"A move to automated measurements, via wireless technology, has offered greater process visibility for one gas storage operator which has allowed it to work much closer to capacity. RWE Gas Storage is an underground gas storage operator in the Czech Republic, operating six facilities with a total capacity of almost three billion cubic metres. Gas is stored in porous underground facilities during low-off take periods and supplied to users when demand peaks. The facility has active operating reserves of 900 million cubic meters with a current maximum daily output of 15 million cubic meters and is supplied by 47 production wells via an underground pipeline. Incoming gas is filtered and metered, then compressor units generate the necessary injection pressure. After the gas cooling process, the gas is pumped through high-pressure pipes into wells connecting to the storage caverns. The company is continually looking to improve the overall effectiveness of its underground gas storage facilities as measured by the maximum daily input and output. To improve the total amounts required better control, which required higher visibility into the process. However, manually reading over 100 pressure and temperature measurements took around two hours every shift. Having so many manually read gauges was a particular problem when the gas injection rate was higher. This required manual supervision along the entire pipeline, which utilised most of the operations resources. Automating these measurements would give operators greater visibility into the process and increase their efficiency, which would enable them to perform other, more important activities. As well as gaining access to diagnostic data from existing control valves new online pressure, temperature and level measurements were required. Improved visibility to the process would enable operators to run the facility closer to capacity minimising downtime by detecting problems that would, otherwise, lead to unplanned maint
