This issue will focus on "Process Scale-Up"

Welcome to A&SoF. A&SoF is an e-newsletter, managed by BHS, with its sole purpose to enhance the filtration knowledge of the marketplace to solve actual plant problems. This is year number 6 for the newsletter and we will continue to work diligently for a “true” newsletter containing technical articles and ideas from many authors (and bloggers) in the industry.

The new BHS blog is now up and running, (www.perlmutterunfiltered.com). The blog is described below and we are looking for guest bloggers to contribute. Contact me through the link on the blog and let me know your ideas. The goal is to have this blog become a communication tool for all us to exchange of information on process topics. Thanks for your help to make this successful.

This issue focuses on process scale-up both for specialty chemicals as well as for bioenergy. The two articles discuss how to scale up and how technology may change based upon which is the current stage-gate of the scale-up. One article is from Chemical Engineering Progress and the other is a case study from BHS illustrating a process scale up from batch candle filtration to the commercial scale which required continuous vacuum filtration.

Finally, in the last issue, BHS announced our new and expanded testing laboratory in our facility in Charlotte, North Carolina. Capabilities include pressure and vacuum testing, cake washing, drying (blowing, pressing and vacuum), filter media selection, conductivity measurements, filter aid selection and other quality testing. We are now looking for a Lab Testing Technician; please see the side-bar for further information and to apply for this opportunity.

I hope that you find A&SoF useful and informative. Your comments, ideas and suggestions for future issues are much appreciated. If you missed any of the issues, please click on the following link: A&SoF, to view them. We look forward to your continued input.

Sincerely,

Sleuthing in Solid-Liquid Separation

Elementary, My Dear Process Engineers!

Back in 2013, I read Maria Konnikova’s book Mastermind: How to Think Like Sherlock Holmes. Solid-liquid separation may not have the glamor of investigating blackmail and burglary, extortion and espionage or mayhem, yet I was struck by the similarities between process engineers and Sherlock Holmes and Dr. John Watson. Process engineers, as do Sherlock Holmes and Dr. John Watson:

  • Know there is no benefit to jumping to conclusions.
  • Benefit from working with others
  • Apply problem solving skills to discern the crucial from the incidental.

CHEMICAL ENGINEERING PROGRESS

"Scaling Up Bioenergy Technologies"

David Edwards, Zeton Inc., Scaling Up Bioenergy Technologies, March 2015, pages 58 – 61, www.aiche.org/cep.

In this article, David discusses the stage-gate method for process scale-up. The focus of the article is bioenergy and he explains the differences between traditional chemical process scale-up and the scale-up for bioenergy projects. He covers each stage-gate of lab, pilot, demonstration and commercial and what are the key parameters to ensure success.

BHS ARTICLE

"Process Scale-Up from Demonstration Batch Filtration to Commercial Continuous"

This article will follow the process filtration approach developed for each technology stage-gate starting from batch filtration in the lab to continuous filtration for the full-scale commercial operation. The article begins with a discussion of each stage-gate and how to avoid the “cookie-cutter” approach to these types of projects. Laboratory / bench top filtration testing is covered for problem analysis, technology selection and pilot and demonstration scale-up. The paper continues with the filtration testing and then scale-up to the commercial size. Finally, the paper concludes with a general review of the problem-solving skills and how these skills can be utilized by process engineers as a framework for “idea-generation” when analyzing a new process scale-up.
