Comprehensive Guide to High-Purity Gas Control

High-purity gases are the unsung heroes across various industries, serving functions from equipment preservation to gas line purging. Their handling, however, demands specialized products designed to maintain their purity level and ensure safe gas distribution. This task comes under the scope of high-purity gas control.

This blog will discuss the crucial aspects of high-purity gas control, highlighting its importance, potential challenges, and its role in diverse industrial sectors.

What are High-Purity Gases?

Gases that have very low levels of impurities are high-purity gases. They are refined to be composed almost entirely of the intended gas molecules. The level of purity of these gases is typically above 99.995% and can exceed 99.99999%. These gases are graded based on the number of 9s in the purity level. For example, a gas with a level of purity of 99.999% is considered grade 5.0, whereas a grade 4.5 refers to 99.995% purity.

Importance of High-Purity Gas Control

High-purity gas control equipment is specially designed to ensure seamless flow and management of pure gases with no margin for error.

Safety: Safety is of critical importance while handling some of the compressed high-purity gases, due to their flammable, toxic, oxidizing, or corrosive nature. From source to process, a vast range of gas control equipment like manifolds, pressure regulators, and valves ensure safe gas delivery without leaks.

Purity: In some sectors, even the lowest impurity can render the expensive ultra-high-purity (UHP) gas obsolete. Ultra-high-purity gas control equipment maintains the purity of the gases by preventing contamination from moisture, dust, and other gases present in ambient air, ensuring desired results, and avoiding wastage.

Industries Relying on High-Purity Gas Control

Laboratories and Pharmaceutical

High-purity gases are pivotal in a laboratory setting specifically for pharmaceutical and medical research applications. They are used as carrier gases for chromatography or as blanketing gases to protect sensitive samples from contamination. Precise flow, control, and adjustment of these gases are needed to create stable and effective results.

Automotive

The usage of high-purity gases has seen an increase in the automotive industry. From process control to calibrating analysers, high-purity gases are used abundantly in the automatable manufacturing process. Thus, high-purity gas control is crucial for this industry.

Semiconductor and Electronics

Semiconductor and electronics industries make use of high-purity gases in various production stages of microchips, integrated circuits, and other electronic components. It is necessary to maintain the purity level of the gas during purging, annealing, plasma etching, and blanketing applications to ensure optimal performance of the manufactured devices.

Petrochemical

In the petrochemical industry, high-purity gases are essential for processes such as catalytic cracking and polymerisation. Maintaining gas purity ensures the efficiency and safety of chemical reactions, leading to higher quality end products and preventing contamination that could disrupt the production process.

Laser and Plasma Cutting

High-purity gases like nitrogen, oxygen, and argon are critical in laser and plasma cutting operations. These gases help achieve precise cuts, reduce oxidation, and improve the overall quality of the finished product. Proper gas control ensures consistent performance and minimises the risk of defects.

Marine

In the marine industry, high-purity gases are used for applications such as welding, cutting, and equipment maintenance on ships and offshore platforms. Ensuring the purity of these gases is vital to avoid corrosion, ensure strong welds, and maintain the structural integrity of vessels and infrastructure.

Food and Beverage

High-purity gases are used in food and beverage industries to lock the freshness, colour, taste, and shelf life of food products. Food manufacturers are increasingly making use of nitrogen, oxygen, and carbon dioxide gases to preserve foods over conventional chemical additives as a healthier alternative.

Power Generation and Environmental Monitoring

In recent years, hydrogen has played a key role as a fuel cell technology for electricity generation as an efficient power generation alternative. High-purity gases also play a role in hazard and safety monitoring by identifying leaks in pipelines and power plants. They also help to fine-tune and calibrate various analytical and testing instruments used for monitoring air and water quality.

Challenges in High-Purity Gas Control

Contamination and Leakage

High-purity gases are susceptible to contamination when exposed to the ambient air, rendering them unusable for sensitive applications like semiconductor manufacturing. Leakage of hazardous and flammable gases also poses serious safety risks. Using quality high-purity gas control equipment is essential for the safe and effective delivery of these gases.

Material Compatibility

The materials used in the construction of regulators, valves, and piping systems must be compatible with the harsh properties of high-purity gases. Choosing the right equipment that resists chemical reactions, corrosion, and material degradation ensures longevity and safety.

Precise Control

Accurately controlling and maintaining the pressure of high-purity gases under exacting conditions can be challenging. Utilizing advanced pressure regulation systems and monitoring equipment is crucial to ensure consistent pressure levels. This stability prevents pressure fluctuations that could negatively impact the process outcomes or safety.

Regulatory Compliance

Handling of high-purity gases is often subject to stringent regulations that can drastically vary across different regions and industries. Staying compliant with these evolving standards requires continuous adaptation of processes and equipment.
