Urea Nitrogen-Based Fertilizers: A Fuel for Growth

GEA Ecoflex Plate Heat Exchangers Prove Their Worth in Fertilizer Plants

The world’s population is expanding rapidly, and so too are its energy requirements. Providing food for almost seven billion people, and reducing our dependence on crude oil by using plant-based energy sources, require the targeted use of fertilizers. The production of nitrogen-based fertilizers is a chemically complex process in which heat is repeatedly transferred between the process media. As the world’s leading fertilizer plant engineering company, Uhde relies mainly on plate heat exchangers from GEA Ecoflex.

New Hart Loop Converter Increases the Performance of 4…20 mA Field Devices

A new Hart Loop Converter converts up to three digital Hart variables that could include the 4…20mA transmitter current signal and makes them available to the host control system. These three variables enable not only the actual measured result but also process-related parameters such as reaction-time and temperature to be determined and used selectively to control the process — using the same cable and incurring no extra cost.
