Abstract

THIS INVENTION IS DIRECTED TO A METHOD OF REMOVING ACETALDEHYDE, CO2 AND/OR WATER FROM AN ETHYLENE AND/OR PROPOYLENE CONTAINING STREAM. IN THIS INVENTION, ACETALDEHYDE AND C4+OLEFINS ARE SUBSTANTIALLY REMOVED FROM THE ETHYLENE AND/OR PROPYLENE CONTAINING STREAM. THE STREAM IS THEN ACID GAS TREATED. THE ETHYLENE AND/OR PROPYLENE STREAMS WHICH ARE SEPARATED AND RECOVERED ACCORDING TO THIS INVENTION CAN BE FURTHER PROCESSED, FOR EXAMPLE, TO MAKE POLYMERS SUCH AS POLYETHYLENE AND POLYPROPYLENE. (FIG. 1)
