Variable Speed Drive (VSD) pumps with level control can reduce energy consumption and support industrial decarbonization. This article explains how the technology works, shows practical examples, and highlights the role of chemical engineers in achieving sustainability goals.
A practical HAZOP analysis example showing how deviations, causes, consequences, safeguards, and risk are evaluated using a real worksheet.
Understand the fundamentals of ATEX zone classification for gases, vapours, and mists according to Directive 1999/92/EC. This article explains where the classification applies, how to interpret Zones 0, 1, and 2, and what to consider for equipment such as pumps, piping, and tanks — including internal volumes.
Even water can lead to failure. This HAZOP example shows how overlooked piping material compatibility can cause loss of containment and safety risks.
When a rupture disc activates, it represents a process deviation that must be recorded within the Safety Management System. Depending on the outcome, it may be classified as a near miss, a contained release, or an incident requiring further investigation.
Joule’s experiment demonstrates the equivalence between mechanical work and heat, providing the experimental foundation of the First Law of Thermodynamics and the concept of internal energy.
The five main unit operations in chemical engineering are Heat Transfer, Mass Transfer, Mechanical Operations, Fluid Transport, and Membrane Separation. These categories form the foundation of industrial processes, from energy recovery and separation to particle handling and fluid distribution.
Definition and Scope of Chemical Engineering Chemical engineering is the discipline responsible for designing, analyzing, and operating industrial process systems that transform raw materials into finished products under controlled, safe, and economically viable conditions. It is not defined by laboratory glassware or isolated chemical reactions.It is defined by the ability to make complex systems function reliably… Read More »What Is Chemical Engineering?

What is the Distillation Process? Distillation is a method used to separate the components of a liquid mixture by exploiting differences in their volatility. When a liquid mixture is heated, part of it vaporizes. The vapor phase is richer in the more volatile components, while the remaining liquid becomes enriched in the less volatile ones.
