Abstract The solvent selection is very important in the ethylene slurry polymerization process. The influence of solvent on the different aspects such as the polyethylene solubility in different solvent, relationship between boiling point and operating pressure, the effect of solvent evaporation enthalpy on the way of reaction heat removal, and separation process of polymerization slurry, were discussed. The results show that n-pentane is the most feasible solvent to vertical stirrer polymerization reactor, and iso-butane and propane are better solvents to loop polymerization reactor.
