Propionic Acid Production from Propionaldehyde

This column is based on “Propionic Acid Production from Propionaldehyde – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/propionic-acid-production-cost. Propionic acid (also known as propanoic acid) is a carboxylic acid commonly found in nature, mainly…

Acetylene-selective MOFs for ethylene purification

Ethylene is an important petrochemical, but it may contain traces of acetylene that can destroy the catalysts used in downstream processes. The separation of ethylene and acetylene is difficult, and the main method, distillation, is energy intensive. A potential alternative…

Comprehensive connectivity and monitoring for heat-trace systems

Genesis Network (photo) is a new system that provides site-wide operational awareness and supervisory control of heat-trace systems. Users can easily monitor, maintain and troubleshoot even the largest heat-trace systems that may include over 10,000 heat-trace circuits. The Genesis Network…

Airset regulators for On/Off Valve Applications

Airset regulators are seemingly simple devices, but care must be taken to ensure the right devices are specified, particularly in safety instrumented systems Chemical plants and other heavy industrial facilities typically contain many pneumatically controlled valves, actuators and instruments. Airset…

Mitigate Dust Hazards With Good Equipment and System Design

By carefully considering equipment and plant design in processes involving powdered materials, fugitive dust issues can be reduced significantly Powdered ingredients that unintentionally leak from equipment in a manufacturing plant are known as fugitive dust. The risks associated with fugitive…

Industry’s first ‘four-in-one’ compact flowmeter

The new Rosemount 8800 Quad Vortex flowmeter (photo) is specifically designed to meet stringent safety standards in environments and applications that require safety instrumented systems (SIS). The flowmeter is said to be the first in the industry with quadruple sensors…

A new smartphone for hazardous areas

Last month, this company introduced the new generation of its intrinsically safe 4G/LTE Android smartphone Smart-Ex 02 (photo). With a large 5-in. display and smart ergonomics, the Smart-Ex 02 is said to be the most advanced explosion-proof smartphone for Zone…
