Abstract
This disclosure is directed to the use of a portable Surface Enhance Raman Spectroscopy method to detect, quantify, and/or monitor corrosion inhibitors that are present in fluids in a wide range of concentrations in order to manage corrosion treatment in oil and gas production and refining systems or other industrial systems and to reduce the amount of time spent in obtaining data that is reliable and useful for corrosion control.
Claims20
A method for detecting and monitoring a corrosion inhibitor in a fluid, the method comprising:
- preparing a sample of a fluid comprising a corrosion inhibitor;
- exposing the sample to a solution or substrate comprising a metal surface to form an exposed sample;
- placing the exposed sample in a portable Surface Enhanced Raman Spectroscopy (“SERS”) device;
- and
- obtaining data relating to the corrosion inhibitor from the portable SERS device.
