Evaporators: Design Concepts and Equipment Selection
This primer provides guidance on key aspects to consider when designing and specifying evaporators, which are used in a diverse array of industrial sectors Industrial evaporators are used to remove a solvent from a non-volatile solute to obtain a concentrated…
Technology Profile: Production of ammonium nitrate
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…
Facts at your Fingertips: Removal of Particulate Matter from Industrial Processes
Controlling and reducing particulate matter pollution from industrial operations is a key environmental and human health objective. In chemical process industries (CPI) facilities, airborne particulate matter can result from combustion of fuels, or from process operations, such as dust from…
Avoiding SIL Misconceptions
Engineers must refine their foundational understanding of process safety in order to avoid common misconceptions about safety instrumented systems, including safety integrity level (SIL) definitions Learnings from major industrial process accidents occurring over the past half century have driven awareness…
Interpreting Normalized Profitability Metrics
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…
Selecting the Right Thermodynamic Models for Process Simulation
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…
Technology Profile: Ethylene oxide production from ethylene
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…
Facts at your Fingertips: Agglomeration Processes
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…
How a Waste Treatment Plan Can Improve Your Bottom Line
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.…
Storage Tanks: Snapshots of Failures, Damages and Inspections
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…
