  • condenser-evaporator refers to a heat exchanger in which a first condensing fluid stream undergoes indirect heat exchange with a second evaporating fluid stream.
  • Each condenser evaporator has a

  • the outer dimensions of the coldbox usually determine the transport dimensions of the package in prefabricated systems.
  • the "height" of a coldbox is understood to mean the dimension in the vertical direction in relation to the orientation of the coldbox in plant operation; the "cross section” is the area perpendicular to it (horizontal). During transport, the height of the coldbox determines the transport length, the cross section the transport height and width.
  • PUs are manufactured in a factory that is regularly far away from the site of the air separation plant. This allows extensive prefabrication and thus a minimization of the manufacturing effort at the site, where often prevail much more difficult conditions.
  • the prefabricated package or several prefabricated packages are transported from the factory to the site, the coldbox package with one or more Trennklah in horizontal arrangement. There are restrictions on the length and width of the packages for such transports. So far, this technology has only been used in medium-sized air separation plants, if the columns are at least partially lined up with ordered packings equipped, because packed columns usually require a greater height than floor columns.

  • a "subcooling countercurrent" is a unit separate from the main heat exchanger and serves to subcool one or more liquids from one of the columns of the nitrogen column distillation column distillation system or even from a mixing column countercurrent to one or more cold gaseous recycle streams or warm up.
  • These reflux streams come from a column of the distillation column system (in the case of two-column or multi-column systems, generally from the low-pressure column).
