LUKE, MARYLAND PAPER MILL PETROLUEM COKE DENSI-FEED™ SYSTEM

Matrix provides a PLC based TUGMONITOR for a 6000HP TWIN ENGINE NEW BUILD. Communicates seamlessly via ethernet with GE Engines.

Matrix provided conceptual and hard mechanical design of a heavy duty screw feeder for metering phosphorus pentoxide (crystallized phosphoric acid) into a dissolve tank. Due to the hot reaction during hydration in the tank (resulting into very hot phosphoric acid) the variable speed screw feeder consisted of a 316L S/S 12 inch diameter auger and 1/2 inch thick trough. A special dump hopper with automated closing lid was designed with a large grated opening and bypass chute at the inlet of the feeder. Very special design considerations were made for protecting the conveyor seals and bearings from making contact with the hot acid. Our design allowed the acid crystals or hot liquid to fall out into an isolated gap and into the tank before it challenged the seal. This was a highly successful design has virtually eliminated the huge stock piles of drummed feedback material that accumulated due to the inability to dissolve the crystallized acid safely.
