| titleOfInvention | Heat transfer in a polymerization reactor |
| abstract | A process comprising: polymerizing an olefin monomer in a loop reactor in the presence of a catalyst and a diluent; and producing a suspension comprising a solid particle olefin polymer and a diluent, wherein the internal Biot number is maintained at or below 3.0 within the loop reactor during polymerization, wherein the suspension in the reactor loop forms a suspension film that has a coefficient of suspension film along an inner surface of a wall of a reactor, and where the film coefficient of the suspension is less than 2,800 Wm-2-K-1 (500 BTU-h-1-foot-2- ° F-1), where the internal Biot number is defined using the following equation: ** Formula ** where Bint is the internal Biot number, hsuspension is the coefficient of slurry film defined above in units of Wm-2-K-1 (BTU-h-1-foot-2- ° F-1), LR is the characteristic length of the reactor wall (thickness 212) in units of m-1 (foot-1), and k R is the thermal conductivity of the reactor wall in units of Wm-1-k-1 (BTU-h- 1-foot-1- ° F-1), where the coefficient of the suspension film is approximated using the following equation: ** Formula ** where hsuspension is the coefficient of the suspension film in units of Wm- 2-K-1 (Btu / (h) (foot2) (° F) (for example, which can also be expressed as BTU-h-1-foot-2- ° F-1)), f is the friction factor of Fanning, Ks is the thermal conductivity of the reactor suspension in units of Wm-rK-1 (Btu / (h) (foot) (F)), D | is the internal diameter of the reactor wall in units of m-1 (foot), Prs is the Prandtl number of the suspension, and Res is the Reynolds number of the suspension. |
