Modular and scalable solutions for Fenceline Monitoring

Modular and scalable, the WT1® fenceline monitoring system network is sized to your needs. Standalone analyser or sensor network results are available source by source, site by site or on a regional scale. For cities, large remediation sites, industrial areas, the WT1® fenceline monitoring system instrument network provides real-time accurate air quality data for efficient management of chemicals and olfactory pollution. Results can be accessed from the Ellona Software Platform secured website, using your web browser to access safely your data, 24/7, anywhere in the world.

WT1® fenceline monitoring system uses high-precision sensors for pervasive monitoring of pollution and nuisances. The concentration level (ppm or ppb) and sensor combination are defined based on the application requirements. The WT1® can be equipped with up to 6 gas proprietary electrochemical sensors including but not limited to H2S, NH3, mercaptans, SO2, CO, Ethylene Oxide, O3, Methane, Cl2 … in addition to the VOC (PID) and Particles PM measuring blocks.

Cloud SAS Based Hosting

The central monitoring station is hosted on a secure cloud based server allowing remote access via any internet based computer. The access is restricted and the data is encrypted for maximum security. Users are given a password and user name which will define their permission level. Operator access can simply view the results and create reports while administrator access can reconfigure the system and set all parameters

Graphic Emission Representation and Reporting

The monitoring system continuously provides real-time readings of all sensors in the grid plus has the capability to show data for any defined instance in time. Furthermore reports such as specified period mean, high, low and variance for each sensor can be shown. Other reporting options such as sensor ranking in highest average reading and highest variations

Typical Applications

Sulphur compounds, Volatile Organic Compounds are toxic and commonly targeted as odour precursors. Unlike the analysis of permanent gases, the analysis of sulphur gases is not easy because of their highly reactive nature. They tend to react not only with the materials they come in contact with but also with each other. In addition, volatile sulfur compounds are highly reactive and have absorptive, adsorptive, and metal-catalytic properties.

The
WT1® fenceline monitoring system is typically designed to measure continuously the concentration of 6 gases amongst an extensive list of air pollutants and odour precursors including but not limited to H2S, Mercaptans, Amines, NH2, SO2, CO2, CO, CL, C2HO4, H, HCl, HCN, NH3, O3, NO2, PH3, H2S, O2, SO2, CH4, NO, VOC, PM particles from 0,3 to 17 um.

WT1® fulfills the requirements of site operators and environmental authorities by providing an easily expendable fenceline monitoring solution for sites where odour management is critical such as wastewater treatment plants, paper mill, pharmaceutical facilities, refineries.

Landfills, Wastewater Treatment Plants

“Landfilling” is the main method for disposal of municipal and household solid wastes or refuses in Australia. Although maintained in an oxygen-free environment and relatively dry conditions, landfill waste produces significant amounts of odorific landfill gas mainly Sulphur gases. The WT1® fenceline monitoring system enables low and sub ppb levels monitoring of odour precursors S compounds from solid waste landfills, wastewater treatment and other waste recycling facilities.

Natural Gas Plant and Refineries

Petroleum gases and natural gas are well-established contributors to the world’s energy needs. Specialised sulfur compounds are produced for odorization of natural gas. The stockage, transport and processing of sulphur compounds leads to the need for scrutinised monitoring system to ensure the safety of the workers as well as accurate automated plant operations. In refineries the emissions from desulfurization processes are controlled accurately to prevent nuisances in case of degraded plant operations. The WT1® fenceline monitoring system provides plant operators with accurate and reliable sub ppb level continuous monitoring at site fencelines.

Pulp and Paper Industry

Pulp and paper mills occasionally emit certain gases into the atmosphere which are objectionable to the surrounding community. A group of these compounds referred to as total reduced sulphur (TRS) consisting of hydrogen sulphide (H2S), methyl mercaptan (CH3SH), dimethyl sulphide [(CH3)2S] and dimethyl disulphide [(CH3)2S2] are the principal culprits that are emitted particularly by the kraft pulping process. Government regulatory bodies issue guidelines to the industry banning their emissions above certain concentration levels.

The WT1® fenceline monitoring system analyses accurately, concentrations of these foul gases at source and in the atmosphere when dispersed from the stack.
