For the first half of my career, I worked in a group that developed, designed and sold distillation trays. Late during the 1970s, half of that group’s business disappeared — almost overnight — when structured packing replaced trays in very…
Sterilizing-grade filters from this company have all-metal construction, and can perform filtration that meets the requirements of ASTM standard F838-05 for bacterial retention. The sintered, porous-metal filter media products are biocompatible, impervious to solvents and can be used with most…
Introduced to the Spanish market last month, the Targa II hollow-fiber ultrafiltration cartridge is suitable for a wide range of ultrafiltration applications, including industrial water treatment, seawater pretreatment and tertiary wastewater treatment. The element features robust polyethersulfone (PES) membranes that,…
Distillation is one of the most extensively used operations in the chemical process industries (CPI). It is a highly energy-intensive unit operation, and continuously rising energy costs make it imperative to look for ways to reduce energy requirements. Some energy-saving…

The GFD (glass filter dryer) FilterBox containment system is a small-scale solution to this company’s larger FilterBox products. The FilterBox consists of an agitated nutsche filter dryer (ANFD) or GFD completely integrated within a PSL isolator, providing high containment when…
Limited budgets and the need for high performing operations are causing chemical processors and petroleum and gas refiners to seek out the best bang for their capital dollar. And when it comes to gas processing operations, such as carbon-dioxide removal,…
The Larox VPF (vertical pressure filter) is used for the pregnant liquor polishing stage in the alumina process, producing both a high-quality product and a high throughput. Low impurity in pregnant liquor is required for further production of metal-grade alumina.…
At the Chicago AIChE meeting last spring, Henry Kister and Mike Pritchett named the distillation symposium in honor of James R. Fair, who had recently passed away. Fair was probably best known for his leadership of the Separations Research Program…
Many chemical processes in the U.S. that use centrifuges were established between the 1950s and the 1980s. As a result, most of these machines employ technology that was outdated literally generations ago. In addition, many processes have changed since installation,…
