Push-to-connect in-line filters introduced
This new line of in-line filters (photo) can be easily connected and disconnected for service on tubing applications. Designed with John Guest push-to-connect style fittings integrated into the Celcon plastic filter housing, this unique in-line filter product line offers versatility…
This membrane module can be cleaned by backwashing
With a membrane area of 10 m 2 and a 10-kD molecular weight cutoff, this new Flow-Cel module (photo) is optimally designed to filter protein-containing liquids with high solids content. The key feature of this cassette system is the ability…
A new, mineral-free depth filter medium
This firm has developed the bepure process, in which different types of high-purity cellulose are crosslinked to form a structure that does not require the addition of any inorganic material, even for sterile filtration duties. BecoPad P (photo) is characterized…
A new decanter generation for food-and-drink applications
The F Series represents a new generation of decanter. The GCF 405 is designed for products that are difficult to discharge, which makes it suitable for use as a clarifying decanter in brewing and beverage industries. The multifunctional machine with…
New, efficient decanters for environmental applications
Efficient acceleration of the product in the feed zone combined with an optimized discharge system enables the new C-Series environmental decanter line to boast a reduced power consumption of up to 20–30% for capacities of 20 to 90 m3/h. This…
FRI’s parallel projects
Considering that Fractionation Research, Inc. (FRI) has been performing distillation research since 1954, don’t we have all the answers yet? Not according to the membership. The vendors of trays and packings have had very aggressive R&D programs. New and interesting…
Crow’s nest
The fact that I was 150 ft up, on the outside of an extraction column, in January, in Canada, in a 20-mph wind, was not the worst part of the experience. The worst part was that the column was not…
S-L separation: No more separation anxiety
Given the state of the still-lagging economy, it doesn’t come as a surprise that the chemical process industries (CPI) are attempting to get more finished product from their existing processes at lower costs. As a result, many are examining their…
Earthquake fractionation
Some columns sway with the wind; some columns sway with the waves. In fact, hundreds of columns now reside offshore, on platforms and on barges. Most dry and sweeten gases. Some distill. The trays and packing distributors of such columns…
Reboiler Circuits For Trayed Columns
The reboiler generally supplies most of the energy required to effect component separation. If too much heat is supplied, the tower may flood; conversely, if too little heat is available, separation performance may decrease via poor reflux ratio (pinching), excessive…
