The polyethylene unit of Fushun Ethylene Chemical Plant adopts the solution process to produce linear all-density polyethylene based on the theory of anionic coordinating polymerization. Using polymer-grade ethylene as monomer,1-butene or octane as comonomer, H2as molecular weight regulator, polyethylene particle product is produced in cyclohexane solution by using improved Ziegler catalyst. The reaction control process has great effect on the unit’s energy consumption and product quality, so the reaction optimization control plays an important role in daily production.
