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.…
Designed for new or existing separator and distillation tower operations, the Uniflow Inlet Diffuser can correct flow imbalances and improve gas distribution with a geometry that dissipates high inlet-gas velocities and evenly distributes gas in the vessel. By maximizing the…
Raise your hand if you ever regretted going with the low cost bidder. Keep your hand raised if the low cost bidder ever yielded you the highest cost result. If your officemate is staring at you quizzically, pretend to be…
The 7710 Series filters are designed to deliver high value for filtration applications using lower-pressure liquid and gas. The filters have porous metal elements and 316 stainless-steel housing. A range of seals are available to support applications requiring higher temperature…
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…
[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 AFR Series Tubular Backwash Filter System is designed for continuous, high-flow filtration (single system flow rates 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…
