The accuracy of an NO gas sensor, the primary component of NOx, can be compromised when exposed to ambient temperatures above 86°F (30°C) and significantly more so above 104°F (40°C). To help prevent this temperature effect on the NO sensor,…
The new SP series (photo) is a so-called “air-over-oil” filter press driven exclusively by compressed air. Air-over-oil filter presses are used where power connection is not available or possible in a process line. By deliberately dispensing with electrical equipment, the…
Liquid-level measurement in storage tanks or other vessels is important for avoiding spillage and process upsets. One class of technologies for liquid-level measurement involves measuring the pressure exerted on a gage by the weight of the liquid, and this one-page…
This column is based on “Ammonia Production from Natural Gas – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/ammonia-production-cost. Ammonia (NH3) is among the most important industrial chemicals, produced by reacting nitrogen and hydrogen in…

Last month, special recognition to water-related issues was given on March 22, the date designated by the United Nations as “World Water Day.” The first World Water Day was observed in 1993, and has been celebrated every year since. The…
Detection of gases is a critical task in many chemical process industries (CPI) facilities to avoid hazards to personnel and to the environment. Gases may present risks of explosion, flammability, toxicity, environmental pollution and displacement of breathable air. This one-page…
This column is based on “Bio-based Adipic Acid Production from Glucose – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/adipic-acid-production-cost. Adipic acid is one of the most commercially important aliphatic dicarboxylic acids. It is produced…
Researchers from the Agency for Science, Technology and Research (A*STAR, Singapore; www.a-star.edu.sg) have developed low-cost, environmentally friendly iron-hydroxide coatings with unique fin-like shapes that absorb large amounts of pollutants, such as dyes, from drinking water, by means of a simple…
Today, ammonia continues to be manufactured by the Haber-Bosch process — an energy-intensive process that operates at high temperatures and pressures (above 400°C and 100 bars). For decades, researchers around the world have been looking for alternative routes to making…
