This company has been issued two new patents on its next-generation nozzle-based cleaning technology systems for reverse pulse-jet dust collectors. Because of the specialized design of the nozzles, the company says its dust collectors operate sucessfully at lower rates of…
Syrris In March, this firm signed an exclusive agreement with Prosonix. By combining Prosonix’s ultrasound technology with the Atlas jacketed reactor platform, the Atlas SonoLab SL10 sonocrystallizer enables the reproducible control of crystallizations and allows selectivity of parameters, such as…
Freudenberg Filtration Technologies The new Viledon Compact pocket filters of the T90, MF 90 and MF 95 series feature a four-layer medium and an integrated nanofiber layer, which achieves “superlative” filtering performance by means of mechanical assistance coupled with a…
Due to their simplicity of construction, lack of moving parts, ability to operate at a wide range of temperatures and pressures, low capital and operating cost, cyclones have been the workhorse for gas-solid separation in a wide variety of industries.…
[Originally published in the May 1995 issue of Chemical Engineering] Cyclone dust collectors have been used - and misused - all over the world for more than 100 years. One reason for the misuse is a common perception among users…
It was the Dr. James R. Fair Heritage Distillation Symposium at the Chicago AIChE meeting last month. I had decided to finally give a presentation about something that has been bugging me since October 28, 1974, my first day as…
The Witte Co. This salt-drying system recycles hot exhaust air Among a host of advantages, the bulk salt-dryer system (photo) from this company captures half of its hot exhaust air for recycling, which both reduces energy requirements and cuts the…
Several case histories illustrate the benefits of identifying and correcting poorly designed reflux and product-handling systems Manufacturers of specialty chemicals are routinely required to reduce costs and increase the production of their high-value products. Specifically, competitive pressures from the developing…
The ongoing scaleup of numerous microfiltration plants has increased demand for filtration modules with large membrane surface areas — a demand adequately met by the new Microdyn and Seprodyn tubular modules, MD220 TP 2L (photo) and SE220 TP 1L. While…
The AFR Series Tubular Backwash Filter System (photo) is designed for continuous, high-flow filtration (single-system flowrates up to 2,000 gal/min and 454 m 3 /h). The system is designed to replace a much larger eight-station tubular multiplex system in a…
