Abstract

The oil-in-water (OiW) contaminants in produced water discharges arising from offshore oil and gasproduction systems are required by global regulatory bodies to be monitored in order to limit theenvironmental impacts of such releases. The level of these contaminants is commonly measured using onlineanalyzers that utilize UV fluorescence to target the luminescent properties of OiW components.

It is known that the nature and variability of the fluorophores in the OiW fractions may influence theresponse of these type of analyzers. In particular these readings can also be affected by chemical residualsused in oil and gas treatment, that may also be present in the produced water. This study reports on the impactof the reaction products of a monoethanolamine based hydrogen sulfide scavenger, used in gas treatmentto remove hydrogen sulfide (H2S), on the fluorescence behavior of OiW discharges, and its implications onthe OiW reporting levels that may be expected from deep-UV and near-UV based analyzers.
