Process Engineering Choices

Have you ever heard of “analysis paralysis?” It’s a state process engineers might know well. Being confronted with so many different approaches and varied equipment available, we can be left stuck wondering what to do next.

 

The recent BHS newsletter looked at just this indecision from the perspective of a process engineer facing the challenges of acidic slurries and vacuum filtration.  We began by sharing the perspective of Garrett Bergquist, the BHS Process & Application Engineer, who is presenting at the AICHE annual meeting in San Francisco this month.

 

Garrett’s article discusses belt filter technologies, materials of construction and proper vacuum belt selection.  His focus in particular is on alternate materials available in vacuum belt filter construction. He furthered his insights with a case study addressing chemical compatibility to process 2,200 kg/h dry solids precipitated from a sulfuric acid solution.

Noting stainless and carbon steels are often incompatible with most sulfuric and hydrochloric acid concentrations, he concluded, “when it comes to dealing with hazardous slurries such as those containing sulfuric or hydrochloric acid the options should be carefully considered.”

 

 

Also in the latest A&SoF newsletter, we announce our Vacuum Belt Filter skid. This mobile skid (see the wheels?) is 0.3m2, including liquid ring vacuum pump, separator, transfer pump, instrumentation and PLC controls. Plus, its fully-wired for quick electrical hook-up.

 

Finally, we offered a presentation of BHS’s laboratory filtration testing capabilities. Filtration Laboratory Manager Ron Baltz’s overview of the new Charlotte facility covers all of the bases. But, if you still have questions, let me know.
