- the feed mixture Before entering the cold box, the feed mixture is first cooled to about -25 0 C. The resulting condensate is led directly into the deethanizer. The non-condensed vapors are further cooled within the cold box to about -90 0 C, wherein the resulting product-rich condensate is also passed to the deethanizer after heat exchange.
- the coldbox thus represents a single-stage coarse separation.
- the remaining vapor phase which contains substantially non-condensable components, for example hydrogen, is, after heat exchange in the stream entering the coldbox, relaxed. Due to the Joule-Thompson effect, the low boilers cool to about -110 0 C from. This temperature level is used to partially condense the stream entering the coldbox.
