Abstract

Abstract: Fluidized reactors are widely used in the production of polyethylene and polypropylene. The design of gas distributor is one of the key issues in the scale-up of fluidized bed reactors. Taking the conical cap porous distributor as an example, this paper introduced the design method of such key parameters as the opening rate, pressure drop, hole spacing and so forth.It presented the design steps of conical cap porous distributor and applied these steps to the design of gas distributor in fluidized bed reactor in actual industrial production.

Key words: fluidized bed, olefin polymerization, gas distributor, design
