HELIUM ANALYSIS
HELIUM IN NATURAL GAS
Helium is typically found in natural gas deposits as a trace component. It is usually present in very low concentrations, ranging from a few parts per million (ppm) to a few percent, depending on the specific gas field.
The primary source of helium in natural gas comes from the decay of radioactive elements, such as uranium and thorium, in the Earth’s crust. These elements release alpha particles as they decay, and those particles can capture electrons from surrounding atoms, forming helium atoms.
Over millions of years, helium atoms migrate through the porous rock layers in the Earth’s crust and eventually accumulate in underground natural gas reservoirs. When natural gas is extracted, the helium is also released along with the gas, processed, and used for various applications, including scientific research, industrial processes, and medical applications.
Helium is a non-renewable resource, as once it is released into the atmosphere, it tends to escape into space due to its lightness. Therefore, helium recovery from natural gas sources is crucial to ensure its availability for future use.
TESTING FOR HELIUM
To test for the presence of helium in natural gas, several methods can be employed.
Gas chromatography is a widely used method for analyzing the composition of gas samples, including natural gas. The technique involves separating the different components of a gas mixture based on their interaction with a stationary phase inside a chromatography column.
In the case of helium detection, the gas sample is injected into the chromatograph, and the components are separated as they travel through the column. Helium, being the lightest component, typically elutes early in the analysis. The separated components are then detected by a detector, such as a thermal conductivity detector (TCD) or a mass spectrometer (MS). The detector signals the presence of helium in the gas sample, and the concentration can be determined based on the peak area or intensity.
THE VALUE OF HELIUM
Helium is considered a valuable commodity due to its unique properties and diverse range of applications. The scarcity of helium resources, coupled with increasing demand, has led to its relatively high market value.
Helium’s low boiling point and inert nature make it indispensable for various industries and applications. It is used in cryogenics, as a coolant in superconducting magnets for MRI machines and particle accelerators. It is also crucial for pressurizing and purging rocket fuel tanks, as well as for leak detection in critical systems.
In addition, helium has applications in the electronics industry, where it is used for cooling semiconductors during the manufacturing process. It is also employed in welding, as a shielding gas to prevent oxidation and ensure clean welds. The market value of helium is mainly determined by its critical applications and the challenges associated with its extraction, purification, and distribution.
