stages of heat transfer plates are disposed vertically in the first fluid chambers so as to define a plurality of liquid medium flow paths. One of the ends of each fluid path is open. A plurality of liquid reservoirs whose upper parts are open are disposed vertically and are connected to the other ends of the flow paths. While being supplied to the liquid reservoir of each stage, the liquid medium is introduced into the flow paths to effect heat-exchanging. Accordingly, the liquid depth of the liquid medium becomes small and temperature rise due to the liquide pressure is eliminated so that efficiency of the condenser/evaporator can be improved.
