Technology Profile: Isopropyl Alcohol Production from Acetone

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…

Multipurpose furnaces streamline loading and unloading

New GS2026 bench-mounted box furnaces (photo) include a spring-assist vertical-lift door that allows for effortless loading and unloading even at high temperatures. The furnaces are controlled by an industrial control system that includes a Eurotherm temperature control, overtemperature protection and…

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…

Level switches for dust collectors and more

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.…

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…

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…

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 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…
