The steam reforming process is a highly efficient technology for hydrogen production from methane. In this application, acquiring high-purity methane and removing odorant compounds from natural gas are crucial for ensuring the quality of the final product. To accurately assess the effectiveness of the deodorization process, it is necessary to monitor the concentrations of the sulfur compounds removed during the gas treatment process.

Chromatotec’s solution enables the quantification of hydrogen sulfide (H₂S) across two concentration ranges:

• High Range: Direct measurement of H₂S concentration in the natural gas pipeline at low ppm levels.
• Very Low Range: Measurement of H₂S concentration after the deodorization process at low ppb levels.

The system is designed with two sampling loops of different volumes, allowing the analytical device to automatically switch between sampling modes. This mechanism prevents signal saturation while maintaining high accuracy during monitoring, thereby enhancing the effectiveness of natural gas quality control and optimizing the hydrogen production process.
