High-resolution 3D-printing makes small, structured parts

Manufacturing of centimeter-sized test specimens for material characterization according to ISO standards has now been achieved for the first time with a technology that allows 3D-printing a feature size of 200 nm. UpNano GmbH (Vienna, Austria; www.upnano.at) succeeded in printing…

Low-maintenance, heavy-duty flexible conveyors

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…

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…

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…

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…

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…

Isopropyl alcohol (also known as isopropanol or 2-propanol) is a colorless and flammable liquid with 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…

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…
