The purification of benzoic acid using dividing wall columns
In one recent project for a customer based in Asia, the authors’ company suggested the combination of distillation and crystallization techniques to obtain high-quality purified benzoic acid. Encouraged by the successful startup of this processing train, the customer began to schedule a second project. The authors’ company was asked to optimize the purification process to improve cost and operational efficiencies. The two existing columns, which remove lights and heavies, respectively, from the crude benzoic acid feedstock were investigated to identify key opportunities. The feasibility study based on the feed composition confirmed that the existing columns could be converted into a single dividing wall column (DWC).
Utilize a hydrogen reactions lab to optimize renewable fuels processing
Leading technology developers in the refining space are utilizing various catalysts to enhance the adjusted reaction chemistry, but this does not directly address how to optimize hydrogen utilization for the hydrodeoxygenation and isomerization/cracking processing steps. To ensure the right equipment outlay and calibration for these hydrogenation applications, replicating the process in a lab setting can help identify efficiencies and yield improvements for a fraction of the cost that a refiner would incur attempting to achieve that optimization through modifications at commercial scale.

Catalyst safety assessment: Making catalyst and adsorbent startups safer
An unease around potential high temperature and pressures during fresh catalyst and adsorbent startups—which can lead to situations where designed pressures and temperatures are exceeded—led the authors’ company to create the Catalyst Safety Assessment (CSA) methodology.
