Gas-phase polymerization reactor control |
| 摘要 |
A control method for controlling a fluidized bed polymerization reactor in the production of a given polymer product, the method comprising the following steps:
(a) determining a ratio of the production rate of the polymer product in the reactor to the pressure in the reactor,(b) setting a production rate of the polymer product in the reactor which production rate, on the basis of said ratio of step (a), corresponds to a desired pressure in the reactor;(c) adjusting the feed rates of monomers into the reactor in accordance with said set point production rate. |

1. A control method for controlling a fluidized bed polymerisation reactor in the production of a polymer, the method comprising the following steps:
(a) determining a ratio, (Y/Pm), of the production rate of the polymer in the reactor, (Y), to the pressure in the reactor, (Pm); (b) setting a production rate of the polymer in the reactor which production rate, on the basis of said ratio of step (a), corresponds to a desired pressure in the reactor; and (c) adjusting the feed rates of monomers into the reactor in accordance with said set point production rate. |
