This company’s Continuous Processors (photo) feature a proprietary design that ensures the fast-reacting materials used to process rigid polymeric foams are mixed, gelled and reacted entirely within the sealed reactor barrel before they begin to cure. Allowing foam formation and…
The new CSA Range of sealless pumps (photo) are designed for handling high-temperature, toxic, flammable, corrosive, carcinogenic and aggressive fluids. The sealless magnetic-drive designs eliminate emissions and leaks, which can harm productivity, personnel and the environment. The new CSA Range…
The DJ level switch (photo) provides high- or low-point level detection of bulk solids. The DJ detector operates successfully on baghouses, cyclone separators and above airlocks. Consistent results have been achieved on chemical powders, minerals and many other granulated materials.…
This company has expanded its Turbovac i/iX series of turbomolecular pumps with the addition of two new sizes — the 850 i/iX (photo) and 950 i/iX. The two new pumps are characterized by extended operation, longer system life and lower…
Removing solids from a stream of air or other gases is an important operation across virtually all sectors of the chemical process industries (CPI). In many cases, gas-solid separation is motivated by the need to reduce environmental impact and health…
The new Flexifeeder line of flexible screw conveyors (photo) offers expanded capability with less frequent maintenance. Each Flexifeeder is matched to the individual user requirement, using both this company’s extensive installation database and complementary laboratory testing. The use of controlled…
This column is based on “Isopropyl Alcohol Production from Acetone – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/isopropyl-alcohol-production-cost. Isopropyl alcohol (also known as isopropanol or 2-propanol) is a colorless and flammable liquid with a…
Methods for controlling reboilers in distillation towers are central to good reboiler operation and tower stability. Control valves can be located in the steam-inlet line or in the condensate-outlet line. This article updates guidance for key considerations and practices using…
By understanding the basics of industry standards, such as API 682, plants can make great strides in controlling fugitive emissions related to equipment seals Chemicals that unintentionally leak from equipment into the atmosphere are known as fugitive emissions. These gases…
In continuous crystallization, it is often challenging to accurately measure mass flowrates, but the method described here enables a simpler path to a balanced crystallization process To gain optimal value from industrial crystallization processes, it is clear that understanding specific…
