Ebook Explores Automated Filtration Technologies for Clarification Applications

Over my almost 40 years in the process industry, many people have helped me along the way. Having opened my own consulting business, Perlmutter & Idea Development, I thought it time to give back to the engineering and process communities. Earlier this year I taught a short course in the American Filtration Separations Society Learning Center, “Automatic Filtration Technologies.” This month, I have released a related e-book, Framework for Selecting Automated Solid-Liquid Filtration…


Optimizing downstream final drying

Every year I look forward to attending AICHE, learning from peers, and sharing what knowledge I’ve gained in the past year. COVID-19 pushed us to meet virtually this year. Still, I was pleased to continue to share my talk on BHS-Sonthofen Inc.’s continuum approach to optimizing downstream final drying with upstream solid-liquid filtration. I thought I’d offer a recap here for those who missed the online event. Most often when analyzing a new process development approach, engineers take a…


Slurries

Containment of Slurries in Continuous and Batch Operations

Image source In the 1970s, the chemical operations used acetone and benzene for the main slurries solid-liquid separation process. Next, there was a push to minimize solvent use. We looked to use water as the process liquid, but still had open filter presses and rotary drum filters; the entire plant was white from titanium dioxide or pharma stearates. Today, we all know that processes remain open with filter presses, vacuum filters, and centrifuges. Our job is finding solid-liquid separation…


Clear thinking about automated clarification technologies

Photo by SplitShire on Pexels.com This is an edited version of an article I wrote for The Chemical Engineer. I hope you enjoy this take on automated clarification technologies. Throughout my career in the solid-liquid separation market space, I have seen some interesting solid-liquid separation solutions. At one melamine resin facility, the slurry was in a formaldehyde process. The operators were wearing masks, opening up a manual plate filter in a room with residential floor fans, to dig out…

Real World Examples of Particle and Cake Formation Influences

Image source Process engineers might love it if all of the filtration technology solutions they developed ran flawlessly, at all times, under all conditions. But, this isn’t realistic. Something might go wrong with the filtration mechanism itself. A change in the environment — upstream or downstream — could cause problems with particle or cake formation. Even the smallest shift in the operation process or procedure can prompt the dreaded phone call to the engineer: “the filtration system isn’t…
