METHOD OF DEPOSITION MONITORING

摘要

The invention provides methods and compositions for measuring the formation of scale within a process system. The method involves measuring changes in the cell fouling as reflected on the refraction index measurements of a liquid medium with a refractometer and determining the scale formation from changes in the cell fouling factor. This allows for a refractometer to determine the formation of scale in locations that otherwise would not be measureable.

主权项

1. A method of monitoring the accumulation of scale on a surface in contact with a liquid medium, the method comprising the steps of:
providing a refractometer having an photon emission source, a prism which emitted photons pass through, and an optical sensor constructed and arranged to detect photons that are refracted through the prism, the prism having at least one measuring surface, positioning the measuring surface relative to the medium such that emitted photons will be refracted as a result of the properties of the medium, determining a control critical angle of refraction for the medium for photons emitted by the emission source, emitting photons from the emission source, measuring the cell fouling factor of the measured critical angle of refraction relative to the control critical angle, and calculating the scale formation based on the measured cell fouling factor.
