人民气体和可乐公司（人民天然气）是芝加哥的天然气提供商。使用ABB的创新气体泄漏检测和定量系统，该公司成功地减少了甲烷排放，同时利用准确的泄漏检测来提高气管管道安全性。

人们的天然气为超过878,000个客户提供服务，并负责超过4500英里的气管遍布其服务领域。
凭借如此广泛的覆盖范围和如此多的客户，该公司必须确保对管道泄漏的快速检测，本地化和量化既限制甲烷排放，并确保芝加哥公民的安全。
People’s Gas is currently implementing an ongoing System Modernization Program (SMP), and as part of this, the company has approved a pilot program designed to employ advanced gas leak detection.
People’s Gas opted to employ ABB’sMobileGuard™ gas leak detection system作为该项目的关键部分，利用基于车辆的系统的功率和远程。
该系统具有ABB的LGR-ICOS™甲烷/Ethane Analyzer，这是一种全球定位系统（GPS）单元，一种声音气压计和高级软件，旨在检测泄漏，绘制其位置并量化排放。
Increased Range and Sensitivity
以前被人们气体使用的泄漏检测系统包括车辆甲烷泄漏探测器（VMLD），远程甲烷泄漏检测器（RMLD）和可燃气体指示器（CGI）的组合。
VMLD安装在车辆上，并提供1至1000 ppm/m的范围，灵敏度为0.1 ppm。RMLD能够检测到最多100英尺的气体，以每百万米（PPM-M）的零件报告。
The replacement of this system with ABB’s MobileGuard™ technology has led to a substantial improvement in terms of range and sensitivity. Detection is now possible down to single parts per billion at ranges of up to 600 feet.
The system’s rapid leak detection has enabled leak surveys to be conducted at standard driving speeds. It is also able to report both methane and ethane, allowing it to effectively eliminate false positives.
最关键的是，该系统可以对气体浓度，车辆位置和风速进行整理，以查明使用Google Earth的MAP功能显示结果，以查明潜在天然气泄漏的精确源位置和相对大小。
Collected data is integrated into the user’s geospatial information system (GIS), enabling comprehensive analysis and allowing the exact location of leaks to be determined with improved speed and accuracy.

Making the Most of the Data
With the capacity to pinpoint the source of emissions via MobileGuard™, People’s Gas has been able to effectively screen out other (non-pipeline) sources of methane and achieve an accurate estimate of lost gas over time.
The ability to use actual field measurements to quantify the impact of replacement programs on methane emissions offers a convincing and appealing alternative to reliance on industry averages by pipe size.

2018年进行的调查结果使人们的天然气能够在2019年优先考虑缓解活动，2019年调查的进一步结果支持2020年的情感优先级。该公司打算将来继续进行。
在2020年，该公司评估了在泄漏工作开始之前进行了调查的社区，发现施工后，实际上已经消除了排放，减少了95％至100％。
Peoples Gas’ first priority when planning construction is safety, but we can now overlay additional information gained from the advanced leak detection and quantification technology to prioritize neighborhoods with greater emissions and at higher risks.

Future Plans and Next Steps
People’s Gas intends to continue its use of theMobileGuard™系统，即使选择提前一年终止试点计划，以将技术直接纳入其SMP。
人们的天然气目前正在考虑和评估其他用例，包括提高其气体电源和大规模的外国气味评估过程。
