DIGITAL SOLUTIONS FOR QUALITY CONTROL OF DEMULSIFIERS

Digital technology for quality control of field demulsifiers based on a numerical algorithm for processing digitized Raman spectra (RS) and infrared (IR) spectra was developed and tested. The width of the acceptance limit of the numerical criterion for deciding on the proper quality of demulsifiers for various values of the specific risk of making a false negative decision was calculated. IR and Raman spectra of active substances (Laprols, Neonols, Amines) used for the production of commercial demulsifiers have been registered. Spectral zones and characteristic lines of absorption (IR spectra) and emission (Raman spectra) specific for Laprols, Neonols, Amines have been determined. Using the characteristic spectral bands of the active ingredients, the compositions of demulsifier samples from different batches were compared.
