Distillation Back Mixing: Impact on Batch Yields
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…
‘I do not believe in entrainment’
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…
Flexible separators for hazardous areas
This firm’s decanters and disc-stack centrifuges assume a key role in the mechanical separation operations in the chemical and pharmaceutical industries, including clarification of liquids, classification of solids, and dewatering liquid-solid suspensions and liquid-liquid separations. The firm’s decanters and disc-stack…
A new spray dryer for laboratories
The MobileMinor Basic spray dryer (photo) is said to meet all the basic requirements of laboratories, especially those in small companies and universities, and other laboratories that don’t need many of the options available for the advanced MobileMinor models. The…
Save time and expense with this new drying system
Radio Frequency The Macrowave radio frequency (RF) drying system heats filter cake material uniformly to remove water without overheating. The drying system is a suitable replacement for tumble, spray, tray, spin flash and belt/tunnel dryers, and can reduce labor and…
Keep your Process Clean with this New Filter Housing
The new line of 222 Giant Industrial Filter Housings and Cartridges (photo) promises sub-micronic filtration at low cost and high surface areas for throughput and is protected by a unique, double 222 O-ring seal for process integrity and safety. The…
New Line Of In-line Filters
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…
Optimize spray drying with this simulation tool
Developed over the last three years, Drynetics is a concept for using computer simulations to optimize a spray drying plant (photo). The model is put into the computational fluid dynamics (CFD) simulations of full-scale spray dryers, and incorporates the know-how…
This centrifuge combines filtration and solids drying
Robatel This laboratory or pilot scale centrifuge (photo, p. 32 D-6) offers centrifugal filtration and solids drying in a single machine. It is equipped with interchangeable rotors to allow its use as a horizontal basket centrifuge, and as a tumble…
This pump inlet trap is adaptable to changing processes
MV Products The PosiTrap Vacuum Inlet Trap product line (photo) is designed to protect pumps in small production and R&D applications up to 50 ft3/min. The filter elements are available in a variety of specialized media that are easily changed…
