Chemical Industry
Process control and emissions monitoring in a chemical plant is a challenge due to corrosive gases, high dust load, and high temperatures. To use an extractive system in this environment will demand a lot of maintenance.
The OPSIS DOAS system is different and provides chemical plants with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method using an optical measurement path that can operate across the duct.
The optical light is transported in an optical fibre to the analyser and one analyser can operate several paths.
As well as monitoring common gases such as nitric oxide (NO), nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon dioxide (CO2) and water vapour (H2O), systems are available to meet the specific needs of particular users:
- Hydrocarbons (benzene, toluene, xylenes, ethylbenzene, styrene, methylbenzene, methane, etc.) in refineries, petrochemical plants and steel industry.
- Chlorine (Cl2), carbon disulphide (CS2), ozone (O3), chlorine dioxide (ClO2) in textile industries, pulp and paper mills and colour pigment production.
- Hg mercury in power plants, waste incinerators, crematorium, etc.
- Ammonia (NH3) to control DeNOx scrubbers, fertilizer producers, mineral wool, fibre board producers, etc.
- Phenol in mineral wool plants and fibre board production.
- Formaldehyde in mineral wool plants and fibre board production.
- Process (H2S) monitoring in refineries and steel plants.
- HF in aluminium and alumina plants, waste incinerators, fertilizers, refineries, etc.

All Opsis instruments are sold with 1 years parts warranty as STANDARD.
The warranty can, at additional cost, be extended for total peace of mind. Please call to discuss options for this.
Opsis instruments require periodic service and maintenance to both satisfy the requirements of the warranty and to ensure that the highest possible data capture rates are maintained.
Enviro Technology has a large team of in-house and field based service engineers who regularly receive “factory training” and can provide the very best levels of service and support.
Enviro Technology and Opsis recommend that the Opsis DOAS system for Chemical Plants is serviced every 6 months of continuous operation.
A wide range of servicing options are available and can include:
- Pre-scheduled on-site planned maintenance (every 6 months).
- Emergency on-site call-out within agreed timescales (i.e. 48 hours).
- Supply of consumable items (i.e. sample inlet filters).
- Supply of calibration gases and permeation tubes.
- Supply of permeation tube calibrators and zero air generators
- Remote analyser “health-checks” and diagnostics.
- Return-to-base servicing options.
- Local site operation services.
- Data collection and data management services.
Please contact either our sales or customer services teams to request a quotation for on going servicing and maintenance on this analyser.
