Apparatus for production of high pressure polyethylene
Abstract
Abstract AN IMPROVED METHOD AND APPARATUS IS PROVIDED FOR PRODUCTION OF HIGH PRESSURE POLYETHYLENE IN A SPARGER TUBE REACTOR. COLD ETHYLENE GAS IS RADIALLY INJECTED INTO THE POLYMERIZATION ZONE IS VARIABLE AMOUNTS AT SPACED INCREMENTS. CATALYST-RICH GAS IS ALSO INJECTED INTO THE POLYMERIZATION ZONE AT SPACED INCREMENTS IN VARIABLE AMOUNTS WITH RESPECT TO THE COLD ETHYLENE GAS INJECTION. INJECTION OF BOTH COLD ETHYLENE GAS AND CATALYST-RICH GAS, AT SPACED INCREMENTS AND IN VARIOUS AMOUNTS WITH RESPECT TO EACH OTHER PROVIDES CONTROL OF REACTION AND, THEREFORE, OF TEMPERATURE PROFILE. THUS, AN ESSENTIALLY CONSTANT TEMPERATURE AND PRESSURE PROFILE CAN BE MAINTAINED THROUGHOUT THE POLYMERIZATION ZONE.
