Two new sizes of turbomolecular pump introduced
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…
A skid-mounted RO system for high-purity water production
Through its business unit Solys, this company launched the Sirion Pro range, a simplified version of the Sirion RO (reverse osmosis) range (photo). A compact, plug-and-play system that integrates Aquavista digital services, Sirion Pro offers more basic features — a…
This turbidity sensor withstands aggressive media
The new Turbimax CUS50D sensor (photo) is an absorption sensor for turbidity and suspended-solids measurement in unfavorable environments. Its robust design is made to withstand aggressive media and is suitable for applications in industrial wastewater treatment or chemical processes. Turbimax…
Leak detector for easy and accurate ‘sniffing’ operations
This company has launched the ASM 306 S (photo), which addresses any industrial leak-detection “sniffing” applications, especially in refrigeration and air-conditioning processes. This new leak detector is highly sensitive (10 –7 mbar L/s), precise and accurate. Leakage control using sniffing…
Access and control flowmeters from a smartphone
Edge Flow Electronics (photo) interface with positive-displacement or turbine flowmeters to provide better access, understanding and control of processes — in some cases, from a smartphone. When installed on a flowmeter, Edge devices can force the sensor to output a…
Facts at your Fingertips: Cyclone Separators
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…
Controlling Reboilers Heated by Condensing Steam or Vapor
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…

Isopropyl alcohol (also known as isopropanol or 2-propanol) is a colorless and flammable liquid with a…
Seal Considerations to Reduce Fugitive Emissions
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…
A Simplified Approach to Crystallization Mass Balances
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…
