Software Products


www.opsis.se

• Monitoring the air quality for compliancewith directives/guidelines

• Monitoring fugitive industrial emissions

• Providing a fast and sensitive gas alarmsystem

Three functions in one package:

The Fence-line Monitoring Concept


www.opsis.se

Configuration Example


www.opsis.se

• Provides useful information on general air quality, but also on specificindustrial fugitive emissions.

• Provides useful information for air quality management and ISO14000 compliance.

• Will give extensive information on export and import of gaseouscompunds to and from neighbouring areas.

• Provides alarms in case of gas leaks or accidential releases.

• Detection and actions against gas leaks and fugitive emissions costsavings.

Features of Fence-line Monitoring


www.opsis.se

Fence-line monitoringusing 3 × 3 DOAS paths

Case Study – Biferno, Italy


www.opsis.se

• The problem: Several industries in a valley creating high pollutionlevels.

• The objectives: Finding efficient monitoring techniques that can beused for monitoring multiple paths and a large number of gascompounds, and a software tool for managing obtained data.

• The solution: Advanced monitoring stations in a fence-lineconfiguration using DOAS open-path monitors in combination withEnviMan software.

Why Choosing Opsis?


www.opsis.se

Type of industries and fugitive Emissions:

• Automotive – Formaldehyde, HC

• Sugar factory and refinery – NOx, SO2, H2S

• Various chemical industries – Phenols, CS2, NH3

• Food industry – Various HC

Industries and Emissions


www.opsis.se

DOAS:SO2, NO2, NO, O3, NH3, Benzene, Toluene, P-xylene,Styrene, CS2, Formaldehyde, Acetaldehyde, Phenol, HCl, HF,Hg0, O-, M- and P-Cresol

Meteorological:Wind speed, wind direction, temperature, pressure, humidity andglobal radiation

Others:CO, GC ( PAH), PM10

Parameters Monitored


www.opsis.se

The Opsis open-path stations are using motorized receivers (RE130)to monitor 3 light paths at each station.

The emitters used in this application are of the model EM150,designed for a maximum path length of 2000 m.

The AR520 analysers can handle both UV and IR absorption.

The major sources of Toluene could be identified at ”STS”using Breuer diagram with toluene and wind information


www.opsis.se

Modern technologies such as the open-path DOAS monitoring systemcan provide important information on the pollution situation in andaround industrial estates, such as:

• How residential areas are affected by specific industrial emissions

• Import and export of pollution in the area

• Locations of the most significant sources of pollution

• Concentrations of gases to be compared with guidelines and healthlimits

• A database for future planning and decision-making
