PROCESS FLOW DIAGRAM POLYETHYLENE
Major safety concerns are around the plug flow reactor: Free radical polymerization of ethylene to polyethylene is a highly exothermic reaction Converts gaseous ethylene into viscous polyethylene melt Thus many constraints must be taken for a process that aims to be effective and safe: reactor temperature (prevent unideal and
