Method for the determination of the total acid number and naphthenic acid number of petroleum, petroleum cuts and petroleum emulsions of water-in-oil type by mid-infrared spectroscopy |
摘要 |
The present invention relates to a method for the determination of the total acid number and naphthenic acid number of petroleum, petroleum cuts and petroleum emulsions of water-in-oil type by mid-infrared spectroscopy utilising correlation between data gathered by means of absorption spectrums obtained with a Fourier-transform infrared spectrophotometer operating in the mid-infrared band equipped with an attenuated total reflectance (ATR) accessory, and acidity results obtained through reference methods utilising a multivariate regression model. |
