    !. ühlverfahren   zur fraktionierten Gewinnung von Paraffin unter gleichzeitiger Rückkühlung des ausgenützten Kühlmittels. 



   Bei der   Parafnndarstellung scheiden sich   während der Kühlung der Paraffinöle bekanntlich schon bei 00 Paraffine aus, die einen höheren   Schmelzpunkt   haben. Bei tieferen Temperaturen treten Ausscheidungen von weicheren Paraffinen mit niederen Schmelzpunkt ein. Wenn nun 
 EMI1.1 
 in Anwendung gebracht wird, so ist die Folge davon,   da'3 zieh   an den Wänden der   Kühlgefässe   Paraffine ausselheiden, die im weiteren Verlauf des Prozesses schädlich sind und deren Absonderung erst in umständlicher Weise durch nochmaliges Erwärmen und Schmelzen erfolgen muss. 



   Um nun diesen Nachteil bei der   Paraffingewinnung   zu beseitigen und einerseits eine Regelung der Temperatur des Kühlmittels vor oder bei dem Eintritt in   jedes einzelne Kiihlgefäss   zu   ermöglichen,   so zwar, dass mit einer einzigen   Kühlanlage unter gleichzeitiger Kraftersparnis   
 EMI1.2 
 wird nach dem den Gegenstand der Erfindung bildenden Verfahren in folgender Weise vorgegangen :
In einer Kühlanlage mit zwei Refrigeratoren werden   zwei verschieden kalte Kühlmittel   erzeugt.

   Das eine wird in dem einen Refrigerator soweit abgekühlt, dass es eine Temperatur von

   erwärmte Kühlmittelgemisch   entweder durch kaltes Wasser,   kalte Luft u.   s.   w.   bis auf die für   die zweite Rohrleitung erforderliche Temperatur   (z.

   B. +   5") abgekühlt oder durch   den, Kiihlmittel von dieser höheren Temperatur (+ 5 ) liefernden Refrigerator geleitet und ein Teil desselben mit dieser Kühltemperatur sofort wieder in das eine Leitungsrohr der Kühlanlage weitergeleitet

    ! Cooling process for the fractional recovery of paraffin with simultaneous re-cooling of the used coolant.



   In the case of paraffin representation, it is known that paraffins, which have a higher melting point, are already precipitated at 00 when the paraffin oils are being cooled. At lower temperatures, excretions of softer paraffins with a lower melting point occur. If now
 EMI1.1
 is brought into use, the consequence of this is that paraffins separate on the walls of the cooling vessels, which are harmful in the further course of the process and which must first be separated out in a laborious manner by repeated heating and melting.



   In order to eliminate this disadvantage in the production of paraffin and, on the one hand, to enable the temperature of the coolant to be regulated before or at the entry into each individual cooling vessel, indeed that with a single cooling system with simultaneous power savings
 EMI1.2
 is proceeded according to the method forming the subject of the invention in the following way:
In a cooling system with two refrigerators, two different cold coolants are generated.

   One is cooled down in one refrigerator until it has a temperature of
 EMI1.3
 
 EMI1.4
 Mistake. which open at a common point in the cooling jacket of the vessel, so that the two coolants can be mixed in a ratio corresponding to the respective required temperatures.
 EMI1.5
   heated coolant mixture either by cold water, cold air and the like s. w. except for the temperature required for the second pipeline (e.g.

   B. + 5 ") cooled or passed through the, coolant of this higher temperature (+ 5) delivering refrigerator and a part of the same with this cooling temperature immediately passed back into a conduit of the cooling system
 EMI1.6
 which causes the cooling to -10. As a result, the cooling capacity in the refrigerator supplying the warmer liquid is increased accordingly and the overall capacity of the cooling system is thus actually increased.
