PROCESS STRUCTURES
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.
COMMONWEALTH ALUMINUM
Provided a design for a structural steel tower to support two 5’ wide x 20’ vibrating screens operating 18 feet above the plant floor. Each screen had three screening decks and had a unit weight of over 13 tons. Design included a dynamic analysis of the structure due to forces emitted from the vibrating screens. Fabricator was Lecorp of Paducah, KY. Project was installed during the Spring of 1998.
BLOUNT INDUSTRIAL/BROWN & ROOT
Structural engineering was provided to Blount Industrial of Grand Island, Nebraska to support a 300-foot long 30" belt conveyor in a tubular steel gallery as part of a Southwest Portland Cement project under Brown & Root. This 8’-6" diameter tube was 237 feet long. The supports included three bents and a 50-foot tower at the discharge end.
COSTAIN COAL - NEW PORTAL STEEL DESIGN
Provided the design and detailing for structural steel in the new East Portal access shaft. The 600+ tons of steel include guide brackets for the 26 ft diameter service elevator as well as framing at the two stations being accessed.
RHODIA - PLATE AND FRAME FILTER
Matrix Engineering provided the concept drawings, budget estimates, structural, mechanical, and electrical engineering necessary to install a plate and frame filter press housed in its own building and an adjacent covered tank farm at the Nashville, TN plant. The objective of the project was to replace the existing rotary drum filter and centrifuges with the more efficient filter, which decreased the amount of lost product and doubled the production capability. The existing concrete bunker, where filter cake was dumped, was utilized as the base for the new building for the filter. A new tank farm was installed to service the filter with wash-water, filter supply, and filtrate tanks. The highly automated filter was equipped with a PLC controller, which was integrated to the DCS control system of the plant. The rest of the equipment was integrated with the DCS system that controls the plant.
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.
