Abstract
A process for cooling and condensing natural gas in a plurality of convective heat exchange stages by means of multicomponent refrigerants. The first refrigerant cools the natural gas and the second refrigerant from ambient temperature in a first heat exchange stage. Then the second refrigerant cools the natural gas further in a second stage and afterward is compressed while still below ambient temperature to an intermediate pressure where it is joined by the first refrigerant for further compression and cooling to ambient temperature before separating the two refrigerants and repeating the refrigeration cycle.
