Abstract

1. Способ охлаждения одно- или многокомпонентного потока, в частности, обогащенной углеводородами фракции, косвенным теплообменом со смесью охлаждающего средства в циркуляционном контуре смеси охлаждающего средства, причем смесь охлаждающего средства сжимают по меньшей мере в две ступени и разделяют на низкокипящую сжатую до конечного давления циркуляционного контура смеси охлаждающего средства фракцию смеси охлаждающего средства и по меньшей мере одну высококипящую сжатую до промежуточного давления фракцию смеси охлаждающего средства, отличающийся тем, что высококипящую фракцию (5) смеси охлаждающего средства нагнетают (Р11) до давления низкокипящей фракции (8) смеси охлаждающего средства и перед косвенным теплообменом (Е1) или непосредственно в его начале объединяют с низкокипящей фракцией (8) смеси охлаждающего средства.2. Способ по п.1, отличающийся тем, что нагнетание (Р11) высококипящей фракции (5) смеси охлаждающего средства проводят в одну или несколько ступеней.3. Способ по п.1 или 2, отличающийся тем, что объединение или соответственно смешение высококипящей (5') и низкокипящей фракций (8) смеси охлаждающего средства проводят в специально для этого сформированной области теплообменника (Е1).
