Soapstock and spent bleaching earth (SBE) are two significant waste byproducts of the animal and vegetable oil refining industries, particularly the fish processing industry.

Traditionally, the oil content of soapstock and SBE is determined using acetone and hexane extraction, respectively. Both approaches necessitate laboratory setups and the use of dangerous chemicals and are generally time-consuming.
On the other hand, Fourier transform near-infrared spectroscopy (FT-NIR) is a dependable and non-destructive approach for determining the concentration of soapstock and SBE in oil refining processes.
This feasibility study, based on ABB's FT-NIR solids analyzer, highlights the advantages of this method. It provides results in less than 2 minutes per sample. It eliminates the need for chemical solvents or reagents and features a user-friendly interface that allows operators without chemistry experience to conduct measurements easily.
