CFD simulation of fluidized bed reactors for polyolefin production – A review
M.J.H. Khan,M.A. Hussain,Z. Mansourpour,N. Mostoufi,N.M. Ghasem,E.C. Abdullah 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.6
This literature survey focuses on the application of computational fluid dynamics (CFD) in variousaspects of the fluidized bed reactor. Although fluidized bed reactors are used in various industrialapplications, this first-of-its-kind review highlights the use of CFD on polyolefin production. It is shownthat CFD has been utilized for the following mechanisms of polymerization: governing of bubbleformation, electrostatic charge effect, gas–solid flow behavior, particle distribution, solid–gas circulationpattern, bed expansion consequence, mixing and segregation, agglomeration and shear forces. Heat andmass transfer in the reactor modeling using CFD principles has also been taken under consideration. Anumber of softwares are available to interpret the data of the CFD simulation but only few softwarespossess the analytical capability to interpret the complex flowbehavior of fluidization. In this review, thepopular softwares with their framework and application have been discussed. The advantages andfeasibility of applying CFD to olefin polymerization in fluidized beds were deliberated and the prospectof future CFD applications was also discussed.
