Core Viewpoint - The successful implementation of domestically produced trace sulfur analyzers in natural gas purification plants marks a significant step towards the localization of critical analytical equipment, enhancing production stability and quality assurance [1][3]. Group 1: Equipment Performance and Features - The newly installed domestic trace sulfur analyzer has been operational for over 60 days, demonstrating accuracy and stability in production [1]. - This analyzer measures hydrogen sulfide, carbon monoxide, and methyl mercaptan content, ensuring the quality of natural gas products by monitoring the desulfurization process [3]. - The analyzer utilizes laser detection technology for hydrogen sulfide, offering high sensitivity and fast response times, while the ultraviolet fluorescence method for total sulfur analysis ensures accurate output with linear error, repeatability, and zero drift all less than ±2% S [5]. Group 2: Project Background and Future Plans - The development of the trace sulfur analyzer is part of a group-level research project aimed at the localization of key online analytical instruments for high-sulfur purification units, with the project now entering the conclusion and acceptance phase [3]. - The natural gas purification plant plans to further optimize the operation and maintenance costs of the joint unit and enhance its autonomous operational capabilities, providing reliable support for the efficient and clean development of domestic high-sulfur gas fields [7].
