Following heavy fuel combustion in the refinery of Exxon Mobil, three electric filters separate the arising ash.
Underneath each electric filter, six pressure conveying vessels are mounted, transporting the ash via a common conveying line into a silo. Thus, conveyance of the complete ash by means of three conveying lines is ensured. STAG Triplex nozzles serve as silo discharge system. A truck loading facility fed the ash into trucks.
The configuration of the plant conforms to Exxon Mobil regulations, and the system is controlled by means of a STAG control.
