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…
Presented here are a few recent developments in filtration, including new cartridge design, automated self-cleaning systems and more Used for everything from purifying a liquid product, or recovering a solid product from a gas or liquid solvent, to environmental applications…
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…
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…
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 personal development strategy helps to set engineers up for success in their personal and professional lives As chemical engineers, we have been trained to be data-driven, fact-based problem-solvers. This focus serves us well when we are tackling difficult technical…
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…
