Title:
APPARATUS AND METHOD FOR MEASURING THE STATIC CHARGE OF FLOWABLE SOLIDS
Document Type and Number:
WIPO Patent Application WO2002041011
Kind Code:
A8
Abstract:
This invention relates to an apparatus and method for measuring the static charge developed by a flowable solid as it passes through a conduit. A flowable solid (for example, a metallocene catalyst) is conveyed through a 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.
