Oxygen

Oxygen (O₂) is a colorless, odorless gas with powerful oxidizing properties, essential for combustion, oxidation reactions, and life-support applications. At Messer, we supply both gaseous and liquid oxygen in a wide range of purity grades — from industrial to ultra-high-purity and medical oxygen — to meet the evolving needs of traditional industries and high-tech manufacturing alike. Backed by our extensive network of air separation units and on-site generation systems across China, we ensure a safe, stable, and uninterrupted oxygen supply for our customers. Oxygen plays a critical role in a variety of sectors. In metallurgy and steelmaking, it supports high-temperature combustion and converter operations, improving thermal efficiency and significantly reducing fuel consumption. In chemical and petrochemical production, oxygen is a key reactant in gas-phase oxidation, enhancing reaction kinetics and product selectivity — particularly in catalytic processes. In healthcare and life sciences, medical oxygen is essential for oxygen therapy, anesthesia, and hyperbaric treatments, directly contributing to patient outcomes and respiratory support. Beyond these fields, oxygen is also widely used in environmental and wastewater treatment, where it boosts aeration and biochemical degradation, raising dissolved oxygen levels and increasing treatment efficiency. In glass manufacturing and building materials, oxygen-enriched combustion helps raise furnace temperatures, improving both melting rates and final product quality. In electronics and semiconductor fabrication, high-purity oxygen is vital for plasma etching, oxidation, and other precision processes required in ultra-clean production environments.
