Rupture Disc Installation: Where to Place It
Rupture disc installation is not only a mechanical task but a hydraulic decision. This article examines how inlet line length, intermediate volume, and backpressure influence disc activation and overall relief system performance.
Bernoulli’s Principle: Equation&Applications
Bernoulli’s principle explains how pressure, velocity, and elevation are linked through mechanical energy conservation in fluid flow, with practical engineering applications and limitations.
Fluid Dynamics Basics for Engineers
Fundamental Concepts Governing Fluid Flow Fluid dynamics explains how fluids move, how pressure changes along a flow system, and why velocity increases or decreases when geometry changes. In this context, a flow system may be a pipe, a duct, a channel, or any connected path through which the fluid is transported. In chemical engineering, fluid dynamics… Read More »Fluid Dynamics Basics for Engineers
Decarbonization: VSD Pump Level Control
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.
What Is HAZOP Analysis? Example and Template
A practical HAZOP analysis example showing how deviations, causes, consequences, safeguards, and risk are evaluated using a real worksheet.
Hazardous Area Classification: ATEX Zones
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.
HAZOP Example: Material Compatibility Failure
Even water can lead to failure. This HAZOP example shows how overlooked piping material compatibility can cause loss of containment and safety risks.
Rupture Disc Activation: Near Miss or PS Event
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.
