PHOSPHINE THERMAL OXIDIZER WITH PHOSPHORIC ACID SCRUBBER SYSTEM
Nov 25, 1998
Matrix Engineering provided the concept drawings, budget estimates, structural, mechanical, and electrical engineering necessary to replace an existing thermal oxidizer, hydrator and mist eliminator. The new thermal oxidizer and quencher required a 5-story roofed structural tower. The new mist eliminator required its own support and access structure. We also provided all the engineering necessary to install a new 300-hp exhaust fan. Controls for the scrubber system were integrated into an existing DCS system. Besides all structural drawings, we also provided all process, general arrangements, foundation ductwork, piping and electrical drawings.
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!
