This issue will focus on “Batch & Continuous Filtration”   

Welcome to Year Number 8 of A&SoF. As we look back on the eight years, one fact remains the same:   sometimes filtration is more “art” than “science”.  This year A&SoF will focus on the art of filtration through case studies and creative problem solving.

It is also year 3 of my blog (  I’ve already started thinking with excitement about 2017’s blog posts such as Ford Motor & Tequila, Famous Nathan’s Hot Dogs and many others over a variety of topics. Yet I invite you to make suggestions! In fact, I’d welcome guest blogger contributions. Please let me know what interests you. I’d be happy to discuss it further.
This issue focuses on the challenges of continuous processing as well as batch filtration and removal/clarification examples.  Finally, BHS is undertaking a collaborative project to look at the relationship of filter aids, filter media and filtration technologies.  If you would like to contribute with ideas, let us know.    
As always, thanks again, to our readers, for your feedback and if you missed any issues, please click on the following link:  A&SoF, to view them.   Our goal this year is to further strengthen the knowledge in the marketplace and encourage conversations with the many authors, bloggers, tweeters and experts from our industry.

Ford Motor & Jose Cuervo Tequila

How are Ford Motor & Jose Cuervo Tequila related….sustainability.  In a typical car, there are over 400 pounds of plastic parts.  Ford began researching the use of sustainable materials in its vehicles in 2000. Today, the automaker uses eight sustainable-based materials in its vehicles including soy foam, castor oil, wheat straw, kenaf fiber, cellulose, wood, coconut fiber and rice hulls. 
The growth cycle of the agave plant, for Jose Cuervo, is a minimum of a seven-year process. Once harvested, the heart of the plant is roasted, before grinding and extracting its juices for distillation. Jose Cuervo uses a portion of the remaining agave fibers as compost for its farms, and local artisans make crafts and agave paper from the remnants. 
Ford and Jose Cuervo have just announced a partnership to explore the use of agave fibers for bioplastics that can be used for certain car parts.

Process Development SYMPOSIUM - PDS 2017 

The 2017 Process Development Symposium is a conference organized by AICHE to exchange wisdom, knowledge, tips, and personal experiences in the development and scale-up of chemical and related processes.
One session is “Transitioning from Batch to Continuous Processes”.  The benefits of continuous versus batch chemical processes are well established - including higher product throughput and yield, lower space requirements and capital investment, faster product changeover, more consistent quality, and the ability to safely run reactions at more extreme conditions. BHS will be presenting at this session illustrating how one client transitioned from batch candle filters to continuous – indexing vacuum belt filters.  Read More….  

BHS “Ground-Breaking” Study Combining Topics of Filter Aid, Filter Media and Filtration Technologies

In the literature and the filtration marketplace, you find information on filter aids, filter media and filtration technologies.  Each topic is written by industry experts and suppliers but is focused inward; there is no one looking to the marketplace.  The process engineer must gather this information, make their own comparisons and then develop a process solution.  BHS sees this as a void in the market and is now undertaking a ground-breaking step to develop a comprehensive approach to filter aid usage, filter media and wrapping all of this into filtration technology selection.  Our research and testing is now underway with a completion date of August 2017.  If you would like to contribute or have ideas to get involved, let us know...

New Approaches for Removing Catalyst Fines From Chemical and Pharmaceutical Slurries

BHS has authored a new technical paper that reviews coarse particle filtration, existing equipment for catalyst fines removal / recovery and then covers new approaches of candle and pressure plate filters including testing and selection.  Three case studies are illustrated (1) Raney Nickel Catalyst, (2) Pharmaceutical Hydrogenation, and (3) Palladium Catalyst Filtration, Washing and Drying.  Read more …
