Hot work on process equipment is one of the highest-risk activities in chemical plants and refineries. The risk increases significantly when Hot work such as welding, cutting, or grinding, has to be performed on non-decontaminated lines or vessels containing hydrocarbons or flammable vapors. In this article, I’m sharing my practical experience using mud plugs for …
In reaction kinetics, the Arrhenius equation is commonly used to explain how temperature influences reaction rates. To make these calculations easier, we’ve built this Arrhenius Equation Calculator. It allows you to determine the rate constant (k), activation energy (Ea), or the pre-exponential factor (A). Apart from this, we have posted various chemical engineering calculation tools …
In chemical plants, gases are everywhere in reactors, compressors, and storage systems. To design these processes safely and accurately, engineers need to understand how gases behave under different pressures and temperatures. The Ideal Gas Law works well for simple conditions, but in real operations, gases often behave differently. That’s when Real Gas Equations, like the …
As a chemical engineer working in industries, I often come across equipment where heat transfer is happening continuously, whether it’s in heat exchangers, reactors, furnaces, or cooling systems. There are three modes of heat transfer: conduction, convection, and radiation. In this article, we will learn the types of heat transfer with examples and laws. Before …
This free online tool will make it easy to check the pH or ion concentration of a solution. Just enter your data and get instant results for pH, pOH, [H⁺], and [OH⁻]. pH Calculator Calculate pH, pOH, [H+], and [OH-] concentrations From Concentration From Acid/Base From pH From pOH Info: Enter the concentration of H+ …
Heat exchangers are widely used in industries such as chemical, dyes and pigments, pharmaceuticals, and many more. They help transfer heat between two streams. However, after some duration, the heat transfer rate decreases, and one reason is fouling. In this tutorial, we will learn about Fouling in Heat Exchangers, its types, and its causes. What …
