A METHOD OF RECOVERING CONDENSABLE VAPORS, INCLUDING THOSE WHICH FORM HYDRATES, CONTAINED IN MIXTURES COMPRISING, FLOWING THE MIXTURE FIRST INTO A FIRST SEPARATOR MAINTAINED AT A RELATIVELY HIGH PRESSURE AND TEMPERATURE SUFFICIENT TO LIQUEFY A PORTION OF THE CONDENSABLE VAPORS OF THE MIXTURE AND SUFFICIENT TO PREVENT THE FORMATION OF HYDRATES IN THE FIRST SEPARATOR, FLOWING THE UNCONDENSED VAPORS FROM THE FIRST SEPARATOR TO A HEAT EXCHANGER MAINTAINED AT SUBSTANTIALLY THE SAME PRESSURE AS THAT OF THE FIRST SEPARATOR BUT AT A RELATIVELY LOWER TEMPERATURE SUFFICIENT TO CONDENSE A PORTION OF THE CONDENSABLE VAPORS FROM THE UNCONDENSED VAPORS AND TO FORM HYDRATES IN THE HEAT EXCHANGER, REDUCING THE PRESSURE OF UNCONDENSED VAPORS FROM THE HEAT EXCHANGER SUFFICIENT TO LOWER THE TEMPERATURE THEREOF SO THAT ADDITIONAL UNCONDENSED VAPORS WILL BE CONDENSED AND HYDRATES WILL FORM AND FLOWING THEM TO A SECOND SEPARATOR MAINTAINED AT A SUBSTANTIALLY LOWER PRESSURE AND TEMPERATURE THAN THE FIRST SEPARATOR AND SUFFICIENTLY LOW TO CONDENSATE LIQUIDS AND FORM HYDRATES THEREIN FOR SEPARATION OF SAID ADDITIONAL CONDENSABLE VAPORS AND HYDRATES THEREFROM, FLOWING THE COOLED UNCONDENSABLE VAPORS FROM THE SECOND SEPARATOR TO THE HEAT EXCHANGER IN INDIRECT HEAT EXCHANGE RELATIONSHIP WITH THE UNCONDENSED VAPORS FROM THE FIRST SEPARATOR FOR CONDENSING A PORTION THEREOF AND FORMING HYDRATES THEREIN AS AFORESAID, DISCHARGING THE COOLED UNCONDENSED VAPORS FROM THE HEAT EXCHANGER, COLLECTING THE CONDENSED VAPORS FROM THE FIRST AND SECOND SEPARATORS AND THE HEAT EXCHANGER, AND REVERSING THE PROCESS BY FIRST FLOWING THE MIXTURE INTO THE SECOND SEPARATOR WHILE MAINTAINING THE SECOND SEPARATOR AT A RELATIVELY HIGH TEMPERATURE AND PRESSURE SUFFICIENT TO MELT HYDRATES FORMED THEREIN AND TO CONDENSATE AND TO LIQUEFY A PORTION OF THE CONDENSABLE VAPORS OF THE MIXTURE AND TO PREVENT THE FORMATION OF HYDRATES THERE-
