Know Your Options for Particle Fine Removal

Photo by David Geib on Pexels.com Process engineers struggle to clarify process liquids. Particle fine removal is part of the ongoing battle. But there are ways to automate the clarification processes to improve filtration and minimize operator exposure. The cake solid’s structure and the nature of the process will determine which types of pressure-filtration automated clarification technologies are best for you. Before we discuss removal of particle fines, let’s discuss how they are generated.…


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…

Benefits of a Continuum Approach to Optimizing Final Drying 

  As we announced in March, BHS has acquired AVA-GmbH. The AVA technologies provide for turbulent mixing, reacting and drying of wet cakes as well as powders and process slurries. The vertical and horizontal technologies are vacuum or atmospheric, batch and continuous, for final drying to “bone-dry” powders. They are an essential part of our “Continuum Approach.”  What do I mean by that? This blog briefly reviews our first ground-breaking study showing the benefits of a “Continuum Approach” to…


Changing from Batch to Continuous Processing

Our approaches to process engineering must always be evolving. Otherwise, we’ll never grow and innovate. Recently, I contributed a feature to The Chemical Engineer on making the change from batch to continuous processing. Here's an edited version of that article for my loyal blog readers.  As there is a push to become more efficient, many process industries have begun thinking about continuous processing. Many specialty and fine chemical operations are batch operated. It is easy and typically…


Contribute to a Holistic Approach to Unit Operations!

Photo by Andrea Piacquadio on Pexels.com As the chemical industry changes and becomes more integrated worldwide, there is a need for information exchange. This must include not only principles of operation but practical knowledge transfer. That’s why I have agreed to edit a new book for Elsevier, “Integration and Optimization of Unit Operations.” As my readers know, in 2015, I published the “Handbook of Solid-Liquid Filtration” with Elsevier, UK. This new project offers up-to-date and practical…
