Changing from Batch to Continuous Processing
Photo by Lalit Kumar on Unsplash 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…
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…
