Abstract
Improved heat exchanger systems and processes for cooling recycled off-gas in high pressure low-density polyethylene production. A system for exchanging heat between a first material and a second material can include a shell for containing the first material therein, a plurality of tubes disposed within the shell for containing the second material therein, a tube sheet disposed at an end of the shell for restricting flow of the second material to the shell, and at least one collector conduit disposed exterior to the shell for receiving at least one end of the plurality of tubes, wherein at least one of the plurality of tubes extend through the tube sheet to the collector conduit. A cleaning tool can be disposed within the collector conduit for cleaning the tubes. A process for cooling a gas stream can include introducing the gas stream to the heat exchanger system provided herein.
