So, the CCS process can be thought of as returning CO2 to its underground home.Īccording to Australia’s National Hydrogen Strategy, which was published in November of 2019, there are several high potential onshore CCS locations in Australia, principally in Queensland and New South Wales. Many CCS schemes plan to use depleted natural gas reservoirs for the long-term storage of CO2, thereby refilling them with a gas that they previously contained. When the natural gas rises from the underground gas reservoir, it is generally accompanied by large quantities of CO2 which has existed with the methane in the underground gas field for thousands of years. SMRs and ATRs are most commonly fed with natural gas which is rich in methane. CCS is an integral part of these schemes to ensure that they produce blue hydrogen and play a role in sustainable decarbonisation. Several new projects have also been proposed to construct steam methane reformers (SMR), or auto thermal reformers (ATR) to produce large quantities of hydrogen for heating and mobility applications. Atmospheric emissions of CO2 from existing combustion processes, such as cement production or electrical power generation can thereby be reduced to slow down climate change. These are designed to meet the high quality standards required for specialty gases and can deal with high and low pressures plus high and low flows.The concept of Carbon Capture and Storage (CCS) is to recover carbon dioxide (CO2) from industrial process gas emissions and inject the CO2 deep into the ground for long term storage. We also provide certificates of analysis so you have proof of these exceptional quality attributes.Ĭomplementing this offering, we have a range of gas pressure regulators and gas distribution systems for high-purity zero gases such as these. Our zero gases spanning synthetic air, nitrogen, hydrogen, argon and helium range in purity from 5.0 up to 7.0, which is the highest commercially available grade (99.99999% pure with 0.1 parts per million of total impurities). These developments demand precise calibration gas mixtures and ultra-high- purity zero gases.Īt Linde, we understand that the reliability of gas analysis is only ever as good as the quality of the instrumentation gases, the accuracy of the calibration gas mixtures and the purity of the zero gases used. Increasingly accurate measurements of both product quality and emissions from industry are required. Consequently, the need to set an accurate zero point has become more important than ever. Legislation governing pollution and industrial emissions has tightened in recent years, as has fiscal monitoring for oil and gas trading. Impurities occurring in concentrations as low as parts per billion can have serious consequences, particularly if the impurities are part of the sample to be analysed or if the analyst is not sure which molecules are present in the sample. Contamination of zero gases can significantly influence the results of analytical measurements. The purity of the zero gas used to set the zero point on analytical instrumentation is critical and must be sufficiently high for the application in question. Non dispersive infrared (ND-IR) spectroscopyĮmission testing for on-road and off-road vehicles and machineryĪ zero gas is normally a pure gas that does not contain the component to be measured, and it should be as similar to the matrix of the measured sample as possible.
