ABSTRACT:
In a method for the refrigerative fractionation of cracking gases in ethylene production plants, the improvement consisting in that ethane is used as the refrigeration fluid, it being thus possible to attain very low temperatures, down to minus 88.degree. C.: concurrently, the condensation with water is practicable whenever water is available in large masses at a temperature which is in the range from zero centigrade to +25.degree. C.; that is the case of sea waters in cold countries or fresh waters in cold climate. A considerable first-cost and running economy become thus available.
