Definitions

  • FRANZ POLLIT ZER OF GEOSSHESSELOHE, NEAR IU'NICH, GERMANY.
  • the first mentioned manner of operating requires large surfaces for transferring the heat and consequently voluminous and expensive exchangers.
  • the tubes will be obstructed by ice which cannot be removed without an interruption of the operation.
  • the process above mentioned in thesecond place may be carried out with an apparatus relatively simple and less expensive, but in this case a device for interchanging the flow of gases and a rather complicated control are required.
  • the invention consists in a process for transferring heat from gases to other gases by which the above mentioned disadvantages are avoided.
  • the transmission is effected by the aid of a liquid.
  • Fig. 1 shows diagrammatically an arrangement for carrying out the invention wherein the heat exchange is from a compressed gas to an expanded gas
  • Fig. 2 shows diagrammatically a modification of this arrangement.
  • Figure .1 illustrates the case of the exchange of heatfrom a compressed gas to an ing the column expanded gas, for instance for the purpose of liquefaction, and assuming as the object I of the liquefaction. a refrigeration output at the'temperature ofthe methane under at-l mospheric pressure.
  • a refrigeration output at the'temperature ofthe methane under at-l mospheric pressure.
  • the compressed ethylene enters the first colunm 'A at the temperature of cooling water, leaves the column at its higher end band is ex anded to the pressure of one atmosphere by t e regulatlng valve V.
  • the gas thus cooled by expansion enters the second column B at c in which it will ascend and cool the descending liquid.
  • the auxiliary liquid must consist of a inaterial which meets the following requirements. On the one hand it is necessary that temperature and onvand conveyed through the valve columns in the same manner it will not become too viscous atthe lowest the other hand it must have such a vapour-tension at the highest temperature that the escape of material will not cause a considerable loss.
  • the evaporated quantities are to be, continuously replaced by addition of further liquid from a container E. It may also be advisable to recover the vapour passing off; together with the gas, for instance by absorption or dissolution.
  • thehea't. capacity In order to obtain a complete heat-exchange of liquid and gas, thehea't. capacity must be regulated in such a manner that it will be approximately equal at all temperatures. 11 the specific heat of the liquid decreases at lower temperatures in a quicker manner than that of the gas, as it may be often the case, this diminution may be equalized by increasing the quantity of circulat' ing liquid inthe cooler parts of the column.
  • This mode of operating is illustrated by Fi 2.
  • the liquid is partially. passed off at g D to the column B at 11,.
  • the remaining liquid passes through the whole lengthof the two as shown in Figure 1. In cases where more than two gases are to be treated, it, is: necessary to provide for a corresponding. number ofcolumns, so that a special column is available for each gas.
  • a process for transferring heat from gases to other gases which comprises causing a; compressed gas to ascend through a descending shower of a cool liquid in a cooling chamber. expanding said gases thereby further cooling the same and causing said gases to ascend through a descendin shower of a warm liquid in a second chamber.

  • a process for transferring heat from gases to other gases which comprises causing a compressed gas to ascend through a. descending shower of a cool liquid in a cooling chamber, expanding said gases thereby further cooling the same, causing 'said gases to ascend through a plurality of vertically spaced descending showers of a warm liquid in a second chamber, said liquid thus cooled by heat exchange with the expanded gases being forced into the first mentioned cham- .ber, descending "therein in heat exchange with said compressed gas before expansion and successfully withdrawing said llqu'id at vertical intervals from said first chamber and returning the same to corresponding showers in' said second chamber.
