MATRIX PROJECTS
PERDUE HILL, ALABAMA DUAL PETROLEUM COKE DENSI-FEED™ SYSTEM
Feb 02, 2007
Matrix provided the system engineering and critical equipment packages with silo for a dual discharge petcoke delivery system at GP Cellulose in Perdue Hill, Alabama. This system was designed to accept petcoke from pneumatic railcars or trucks and feed two lime kiln burners from a common 180 ton silo. A dual discharge hopper bottom was specifically designed for two petcoke DENSI-FEEDERS, though initially, GP chose to implement the project in two phases and only installed one of the two feed systems. Matrix commissioned the second kiln feed line 2 years later.
A stepped convey line and 100hp blower was used on the rail unloading system for a record unloading time of 2 hours for 100tons at a distance of 200ft away.
A pneumatic conveying system with a variable rate blower delivers petcoke to the burner in accordance with the specific air flow requirements for flame shaping. Control of the Matrix system was integrated into the mill's existing DCS. The system is able to co-fire fire petcoke, fuel oil, natural gas or tall oil.
The first kiln’s system at was proven and tested to 3.0 tph with natural gas and successfully burned in excess of 2.4 tph of petcoke in combination with fuel oil. Below is a picture of the flame at 2.5 tph with fuel oil.

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.
Matrix Industrial Systems was proud to work in conjunction with AC Marine in designing and supplying critical systems for Georgia Aquarium's newest venue to experience sharks directly with the grand opening of their 1.2MM gallon Shark Tank. This attraction allows you to submerge into the tank within a shark cage and begin an underwater journey traversing the pool as it is suspended and moved by a hoist/monorail system. Breathing air for the participants is supplied through an umbilical tethered to the cage and connected to a specialized Breathing Air Control System (BACS). Matrix supplied and installed this system with its umbilical as a turnkey project. Matrix and AC Marine were proud to be guinea pigs (or should I say SHARK BAIT) on the maiden voyage!
