Abstract
The energy efficiency of a high pressure, high temperature continuous process for the production of polyethylene is improved and residual gases are more completely removed from the product without detriment to product quality by employing an intermediate separator between the first and second separators. The intermediate separator is maintained at a pressure between about 10 and 70 bars, and the second separator is maintained at a pressure between about 1 and 1.5 bars.
