PROCESS SCRUBBERS AND DUST COLLECTION SYSTEMS
RHODIA - PHOSPHINE INCINERATOR SCRUBBER SYSTEM
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.
RHONE-POULENC - CATALYST SCRUBBER
Matrix Engineering provided the structural and mechanical engineering necessary to replace a mist eliminator within the catalyst scrubber system at the Nashville, Tennessee plant. The new kynar lined mist eliminator was designed with expansion of the scrubber system in mind. However, spatial constraints dictated we have a very close coordination with the vessel designer and fabricator for an almost impossible fit. The existing structural steel was also upgraded to accommodate the new heavier vessel. Besides structural design and detail drawings, we also provided vessel arrangement, fiberglass ductwork layout and details, and piping drawings.
RHODIA –ANHYDRIDE ACID SCRUBBER
Matrix Engineering provided the concept drawings, budget estimates, structural, mechanical, and electrical engineering necessary to install a venturi/flooded elbow scrubber system with a mist eliminator at the Nashville, TN plant. A new multi-level structure was used to support and access the new scrubber and mist eliminator. This structure adjoined an existing structure and tank that were utilized for the project. The project also included a drum dumping and a lump feeding system as well as a tote-bin wash-down station. These handling projects were very difficult due to the extreme corrosive nature of the product. Besides structural design and detail drawings, we also provided vessel arrangement, ductwork layout, piping design and details, as well as electrical.
RHONE-POULENC - METAL DETECTION
Our group provided the structural, mechanical, and electrical engineering necessary to replace an existing mechanical mixer, bucket elevator and transfer screw conveyor distribution system with a pneumatic convey/blending system. The intent of the project was to eliminate mechanical metal producers from contaminating the food grade product. Metal detectors were also installed just ahead of the packaging system. A central dust collection system was also required for blending and packaging. This was a very engineering intensive project due to spatial constraints and limited available shutdown time for installation.
U.S. TOBACCO-EXHAUST STACK SUPPORT
We provided the design for a new scrubber discharge exhaust stack complete with guy system. Also required were structural support modifications to accept the new stack as well as the new scrubbers.
