Online analysis of odourants

Jon Lawson

When odour issues occur at an industrial site, rapid diagnosis must be done and a strategy defined to treat odour sources definitively. Today, the sensory panel approach using dynamic olfactometry analysis is considered as first approach to rank odour sources and subsequently to treat the most noxious odours. When investigating the source of the odour, an online monitoring system provides for the best available methodology.

In response to this need, Chromatotec has developed the solution for the online analysis of odourants with sulfurs speciation in addition to VOCs monitoring including ammonia (NH3). Chromatotec solutions provide the ability to quantify concentrations in parts per billion (ppb) or parts per trillion (ppt) in ambient air and process applications. Its all-in-one, turn-key, vigi e-nose solution can be deployed at any location, any environment, and any classification where odourant monitoring is required.

CANOPIA recovery center located in Bayonne, France, has recently deployed Chromatotec’s solution. This site collects domestic waste from 200,000 citizens and converts it to compost, solid recovered fuel and biogas by utilizing the VALORGA methanization process. Urbaser Environment designed and managed the construction of the entire site and currently manages the site through the VALORTEGIA subsidiary.

The vigi e-nose analyzer is part of vigiOdor solution developed for online monitoring and modeling of the site contribution of the olfactory and chemical impact of the site on neighborhood. vigiOdor is the web platform fed by data provided by vigi e-nose and local meteo weather station. As new capabilities, it integrates spot measurement using sensory data (EN 137125 method). It allows for site mitigation procedures to treat and prevent odours with better understanding of process variations based on-line reliable and validate results. It facilitates communication with authorities’ and associations.

Mr. Cueillens, Project Director for Urbaser Environment, in charge of the site management, states “We were looking for a solution able to monitor sulfurs and VOCs to facilitate our understanding about process variation. This was not possible with sensors-based electronic nose technology as such solutions did not help us to elaborate diagnosis of process malfunctions when odor concentration exceedance was observed on the effluent of the odour control system. Today, the Chromatotec solution with vigiODOR platform and vigi e-nose GC based technology give us the expected results.”

Chromatotec will present this solution during Achema – booth G86 Hall 11.1
