摘要： The present invention relates to a method and apparatus for controlling static charges in a fluidized bed olefin polymerization reactor. Static charges which develop in the polymer products are measured and, if they fall outside a predetermined range, static charge control agents are introduced into the reactor. By controlling the static charges in the reactor, sheeting and drooling can be controlled.

摘要： The invention relates to a method for evaluating the condition of a fluidized bed reactor by examining the condition of the reactor wall. Specifically, the invention relates to a method for measuring static in the reactor using a static probe that is located at the distributor plate and comprises a distributor plate cap. The invention also relates to methods of determining a static level using a radio frequency (rf). The static measurements are provided to indicate or predict major continuity disturbances in the fluidized bed gas phase reactor.

摘要： An apparatus for measuring and a method for controlling the static charge developed by a flowable solid as it passes through a conduit. The flowable solid is conveyed through the conduit in such a manner that the powder develops a static charge due to the triboelectric effect as it moves against the conduit walls. The static charge on the solid is then measured using a static charge measuring device such as a Faraday drum or cage.
