Corrosion Inhibitor containing APQ’s
Quaternary alkyl pyridinium (APQ) salts used in corrosion inhibitors will excite in the UV and emit in the visible range. Wilson’s instrumentation can be used to identify the presence and concentration of these intrinsically fluorescent corrosion inhibitors with a 1 ppm detection limit. The only sample preparation necessary is filtration and dilution. Measurments can be taken out in the field using Wilsons durable QuatBox, in a nearby lab using the Labbox or samples could be studied using the Open Platform System (OPS) that allows for various configurations. Fluorescence in regards to corrosion inhibitor detection provides the high accuracy of HPLC testing and better reproducibility than the chloroform extraction method. For more information refer to Corrosion Inhibitor Residual Measurements.
Corrosion Inhibitors containing Fluorescent Imidazolines
APQ-containing corrosion inhibitors could be quantified using ultraviolet-excitation fluorescence. Engenium Chemicals (Calgary, AB) has recently developed an intrinsically-fluorescent imidazoline corrosion inhibitor, which when formulated into a corrosion inhibitor package provides for fluorescent detection (with UV excitation) with similar detection limits to APQ formulations. Wilson’s instrumentation can thus be used to identify the presence and concentration of these imidazoline-based corrosion inhibitors.
Oil field based Frac Tracers
Fluorescent material such as Frac Tracers can also be excited in the UV to emit in the visible range. Wilson Analytical’s QuatBox, LabBox or Open Platform System (OPS) can be used to identify the presence and concentration of the intrinsically fluorescent Frac Tracer.
Nanochemistry-based fluorescent reagents
Nanoparticles can be used in the oil industry as non-toxic thermally stable reservoir tracers. The fluorescent silica nanoparticles are stable at temperatures up to 250°C, and specifically designed for fracking solutions. Wilson Analytical’s instrumentation can be used to identify the presence of the fluorescent silica nanoparticles with a ppb detection limit. The QuatBox is designed for in field measurements, the LabBox is intended for a nearby lab, and the Open Platform System (OPS) allows for one to perform various tests for research; however all three of Wilson’s instruments provide the ppb detection limit.
