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…
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…
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…
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…
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…
Facing a site security audit might seem daunting, but proper preparation will help to meet the goals of enhancing security and reducing risk What are the downsides of failing to pass a security audit or inspection? Is it the fear…
This practical overview of ASTM standards can serve as a roadmap when selecting and evaluating heat transfer fluids Heat-transfer-fluid systems are often used for process heating to 500°F or higher. To accomplish heating above 500°F, steam pressure must be above…
Working with supercritical fluids poses challenges when designing heat exchangers. Some practical tips and precautions are presented here Industrial applications involving fluids at high pressure — pressure above the critical pressure of a particular fluid — are increasing in number.…
