Novel Filtration Technologies for Pharmaceutical Hydrogenation

Image source When it comes to removing catalyst fines from pharmaceutical hydrogenation reactions, BHS Filtration has come up with a novel approach. Currently, most hydrogenation slurries are clarified with the use of manual plate or nutsche filters, bag filters, or cartridge filters. All of these require manual operations for cake discharge and cleaning between batches or campaigns. At the same time, these units suffer from high labor, maintenance and disposal costs as well as the exposure of…

Become a Filtration Tech Troubleshooting Expert

Image source Recently I addressed the too-familiar telephone call that the “filtration system is not working.” When the call comes in — and so seldom during regular business hours —  filtration tech experts have to react quickly to solve the problem. Now, the question is how do you avoid getting these types of calls in the first place?  Well, you can turn off your cell phone, but maybe isn’t the best idea.  Instead, the better approach is proactive troubleshooting.  Proactive Filtration Tech…

Filtration of Liquefied Gases & Caesar’s Last Breath

foter.com On the heels of my blog about “The Business of Breathing,” it’s time to talk about gas. I recently finished reading the Sam Kean book “Caesar’s Last Breath.”  For those of you who have not read Kean, his specialty is writing science books in an exciting and entertaining fashion.  His three other books focus on the elements in the periodic table, genetics, and the brain.  Meanwhile, Caesar’s Last Breath looks at gases and both how the atmosphere has shaped human beings and how human…

Best Practices for Filtration Testing for Solid-Liquid Separation

Photo by Pacific Northwest National Laboratory - PNNL on Foter.com / CC BY-NC-SA Testing in school has a negative connotation. Students dread tests. Parents bemoan “teaching to the test.” Teachers chafe against the curriculum parameters defined by testing expectations. Yet, the word “testing” should resonate much more positively with process engineers. After all, testing is the key for selecting the most suitable filtration tech for any individual solid-liquid separation task. Although there is…
