Sources of Error in oil in Water Measurerments and Their Impact on Comparing Oil in Water Monitors - Case study
1 Introduction The technology for measuring oil in produced water is changing in response to regulatory changes and the need for reducing environmental impacts. Evaluating new measurement technology and methods for measuring oil is complicated by the nature of oil as a parameter. Since, in effect, oil is defined by the method specified to measure it; comparing methods can be a complicated ...

Introduction to Fluorescence for Oil in Water Monitoring
Fluorescence can be found in many applications throughout our day-to-day routines. Commercially, one of the most obvious uses is in fluorescent lighting. For this, fluorescence is used to emit light from a tube without the use of heat, unlike standard incandescent light bulbs that require a heated element. In this example, fluorescence also contributes to energy conservation efforts. At ...

Surfactant-assisted oil-in-water monitoring
A variety of common surfactants have been used to reduce fouling and enhance the performance of fluorescence-based oil-in-water monitors. Among the most effective are the alcohol ethoxylates with HLB values close to 12. Examples are SurfonicTM L24-9 (Hunstman, USA, HLB 13) and TergitolTM 15-S-7 (HLB 12.1). These surfactants readily convert heterogeneous oil/water mixtures into homogeneous, ...

A Guide to Oil in Water Monitoring for Environmental Compliance
Applications for industrial oil in water monitoring can vary greatly. In upstream and midstream oil and gas production applications, monitoring separation efficiencies is key to optimize production rates, preventative maintenance, chemical use, flow, and environmental compliance. Separated water from the oil is called produced water and it must be cleaned of oil before disposal or re-injection. ...

Oil Level Sensors: Monitoring Oil-Water Interface for Separation Efficiency
Overview In the extraction of petroleum (oil) by hydraulic fracturing, oil flows to the well emulsified with fracturing water. As part of the extraction operation, oil and water are separated at the well site. Separation also occurs at the refinery, where crude oil from the well site contains water that must be removed before refining. Separation vessels or separators are used for the process, ...

Monitoring Hydroelectric Dam Sumps - Case study
The Situation Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage: The hydroelectric turbines are lubricated by lubrication oils. The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils. Vehicles including fork lifts, trucks, etc., can ...

Monitoring once through cooling water - Case study
The Situation Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil. These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often use once through cooling water systems. The cooling ...

Understanding Oil-in-Water Instrument Specifications
The measurement capabilities of oil-in-water analysis methods are described by several analytical figures-of-merit. Examples are: Range (Linear and Dynamic) Limit of Detection (LOD) Limit of Quantification (LOQ) Precision (Repeatability and Reproducibility) Sensitivity Accuracy Response Time Some or all of these are often specified by customers in the bid packages issued when selecting a ...

MS1200 Oil in water monitor protects water treatment plant from spill - Case Study
FULL STORY In November 2018,a Multisensor MS1200 was responsible for saving a water treatment plant in the UK from the disastrous conse-quences of a Kerosene spill entering the works. The monitor, installed in October 2014, is lo-cated at an intake from a canal which is used to serve a treatment works a few miles away. The original spillage was from dumpedoil. ...

Solvent-free oil-in-water analysis
Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

Monitoring Leaks from Heat Exchanger - Paper Plant
The Situation A Paper plant in the Eastern US uses 500 GPM filtered pond water for cooling lubricating oil in their paper line. The now warmer water is sewer to an on-site pond. Because the water is used to cool lubricating oil, the plant could not reuse the water in their pulping process for fears of possible oil contamination of the paper pulp. The plant needed to be able to reuse the water ...

Different technology options for monitoring oil in produced water – inline continuous monitoring and IR analysis
No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...
