| 摘要 |
Embodiments of the invention provide an apparatus for the manufacture of polyethylene and polyethylene copolymers, The apparatus includes a primary compressor 1st fluid communication with a two-stage secondary compressor, the secondary compressor its fluid communication with a heated conduit in fluid communication with a tubular reactor, the tubular reactor including one or more reaction zones having a heating/cooling jacket, said reactor tube including an inner material and an outer material, said outer material being substantially inert in the presence of water under operating conditions, the tubular reactor in fluid communication with a product separator, and at least one conduit for the transfer of recycled ethylene from the product separator to the secondary compressor. Processes for manufacturing polyethylene and polyethylene copolymers using such an apparatus are also described. |
