Blending is a fundamental chemical unit operation, and there are a handful of common ways to implement it. Blending applications can be either manual or automated, and can be carried out either as a batch or continuous process. There are…
This column is based on “Diammonium Phosphate Production – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/diammonium-phosphate-production-cost. Diammonium phosphate (DAP) ranks among the most important phosphate-based fertilizers, not only for its high nutrient content, but…
Characterizing mixer impellers on the basis of power, flow, shear and efficiency Mixing has been defined as “the application of mechanical motion in order to create fluid dynamic effects that achieve a desired process result” [1]. The process result is…
Utilizing ‘Tolerance Intervals’ can help to set more realistic specification ranges, especially when only small amounts of data are available Specifications provide a framework by which one can gage whether products have been manufactured successfully. They identify a product’s key…
When installing rupture discs, there are several mechanical and operational considerations for reducing the likelihood of leaks and fugitive emissions Overpressure relief systems consisting of rupture discs and relief valves are vital for preventing damage and injury within chemical processing…
Integrated console, virtual-reality simulation offers learning for maximum, measurable training efficiency Modern techniques are being used for realistic plant training for control room operators, field operators, and operations and maintenance personnel. Simulator training has been shown to result in better…
Successful operation of safety valves in steam systems requires careful adherence to established industry standards for installation and design One of the most critical safety devices in a steam system is the safety valve. Figure 1 is an illustration of…
The physical properties of zeolites make them extremely important in many industrial processes. This one-page reference provides information on the structure and chemistry of zeolites that allows their use in the chemical process industries (CPI). Zeolite structure Zeolites are a…
This column is based on “Prilled Urea from Ammonia via Self-Stripping Process – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/urea-production-cost. Urea is a nitrogenous compound consisting of a carbonyl group attached to two amine…
This mature technology can be used to save energy, generate revenue and reduce emissions With the Paris Agreement entering into force last November, the Parties to the Convention established their goals to implement measures to reduce the amount of greenhouse…
