Odour measurement via olfactometry is expensive and has a low accuracy compared with chemical or physical methods. In addition, olfactometry is not suited for online monitoring. Hence, an accurate online method for emission measurement would be an enormous improvement. There are several options to more or less replace the offline olfactometry by online measurement available today. Most common are H2S-concentration as a single gas parameter and VOC and TOC as composite parameters. A fairly new development are multi sensor arrays, usually referred to as "electronic noses" which carry out non-specific gas measurement and deliver measurement data that can visualized as a fingerprint diagram. This paper outlines the use of these different parameters and compares the results to those gained via olfactometry of several case studies.
与化学或物理方法相比,通过嗅觉测量法进行气味测量成本高昂且准确性较低。此外,嗅觉测量法不适用于在线监测。因此,一种准确的排放测量在线方法将是一项巨大的改进。目前有几种或多或少可以用在线测量替代离线嗅觉测量的选择。最常见的是将硫化氢浓度作为单一气体参数,将挥发性有机化合物(VOC)和总有机碳(TOC)作为复合参数。一个相当新的发展是多传感器阵列,通常被称为“电子鼻”,它可以进行非特定气体测量,并提供可以可视化为指纹图谱的测量数据。本文概述了这些不同参数的使用,并将结果与通过嗅觉测量法在几个案例研究中获得的结果进行了比较。
