Infrared Thermography Surveys for the Oil, Gas & Petrochemical Industries
The Power Industries: Infrared Thermography plays a hugely important role within the oil,
petrochemical, chemical, and power generation industries. With the current global energy crisis, and the huge demand for energy on the increase, these energy-based industries must continue to meet higher volume demands while endeavoring to reducing operational costs and preventing failures. Such failures can lead to losses in production which in turn can cause massive monetary costs as well as ongoing effects that can be felt as far down as the consumer. This webpage will discuss the areas where Infrared Thermography is used within the petrochemical and energy sectors such as furnaces, generator cores, and offshore oil and gas platforms.
Introduction to Infrared Thermography in the Petrochemical Industry: The petrochemical industry is a fascinating, varied and challenging industry in which to carry out the many different types of nondestructive testing and predictive maintenance inspections. Within any refinery complex there numerous plants that carry out a specific function and process; and within each plant there is a multitude of equipment from steam powered, to hydraulic, electrical & mechanical. There is positive/negative pressurized equipment and a varied amount of exotic metals and alloys. The terminology used to simplify this is “the Balance of Plant”. Experienced inspectors know, the words “balance of plant”
simply mean you must be prepared to meet the confusing and unexpected.
When we think of petrochemical plants and operations we usually think of an oil refinery; however, the process of oil refining is undertaken in multiple stages. There are separate chemical plants within a petrochemical refinery, and usually, where there is a region of petrochemical and hydrocarbon activity, there are also other forms of process or chemical plants such as methanol, ammonia, etc. Due to the complexities of this I will undertake a brief explanation of each area:
The main function of an offshore separator is to quickly separate sand, water, oil, and gas. We know that out of these four materials, sand sinks in water while oil floats, and gas is light and cold and will remain on top. Also, each of these materials has a very different thermal capacitance and conductivity making it possible to use Infrared Thermography to locate and highlight the relative levels of solids and fluids.
Using thermal images we can distinctively differentiate between the layers of sand, water, oil, and gas. We can even see the sand’s flow pattern through the outlet nozzles, which can help to determine which valves will be more affected by the erosive power of sand.
Our Infrared Thermography engineers undertaking thermographic surveys for separator sediment levels have a firm understanding of fluid dynamics, thermodynamics, and erosion mechanisms, along with a good understanding of heat transfer, emittance, and reflectance. With this knowledge our Infrared Thermography engineers are qualified to make accurate diagnoses which in turn leads to proper, cost-effective means of minimizing the problems or, hopefully, eliminating the problems. It may be something as simple as packing gravel/stone in the well to reduce the flow of sand, thus alleviating the overall mass travel of sand and as a result reducing the wear on valves etc.
Power Generation Plants: Pressure, heat, and natural gas are used to spin gas turbines, which in turn spin the generators; this generates electrical power through electromagnetism. Within the turbine section, heat leaks can be found at the gas seal areas of a turbine. This inspection can be carried out online.
Gas Turbines and Heat Leakage: The generator section contains a stator and rotor. Both can be inspected with Infrared Thermography, however the generator needs to be offline and disassembled. This type of survey is frequently done when the stator needs to be repacked. Stator cores are made of iron bars which contain many small thin plates called laminations. Both the stator and rotor can be inspected with Infrared Thermography by wrapping several coils with insulated cables along the axis of the stator. Then, a pre-calculated amount of current is applied through the coils in order to generate a suitable flux.
A Smoothly Flowing Plant: Much of the power distribution within petrochemical plants goes towards driving motors, pumps and compressors. This rotating equipment is vital to a plant’s operation and can be thought of as a plant’s heart whose job it is to pump, compress, pressurize, and cool down the various fluids that maintain the plant’s production. Infrared Thermography inspection of rotating equipment is very common.

INFRARED THERMOGRAPHY IN INDUSTRY
Thermography is the use of an infrared imaging and measurement camera to "see" and "measure" thermal energy emitted from an object.
Infrared energy, is light that is not visible because its wavelength is too long to be detected by the human eye; it's the part of the electromagnetic spectrum that we perceive as heat. Unlike visible light,
in the infrared world, everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared. The higher the object's temperature, the greater the IR radiation emitted. Infrared allows us to see what our eyes cannot.
