Storage Tanks
Overview

Infrared thermography can be used for various storage tank applications. These include determining tank levels, finding the layers of different liquids and gases, and determining the amount of build-up.

Although these applications can be quite straightforward, there are a lot of factors which can cause errors or make the results inconclusive. It is important to understand the effects of enviromental conditions, curved surfaces of tanks, differing thermal conductivities, and both forced and natural convection in tanks.

1. Storage Tank Sludge and Bottoms

This image shows measurement of paraffin or sludge levels in a crude storage tank. Paraffin levels appear as a heat differential banding in the tank. The levels are quite high in this image, imaged and confirmed at almost 4 meters. There are also some bottoms (likely water, sand, rust, etc.) apparent in the lower portion of the tank.

Maverick Inspection Ltd. has provided international crude storage tank services including calculating volumes of paraffin.  We successfully work with contractors who provide cleaning services based on our information.

2. Disposal Water Tank
The different temperatures of the thermal mass in the tank and the water entering it are evident in this image. In drinking water systems, this phenomenon can reduce the water quality due to mixing and aging problems in distribution system storage facilities. For more information on drinking water studies you can contact Charlotte Smith & Associates, Inc.

3. Paraffin Levels

There is usually not just a simple layer of paraffin or other material in the bottom of tanks. Often there are also deposits on the walls of the vessels. These two heights can be confusing, and a good thermal contrast is required to differentiate between them and measure the sludge levels.

4. Tank Levels
If the conditions are right, tank levels can be very apparent and simple to measure with a thermal imaging system.

5. Water Tank Sludge Build-up
This storage tank required periodic cleaning to remove sludge levels from the bottom. Using infrared imaging technology, the cleaning schedule was easy to determine.

7. Tank Fire Simulation
Infrared cameras are excellent tools for monitoring the heat zone moving down a tank during an crude tank fire. Due to the importance of avoiding being caught in a boilovers during tank firefighting, Maverick has built a small simulation tank for training site personnel how to avoid making serious mistakes when using thermal imaging tools.
