WebbSlurry loop reactors have gained considerable application since 1960s, and large quantities of ethylene copolymers are produced annually via this process. (1−4) In a typical slurry-phase loop reactor for the production of polyethylene (PE), the reaction mixture consisting of monomers, diluent, catalyst, hydrogen, and polymers is circulated, driven by an axial … WebbSlurry operation may be either batch wise or continuous with respect to the flow of liquid and solid. In the latter case, the liquid (or slurry phase) may flow counter currently and co-currently to the gas. These reactors are sketched in Figure.1. In the present paper the studies on heat transfer coefficients in slurry bubble signed integers worksheet
