Use of detection techniques for contaminant and corrosion control in industrial processes

A method for monitoring at least one industrial fluid comprising:

• a. performing a separation technique on a sample of the at least one industrial fluid to form a separated sample;
• wherein the separation technique is selected from the group consisting of ion chromatography (IC), high performance liquid chromatography (HPLC), capillary electrochromatography (CEC), electrokinetic chromatography (EKC), affinity capillary electrophoresis (ACE), non-aqueous capillary electrophoresis (NACE), capillary electrophoresis (CE), capillary zone electrophoresis (CZE), gradient elution moving boundary electrophoresis (GEMBE), capillary isotachophoresis (CITP), capillary isoelectric focusing (CIEF), and combinations thereof;
• b. introducing the separated sample into a device employing a detection technique selected from the group consisting of surface enhanced Raman scattering (SERS), nuclear magnetic resonance (NMR), indirect UV spectroscopy, contactless conductivity, and combinations thereof;
• and wherein the industrial fluid is selected from the group consisting of a refinery fluid, a production fluid, cooling water, process water, drilling fluids, completion fluids, production fluids, crude oil, feed streams to desalting units, outflow from desalting units, refinery heat transfer fluids, gas scrubber fluids, refinery unit feed streams, refinery intermediate streams, finished product streams, and combinations thereof;
• c. detecting at least one composition within the sample, wherein the at least one composition is monoethanolamine (MEA) in the presence of other compounds;
• and
• wherein the method occurs in an amount of time less than about 24 hours.
