About Oxygen

Commercial oxygen has many applications. It is used to support and intensify combustion in glass and steel furnaces; as a feedstock for chemical and metallurgical oxidative reactions; to purify wastewater; to bleach paper pulp and oxidize black liquor; and to process sewage — to name just a few.

Production and Distribution Network

Liquid oxygen is produced by the fractional distillation of liquefied air. Each gas oxygen, nitrogen, argon, neon, krypton, xenon has a different boiling point. Gases are separated based on their different boiling points in a distillation column.

BOC Gases operates 33 air separation plants nationwide with capacities up to 2,800 tons per day. These plants currently produce and deliver to our customers more than one million tons of oxygen each year. All BOC air separation plants are, or are in the process of becoming, ISO 9002 registred.

The BOC National Scheduling Center operates round-the-clock to accommodate both scheduled and emergency deliveries. Our TEL-TANKTM telemetry system enables BOC and our customers to remotely monitor liquid levels, ensuring timely deliveries.

With more than 650 retail locations, BOC has the largest distributor network in the industry, providing our customers with a reliable local source of supply.

Service and Engineering Support

BOC Gases employs hundreds of service specilists and engineers at customer service centers in dozens of cities nationwide.

We can tailor an oxygen supply method based on volume, purity, pressure, power costs and other key parameters. Our engineers can design, engineer, install and maintain the most efficient, cost-effective supply solution for your particular application. In addition, BOC Gases offers a wide range of equipment and systems designed to enhance productivity at the point where oxygen is delivered and used in your process.
