Systech Taps Orbital to Collaborate on Case Study
In September 2010, Orbital installed the gas monitoring and treatment plant on the UK’s very first large-scale bio-methane-to-grid production facility. This site was designed specifically to provide a renewable energy supply by generating bio-methane for injection into the existing gas network. The facility at Didcot, Oxfordshire, generates bio-methane by the anaerobic digestion of waste from the on-site sewage plant. Since this first installation, Orbital has supplied bio-methane-to-grid systems for various producers in multiple geographies.
The bio-methane-to-grid sector has seen a significant expansion in the UK since 2015. Approximately 60 to 70 bio-methane projects have been completed, providing enough gas to meet the heating and cooking requirements of around 340,000 homes.
Orbital uses the EC91 ATEX oxygen analyser from Systech Illinois to accurately monitor the oxygen content in the purified bio-methane gas prior to it being injected into the national grid gas network. This weather-proof, intrinsically safe oxygen analyzer is ideal for use in biogas and other renewable energy sources such as syngas produced by gasification or pyrolysis processes. It is ATEX certified for installation in Zone 0, 1 and 2 hazardous areas with a robust IP65 weatherproof enclosure and stainless steel remote sensor. The instruments long-life oxygen sensor is suitable for continuous use and is compatible with methane, hydrogen, carbon dioxide and mild acidic gas type samples.
“Orbital has worked with Systech instruments for many years, particularly in regard to utilizing Systech’s oxygen measurement instruments within Orbital’s analysis systems. The instruments have proven to be robust and accurate in service, with excellent after-sales support provided by the team at Systech,” said Peter Read, of Orbital, business area manager – unconventional gas.
The accurate measurement of oxygen is an important component when considering gas quality, he said. Bio-methane gas must comply with legislative requirements to be allowed entry into the gas network. Using the EC91 ATEX instrument allows us to integrate a cost-effective, reliable and accurate instrument for oxygen measurement. We have used the EC91 for a number of years in the UK natural gas network prior to the emergence of the bio-methane-to-grid market. With our experience of the EC91, it was a natural fit with our bio-methane-to-grid solutions.
Orbital has 19 installed bio-methane-to-grid network entry units in the UK with a 100% record of achieving successful gas on date.
“Our success is owed to the quality of our solutions, people and the products, such as the EC91 ATEX, that we incorporate into our systems,” Read said.
