Pneumatic conveying is a versatile method for transporting powders and other solid materials within chemical process plants. Success depends on understanding science and applying specific experience Undergraduate engineering programs include little instruction about powder handling. While there may be some…
Fractional crystallization is a stage-wise separation technique that relies upon the liquid-solid phase change and enables the purification of multi-component mixtures, as long as none of the constituents can act as a solvent to the others. Thanks to the level…
When it comes to water used in boilers, it is important to remove potentially problematic impurities. This offers a potentially huge return on investment, even with the prevention of just one major upset, let alone recurring failures Several decades ago,…
Five common mistakes associated with implementing predictive maintenance tools are discussed here, along with five ways to avoid them Predictive maintenance (PM) implementation can be a daunting task. There are many factors to consider and many ways that things can…
By minimizing, or even eliminating, the need for blowdowns in steam systems, precoat filter demineralizer systems can greatly contribute to water-conservation efforts Steam is essential in any chemical process plant, primarily for generating heat and power. Power generation (the largest…
Stainless steels are common materials for process equipment and components in the chemical process industries in large part because of their corrosion resistance. This one-page reference reviews the properties of stainless steels with regard to corrosion resistance. Passive layer Stainless…
Safety is often underestimated when planning, operating and maintaining process-measuring equipment. Sensors with SIL certification, alone, do not make the process safe. It is important to avoid systematic errors during planning, installation and operation The correct installation of a temperature…
Thoughtful design can help reduce safety risks at process plant sites by proactively eliminating possible hazards and modifying personnel behaviors Safety is an important value in any organization, but is particularly important in the chemical process industries (CPI) when the…
A routes-by-exception reliability strategy helps improve safety and efficiency, while preserving competitive advantage in a changing marketplace In recent years, maintenance and reliability experts have often talked about the massive wave of retirements leaving chemical plants, creating a shortage of…
In a typical bulk-solids pneumatic-conveying system, an air mover is used to generate the necessary air flowrate and pressure required to transport a solid material through a pipeline at a given rate. This one-page reference discusses the operating mechanisms and…
