The gas chromatographic revolution for gas networks

PicoGC is an automatic gas chromatography solution designed for the continuous and remote determination of the odorants levels in fuel gases. The instrument quantifies the level of THT (tetrahydrothiophene) or TBM (tert-butyl mercaptan) odorants.

The Instrument makes it possible to enhance the efficiency of the natural gas transportation and distribution grid, leading to reduced operating costs, minimized waste, and a significant improvement in safety.

Analysis system for a smart management of gas distribution networks

Currently, most of the work for verifying and controlling the quantity of odorant is carried out via portable micro gas chromatographs installed on specialized mobile vehicles, which periodically analyze the level of odorization at the Odorant Measurement Points. This entails significant operating costs in staff, equipment and consumables (vans, portable μGC, carrier gas and standard cylinders, etc.), but above all a prolongued interval between one measure and the following (every six months) resulting in periods of time when the concentration is unknown.

PicoGC is a micro gas chromatographic solution that automatically collects field data online and enables remote process management. The robust design, ATEX Zone 1 certified, allows the device to be permanently installed at critical points in the natural gas grid to measure the concentration of various odorants (THT or TBM) in the flow. The compounds are analyzed, and the data are transmitted in real-time to the customer’s SCADA (Supervisory Control And Data Acquisition) and/or Cloud system or to our proprietary cloud platform Pollution Guardian.

The high level of automation and remote connectivity capabilities enables the optimization of the entire process, offering numerous advantages over traditional methods, including:

  • Higher production efficiency and significant time savings compared to conventional laboratory techniques due to the analysis frequency
  • High sensitivity and selectivity to ensure precise and reliable results, even at very low concentrations of odorants, thanks to the proprietary Thermal Conductivity Detector (TCD) technology
  • Cost savings while maintaining required safety levels
  • Prevention of potential overestimation of losses by users, resulting in reduced costs associated with emergency management
  • Significant reduction in costs related to the purchase and handling of odorants
  • Minimisation of the risk associated with high sulfur content, which could lead to pipe corrosion and air pollution.

The complete solution for measuring odorants quantity in fuel gases consists of two elements:
