Abstract:
1. A process for feeding ethylene into a polymerization system operating in a liquid phase or supercritical phase comprising: providing a low-pressure ethylene stream, one or more low-pressure C metering the low-pressure ethylene stream, the one or more low-pressure C blending upstream of the one or more reactors the metered low-pressure ethylene stream, the metered one or more low-pressure C pressurizing the ethylene-carrying low-pressure blended liquid feed stream to the polymerization system pressure with one or more high-pressure pumps to form an ethylene-carrying high-pressure blended reactor feed stream; and feeding the ethylene-carrying high-pressure blended reactor feed stream to the one or more reactors configured in parallel, in series, or a combination thereof.
