1. Industry Background
With the continuous advancement of China's dual-carbon strategy and deep optimization of its energy structure, natural gas, as a clean and low-carbon energy source, has seen its application scale expand significantly in industrial production, urban gas supply, energy storage and transportation, and has become an important part of China's energy system. At the same time, the state has increasingly strict quality control, operation and maintenance, and environmental compliance requirements for the entire process of natural gas extraction, purification, transportation, and end-use. Numerous industry standards have been introduced, mandating that natural gas companies must achieve real-time monitoring of parameters such as component content, impurity concentration, and calorific value indicators to prevent environmental hazards related to the delivery of substandard gas sources, gas leaks, and excessive emissions.
There are numerous pain points in the current operation and maintenance monitoring of the natural gas industry: traditional manual sampling and testing methods are outdated, cumbersome to operate, and prone to large errors, making them unsuitable for the needs of continuous industrial production; outdated monitoring equipment has weak resistance to interference, poor data stability under high temperature, high humidity, dust, and complex pipeline conditions, and struggles to capture key impurity parameters such as hydrogen sulfide, carbon dioxide, and non-methane total hydrocarbons; most equipment has limited functionality, unable to perform multi-component simultaneous analysis, remote data transmission, and intelligent early warning, making it difficult to meet the demands of modern, intelligent, and compliant production management. For XX Environmental Protection Technology Co., Ltd., which has been deeply involved in natural gas environmental monitoring and industrial gas treatment, there is an urgent need for a high-precision, high-stability, intelligent, and integrated natural gas analysis system to address monitoring shortcomings, improve project service quality and industry competitiveness, and meet the requirements of high-quality market development and compliant operations.
2. Product Introduction: Xi'an Runlai RL-607 Natural Gas Analysis System
The Xi'an Runlai RL-607 Natural Gas Analysis System is an integrated, intelligent online monitoring system independently developed by Xi'an Runlai Instrument Co., Ltd. in response to the pain points in the entire natural gas monitoring process. It is specifically designed for natural gas purification, pipeline transportation, storage and distribution stations, industrial gas terminals, and other scenarios, and can meet the full range of needs for natural gas component analysis, impurity monitoring, calorific value detection, early warning, and data traceability. It is currently the mainstream equipment in the fields of natural gas environmental monitoring and production quality control. The core of this system is the tunable diode laser absorption spectroscopy technology (TDLAS), paired with a high-precision thermal conductivity detector (TCD), and equipped with a dual-gas path sampling and six-way valve automatic sampling architecture. It can detect the content of various core components in natural gas such as CH₄, C₂H₆, C₃H₈, CO₂, H₂S, and non-methane total hydrocarbons, while simultaneously calculating the calorific value and purity of natural gas. The measurement range can be flexibly customized according to on-site conditions, with measurement accuracy ≤±1%FS and repeatability ≤±1%FS. The detection data is stable, far exceeding the standards of conventional industry equipment.
In terms of equipment structure and protection design, the RL-607 system uses all-stainless steel piping and valves, which are corrosion-resistant, wear-resistant, and have strong sealing properties, suitable for complex and harsh industrial conditions, effectively avoiding monitoring errors and hazards caused by gas leaks and pipeline corrosion. The equipment features an integrated cabinet design with a neat layout, small footprint, and convenient installation and commissioning, suitable for various factory and pipeline station deployment needs. It also incorporates multiple intelligent protection mechanisms, including over-temperature automatic power-off alarm, carrier gas cut-off/leak protection, and intelligent temperature tracking and regulation functions, which can effectively protect core components such as chromatography columns and detectors, significantly reducing equipment wear and extending service life.
In terms of intelligent operation and maintenance, the system is equipped with a high-definition on-site display terminal that provides real-time and intuitive display of various monitoring data, while also outputting standard 4-20mA current signals. It can seamlessly connect to enterprise DCS control systems, remote monitoring platforms, and data recorders, enabling real-time upload, remote viewing, automatic storage, and traceability of monitoring data, supporting unattended operation, and completely freeing from the inefficient traditional manual monitoring and recording mode. Compared to traditional monitoring equipment, this system offers multiple advantages such as multi-functional integration, high accuracy, strong stability, easy operation and maintenance, and wide adaptability, meeting the core needs of the natural gas industry for environmental compliance, production, and intelligent management.
