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 …
Ventilation is necessary in confined space entry to ensure safe breathing conditions for personnel working inside tanks, vessels, and other enclosed spaces. In this article, we will discuss what are the types of ventilation in confined space entry and share my experience with the ventilation selection on the shop floor. What is Ventilation in a …
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 …
Precision matters a lot when it comes to designing as a simple mistake can lead to a big issue in the industry. A small error in flow rate, density, or heat balance can cause inefficiencies, increase costs, or compromise safety. As a chemical engineer, I have faced various problems and spent lots of time in …
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 …
