Abstract:
1. A method of controlling a slurry catalyst flow comprising the steps of: (a) providing a slurry catalyst composition; (b) splitting the slurry catalyst composition into a primary slurry catalyst composition and a secondary slurry catalyst composition; (c) measuring a primary slurry catalyst composition flow rate of the primary slurry catalyst composition; (d) supplying the primary slurry catalyst composition to a primary catalyst injection device; (e) measuring a secondary slurry catalyst composition flow rate of the secondary slurry catalyst composition; (f) controlling a process parameter of a secondary slurry feed system based on a ratio of the primary slurry catalyst composition flow rate to the secondary slurry catalyst composition flow rate, wherein the process parameter affects the secondary slurry catalyst composition flow rate; and (g) supplying the secondary slurry catalyst composition to a secondary catalyst injection device.
