Natural gas operations in the UK and Ireland require precision instrumentation to ensure safety, efficiency, and compliance in hazardous environments. From odorization dosing and calorific blending to custody transfer and emissions sampling, every process demands reliable control and accurate measurement. Intrinsically safe devices are essential for Zone0 applications, while advanced regulators and Coriolis meters support pipeline integrity and billing accuracy.
This page highlights key applications and the technologies that make natural gas systems safer and more efficient.
Odorization ensures natural gas is detectable for safety. Dosing mercaptan or odorant requires precise flow control under varying line pressures. Hazardous area compliance is critical because odorant injection points are often in Zone0 environments. Instruments must handle corrosive chemicals and maintain dosing accuracy to prevent over- or under-odorization, which can lead to safety risks or regulatory non-compliance.
Blending gases to maintain calorific value ensures consistent energy delivery. This process requires precise multi-gas control and fast response to maintain Wobbe Index targets. Hazardous area compliance is essential for blending stations located in classified zones.
Fuel gas supply to boilers and burners must remain stable during load changes. Pressure and flow fluctuations can cause combustion inefficiency and increased emissions. High-pressure capability and hazardous area compliance are critical.
Continuous emissions monitoring systems require stable sample-line pressure for accurate analyzer readings. Pressure fluctuations can compromise compliance data and audit results.
Gas chromatograph and CEMS systems often need automated stream switching and purge control. Dual-valve architecture simplifies extraction and venting in hazardous areas.
Leak testing and purge verification are critical for safety during maintenance and commissioning. Instruments must measure low differential pressures accurately without disturbing system integrity.
Measuring flow in high-pressure natural gas lines within Zone0 requires robust, intrinsically safe devices that deliver accurate data for process control and compliance.
Pilot lines on dome-loaded regulators require stable sensing and control to maintain downstream pressure. Intrinsically safe transducers ensure compliance and reliability.
Injecting nitrogen or air for BTU correction requires low ΔP control to avoid disturbing pipeline pressure. Intrinsically safe controllers ensure safe operation in hazardous zones.
Reducing pipeline pressure safely and reliably is essential for distribution networks. Self-operated regulators provide simple, robust control without external power.
Maintaining upstream pressure in odorant skids and blending systems prevents process disruptions. Back-pressure regulators ensure stability under varying demand.
Custody transfer of LNG, LPG, and odorants requires high-accuracy mass flow measurement for billing and compliance. Coriolis technology delivers unmatched precision.
