For onshore and o� shore use

A micelle is a nanoscale aggregate of corrosion inhibitor that forms when a system has reached saturation i.e. corrosion inhibitor has adhered to every available surface (pipe, solid, interface)

Optimally-dosedCorrosion inhibitor working at its maximum eff ectiveness

Over-dosedSurplus chemical used; increased risk of emulsions and separation issues

Corrosion inhibitor

Micelle Cross-section of micelle

Under-dosedIncreased risk of corrosive attack and loss of integrity

CoMic™ helps to optimise corrosion inhibitor use by measuring for the presence and amount of corrosion inhibitor micelles*. There is a strong link between the optimum functional dose for organic fi lm-forming corrosion inhibitors and the concentration at which micelles form in a system i.e. its critical micelle concentration (CMC).

* Patent pending

Details on use• For onsite use; so avoiding sample

degradation associated with transit time to central lab and subsequent inaccurate results

• Samples are tested (i.e. it is not an online instrument)

• Simple to perform (mix sample and marker, place in instrument, read signal)

• Quick to perform (minutes)

• Data analysis (micelle interpretation) conducted by LUX personnel for robustness

• All chemicals and consumables are provided

Typical data• Fluids from an inter-platform pipeline were tested for the

presence of corrosion inhibitor micelles

• CoMic™ materials were taken to the asset and fresh samples were provided by asset staff

• Testing of samples in the off shore laboratory with CoMic™ only took a few minutes

• Data from testing the ‘input’ fl uid indicated the presence of micelles but these were not apparent in the fl uid reaching the destination platform (‘output’)

• The analysis provided information to the operator, beyond that already available from probes and residual monitoring, to better understand the corrosion risks that existed in the pipeline

Typical CoMic™ data

CoMic™ provides information not off ered by other monitoring approaches; it is a complementary tool

CoMic™ Simple residual analyses e.g. methyl orange

Complex residual analysis e.g. LC-MS

Corrosion rate testing e.g. coupons, probes

“ The CMC should be used as the treatment rate in the fi eld since maximum inhibition is achieved at this concentration.”K. Tsui, J. E. Wong and N. Park,Corrosion 2010 Paper 10326
