OPAL® Ultimate Online Monitoring Solution for Hydrocarbon in Water

Every platform, refineries, industrial process (…) has to recover as much oil as possible, as efficiently as possible. In order to make improvements you need to understand how the current system is working. SERES Environnement manufactures the OPAL (IMO* certified) allowing real-time measurement of oil concentrations at the inlet and outlet of any separator, providing continuous on-line information about the effectiveness of your separators. The OPAL can also trigger a divert valve to route the produced water through a sand filter. The OPAL – Oil Pollution Alarm belongs to the last generation of online analyser (Nephelometer) for SUSPENDED HYDROCARBON IN WATER enabling reagent free on line, real time, IR scattering measurement.

OPAL® – Efficient Wastewater Discharge Management

Environmental Monitoring

Surface and groundwater

REAL TIME Monitoring stations or mobile laboratories, for the protection of surface water, spring water, rivers and groundwater.
Designed for integration in Water quality monitoring stations (WQMS)

Discharge water

Online monitoring of stormwater and discharge water at industrial sites, wastewater treatment plant. Process water condensates, Thermal exchangers, Industrial and urban wastewater…

Oil and Gas

Oil platforms, refineries and Tank farms generate produced water which requires close management. For every country in Oceania, there are regulations setting limits on the amount of hydrocarbons than can be disposed of overboard and a range of different lab techniques that can be used for reporting this amount. The OPAL and PAUTBAC II from SERES IR based analysers can provide continuous measurement of the oil concentrations in the discharge water from oil and gas processing and storage facilities.

The OPAL not only can provide you with extremely accurate monitoring, but also sense for changes in the size of oil droplets and therefore in process conditions. Using the built in IR detector, the OPAL and PAUTBAC II analysers enable early detection of oil traces in all type of water, ensuring fast overview of the process conditions. As the volume of your discharge water increases, you need a system that will meet your changing demands, work reliably and with minimal operator input required. Having provided hundreds of online monitoring systems worldwide, SERES is the best positioned to assist you along with your water management plan.
