Recovery of condensable products from gaseous mixtures

Patent ·
OSTI ID:5853321
A process is described for recovering liquid products from a gaseous mixture. The mixture is cooled initially by countercurrent heat exchange with separated constituents of preceding portions of the same mixture and a recycled refrigerant. This initial cooling condenses some of the constituents. The liquid product thus formed is separated from the gas. The gas is then expanded to a lower pressure while doing mechanical work to cool it to a still lower temperature and condense more liquid products, which are combined with the first liquid products obtained to provide a cold liquid product stream and a cold gas stream. The cold-product stream and a cold-liquid refrigerant stream are combined and passed in heat-exchange relationship with the gaseous feed stream to provide the initial cooling described above by partially vaporizing the combined liquid product and refrigerant stream.
