This issue will focus on “New Challenges Demand New Processes”

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) and successful.  We have received “likes” and “comments” from the marketplace.  The most recent blog is described below.  We are looking for guest bloggers to contribute.  Contact me through the link on the blog and let me know your ideas.  You can also tweet me @baperlmutter. Thanks for your help to make this successful.

This issue focuses on new challenges in the chemical, pharmaceutical and oil and gas industries and the development of new processes.  One article is from ACHEMA 2015-Decision Briefs and the second is from SEFAR AG, a leading filter media supplier.  The BHS blog discusses how BHS has met an “offshore….yes, an offshore challenge.”  

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,

Barry A. Perlmutter

Sleuthing in Solid-Liquid Separation

BHS is Now Offshore!

For the transport of Liquefied Natural Gas (LNG) in pipelines, monoethylene glycol (MEG) is added as corrosion inhibitor and to reduce the freezing point of the water in the LNG.  The MEG is then reclaimed.  The reclamation unit normally contains a of ph-adjustment step, allowing the divalent salts to precipitate after adding sodium hydroxide and seeding crystals.  The salts and other contaminants can be removed from the rich MEG prior to entering the thermal regeneration section.  BHS installed a three (3) candle system with 198 m2 of filter area to remove these contaminants.

"Process Development –New Challenges Demand New Processes"

By Dechema,

From the lab to the industrial process can be a long way – simulation tools and modern methodology help to shorten it.  Despite their innate conservatism, the chemical, pharmaceutical, oil and gas industries are always looking for new products that are more effective than those they replace, or cheaper, more environment-friendly routes to existing products. Developing a new process can take up to a decade and requires co-ordination between professionals from several different cultures, often spread across the globe. In this article, examples are provided illustrating challenges and developments.    Read More….  
 

"FILTER MEDIA PERFORMANCE AND ITS INFLUENCE ON FILTRATION RESULTS- EXPERIENCE, EXPECTATIONS AND POSSIBILITIES IN VACUUM AND PRESSURE FILTRATION "

By Delia Bartholdi, Isabell Erlenmaier, Alexander Seitz, Christoph Maurer, Sefar AG: 
 
 
Current demands and trends in various liquid-solid separation applications require that the filter media be adjusted to the specific product characteristics and process requirements of the user. In the past, the industry had the choice between two types of filter media: one with low resistance, providing a high level of permeability, but with lower mechanical strength; or one with higher resistance, resulting in a lower level of permeability, but mechanically strong and stable. Concessions had to be made, especially for the use in vacuum or pressure filtration. Design and characteristics of the filter media, such as number of pores, pore shape, pore size, pore size distribution and permeability, are all influencing the cake formation, cake filtration, filter media lifetime, as well as the resulting machine efficiency and productivity. Ultimately, these factors affect the overall cost of ownership. 
 
This paper will highlight and describe the variables and performance criteria that require definition in order to properly select the most efficient filter media for a given application. Filter media utilization and resulting filtration capacity, filtrate clarity, the media’s influence on cake dryness, and cake release, are discussed.  Read More Under the Subheading “Filter Media Technology”
