This column is based on “Ammonium Nitrate Porous Prills Production Process – Cost Analysis,” a report published by Intratec Solutions. It can be found at: www.intratec.us/analysis/ammonium-nitrate-production-cost. Ammonium nitrate (NH4NO3) is one of the most commercially important ammonium compounds, both in…
Understanding the effect of flowrate, velocity, density, viscosity, pressure drop, friction, components and sample line sizes will help you design a sampling system The primary goal when designing an analytical sampling system is to ensure timely, accurate measurements. The sooner…
Although waste is unavoidable in industrial processes, many companies are turning toward business strategies that seek to treat waste with minimal environmental impact — or even better, prevent waste altogether In the past, waste was simply discharged without any treatment.…
Normalized profitability metrics provide a basis for comparing the efficiency of capital investments, but they are often misunderstood. New interpretations of these metrics can help engineers to make more informed decisions In a financial sense, a large capital project can…
Agglomeration converts fine powder particles into larger ones by introducing external forces. Major benefits for solids processors include dust reduction, easier handling, more complete utilization of raw materials and densification. Agglomerating particles happens by a variety of means, including mixing…
This column is based on “Ethylene Oxide Production from Ethylene – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/ethylene-oxide-production-cost. Ethylene oxide (also known as EO, oxirane and epoxyethane) is the simplest cyclic ether. Because it…
Lessons learned from past failures provide insight and know-how needed toinspect and operate storage tanks reliably Storage tanks are a common sight at many facilities of the chemical process industries (CPI). Tanks are part of our everyday life and they…
Using the approach outlined here, piping engineers can select the most appropriate bolt-tightening technique based on pressure class and flange size, and calculate the required torque or tool pressure if hydraulic tensioning tools are used In the majority of industrial…
Software that enables complex processes to be simulated continues to evolve for a wide range of thermodynamic conditions. Selection of the most appropriate models plays a crucial role in adequately representing real-life conditions One of the first and most important…
Among the key benefits offered by pneumatically conveying bulk solids is the ability to route materials around obstructions in the plant using bends in the pipeline. However, these changes in direction involve a considerable number of particle impacts on the…
