MATRIX PROJECTS
HODGE, LOUISIANA DUAL PETROLEUM COKE DENSI-FEED™ SYSTEM
Oct 02, 2005
Matrix provided the complete engineering package for a dual discharge petcoke delivery system for Smurfit Stone Containerboard Division in Hodge, Louisiana. The system was designed to feed two lime kiln burners from a common 180 ton silo. A dual discharge hopper bottom was specifically designed for two petcoke DENSI-FEEDERS. It included dual pneumatic convey systems with variable rate blowers to deliver petcoke to the Coen burners in accordance with the manufacturer's specific air flow requirements. The convey distance of the petcoke was in excess of 600 feet. The system allowed the mill to report substituting up to 90% ground petcoke for natural gas in each of their lime kiln burners. The control of the Matrix feed equipment was integrated into Smurfit Stone’s existing DCS. Matrix provided all the civil/structural, mechanical, and electrical engineering for the project.
The project was commissioned shortly after Hurricane Katrina during very high natural gas prices. As a result, the mill was able to pay for its investment on 2 Kiln Fuel Systems WITHIN 4 MONTHS!

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!
