Dual reactor process and apparatus for polymerizing ethylene |
| abstract |
Ethylene is polymerized in a dual reactor system in which two reactors are connected in series with a heat exchanger, or intercooler, disposed therebetween. The reaction stream from the first reactor at elevated pressure and temperature is passed through the heat exchanger to effect cooling of the stream. Following passage through the heat exchanger, the pressure of the cooled reaction stream is reduced through a pressure let-down valve and the stream is thereafter introduced into the second reactor wherein further polymerization takes place. The reactors can both be of the autoclave type although one of the reactors can be of the tubular variety. |
