IONEX Research Corporation produces high performance equipment used to protect the environment and personnel from hazardous airborne chemicals and contaminants (click here to visit the IONEX website). IONEX was requisitioned to deliver a Thermal Catalytic Oxidizer/ Selective Catalytic Reducer for filtering offgas emitted from a nuclear waste treatment facility.
The unit consisted of a heat exchanger, a heater, three banks of oxidizing catalysts and three banks of reducing catalysts. Positioned in the offgas stream between the oxidizing and reducing catalysts was an ammonia injection grid that supplied anhydrous ammonia to the offgas stream for reducing NOx. As part of the requisition, their customer required that IONEX demonstrate that the ammonia is distributed evenly into the offgas stream to ensure adequate NOx reduction. IONEX turned to Endesin to design the ammonia injection grid and spec the appropriate, commercially available nozzles.
The steps used to design the ammonia injection grid were as follows:
NX Advanced Simulation was used as the pre and post processor and the solver used was NX Flow.
IONEX is able to secure projects that require engineering capabilities that other firms can't provide because they can rely on Endesin to for the most advanced engineering tools available as well as the expertise needed to use them effectively. This project was yet another example of Endesin’s engineering capabilities being seamlessly integrated into an existing engineering team to take on a new level of engineering complexity.
