Demystifying Flame Arrestors: Understanding Pressure Drop Calculation

Flame arrestors are important safety devices used in many industries to prevent the spread of fires and explosions. They are typically installed in the piping system of tanks, pipelines, and other process equipment that contain flammable liquids or gases. One of the most important aspects of understanding and maintaining a flame arrestor is calculating the pressure drop across it.

What is a flame arrestor?

First, let’s define what a flame arrestor is. A flame arrestor is a device designed to prevent a flame or explosion from spreading from one part of a piping system to another. Simply put, it acts as a barrier to prevent the spread of fire. When a flame or explosion occurs in a tank or pipeline, a flame arrestor prevents the flame from returning to the system, thus preventing a larger explosion or fire.

Why is it important to calculate the pressure drop across a flame arrestor?

The pressure drop across a flame arrestor is the difference between the pressure on the inlet side and the pressure on the outlet side of the device. It is important to determine this pressure drop because it directly affects the performance of the flame arrestor. If the pressure drop is too high, it can lead to operational problems such as reduced flow and increased risk of equipment damage.

How to calculate pressure drop across a flame arrestor?

When calculating pressure drop across a flame arrestor, several factors come into play, such as the type of gas or liquid being transported, the size and type of flame arrestor, and the design of the piping system. This is a complex calculation and to obtain accurate results, it is important to use data and equations from reliable sources.

Tips for calculating pressure drop across a flame arrestor:

• Use accurate data: Make sure you have the correct data for the gas or liquid being transported and the type of flame arrestor being used.
• Use standard industry equations: Industry organizations provide equations and guidelines for calculating pressure drop across a flame arrestor. Make sure you use them to get accurate results.
• Consider the type of flame arrestor: Different types of flame arrestors have different pressure drops. It is therefore important to understand the type and design of the flame arrestor in order to calculate the pressure drop accurately.
