of about 280 psia to at least about 325 psia in compressor 40 after compression in compressor 40 the feed stream is further cooled against cooling water and chilled refrigerant in heat exchangers 50 and 60 consecutively to a temperature of about 35 u00b0 f to about 45 u00b0 f the feed stream is again freed of condensed moisture in separator vessel 70 the dried stream is further dried by an adsorbent system 80 by way of example adsorbent system 80 may be an adsorbent bed of alumina although not shown carbon adsorption beds also can be used to extract any higher boiling hydrocarbons the clean and dried feed stream is then further cooled to near its dewpoint within column reboiler 90 this temperature is from about 0 u00b0 f to about 10 u00b0 f depending on the composition of the stream the feed stream is then substantially condensed against low pressure refrigerant in primary condenser 100 the feed stream is then flashed through valve 110 into a point near the top of distillation column 120 where it serves as a primary feed carbon dioxide is stripped from the liquid within column 120 column 120 operates at a temperature of about 25 u00b0 f to about 5 u00b0 f and a pressure of about 270 psia to about 320 psia liquid carbon dioxide which is essentially pure is collected from the base of column 120 in line 121 and a portion of this stream in line 122 is partially vaporized in column.
