碳氢化合物的检测和测量对于各种应用都是非常重要的，例如在石油和天然气工业中从提取到整个精炼过程，以及用于环境监测和便携式安全设备。本文介绍了一种高灵敏度，选择性，和强大的可调谐激光分析仪，有能力分析气体样品流中的几种成分。更具体地说，已经实现了用于同时检测C1至iC 5烃的多气体系统，该系统使用室温分布反馈带间级联激光器阵列，在3.3 µm波段发射。它结合了可调谐激光光谱法的所有优点，是一种快速、灵敏和选择性的在线多组分可调谐激光分析仪。该分析仪能够连续且以毫秒级快速监测工艺流中的C1-iC 5碳氢化合物成分，无需消耗品（例如，吹扫、载气），无需现场校准，从而降低了分析仪的拥有成本。该系统基于工业GasEye系列平台构建，并于2018年秋季首次在瑞典Lyseland的Preem炼油厂现场部署。测量活动的结果和比较与气相色谱仪器。
The detection and measurement of hydrocarbons are of high interest for a variety of applications, for example within the oil and gas industry from extraction throughout the complete refining process, as well as for environmental monitoring and for portable safety devices. This paper presents a highly sensitive, selective, and robust tunable laser analyzer that has the capability to analyze several components in a gas sample stream. More specifically, a multi-gas system for simultaneous detection of C1 to iC5 hydrocarbons, using a room temperature distributed feedback interband cascade laser array, emitting in the 3.3 µm band has been realized. It combines all the advantages of the tunable laser spectroscopy method for a fast, sensitive, and selective in-line multicomponent tunable laser analyzer. Capable of continuous and milliseconds fast monitoring of C1-iC5 hydrocarbon compositions in a process stream, the analyzer requires no consumables (e.g., purging, carrier gas) and no in-field calibration, enabling a low cost of ownership for the analyzer. The system was built based on an industrial GasEye series platform and deployed for the first time in field at Preem refinery in Lysekil, Sweden, in autumn 2018. Results of the measurement campaign and comparison with gas chromatography instrumentation are presented.
