High spec, clean tech – Specialty gases in environmental protection


Bob Brown, the Australian politician once said, “The future will either be green or not at all.” As we seek to maintain our industrialised way of life in a sustainable way, employing clean technologies and high specification industrial gases has become critical and will become more so.

With this as the backdrop, it is no surprise that BOC Australia has recently announced the investment of AUD$20m to upgrade its Wetherill Park specialty gases manufacturing facility. Chris Dolman, Business Manager Specialised Markets at BOC Australia in Sydney, commented, “We live in a beautiful country with natural wonders like the Great Barrier Reef and the Gondwana rainforest which can only survive if we protect the cleanliness of our air, soil and water. But we also suffer from significant problems, for example reduction of the ozone layer which is caused by pollution created all over the globe, so environmental protection has become a real priority for Australia and at BOC we are proud to be making world-class specialty gases that are part of the solution to this problem.”

Specialty gases, related gas control equipment and analytical instrumentation all play essential roles in environmental protection. From the use of synthetic air in the analysis of TOC levels in waste water to the use of high purity argon in ICP instrumentation for drinking water purity assay, specialty gases are in use daily. Measurement of heavy metal and organic chemical contamination in soil is also an area where specialty gases are consumed. Furthermore, high precision specialty gas mixtures play a critical role in analytical techniques that are required to protect the quality of the air we breathe.
