ONLINE FILTER MONITORING AVOIDS DOWNTIME

摘要

Emerson Process Management Smart Wireless technology is enabling INEOS to monitor filters within poly-ethylene pellet transportation tubes (www2.emersonprocess.com). The polyethylene pellets are passed through the transportation tubes using compressed air. The incoming air is filtered to prevent any pollution of final product. The filters become blocked over time and lose their efficiency, which in turn affects the quality of the end product. A liquid column (U-tube) was installed across the filter, indicating the differential pressure. An increase in the pressure suggests that the filters are blocking.
