Measurement Instrumentation for Caustic Refining and Neutralization
Improve extraction efficiency during caustic refining for edible oil production.
Maintain accurate product quality and consistency
During caustic refining, crude oil is first treated to remove the color, odor, and bitterness. Once complete, the oil is moved to the second phase of refining, commonly known as neutralization. Here the free fatty acids are removed from the crude oil. An alkali solution, usually sodium hydroxide or sodium carbonate, is then mixed with the oil at a temperature of around 104 - 185ºF. This reacts with the free fatty acids to produce soaps. A by-product of caustic refining is a mixture of soap, water and oil known as soap stock. Lastly, the oil is heated in a vacuum dryer to ensure consistent water removal.
High performance measurement solutions are designed to improve process control, optimize product quality, and minimize energy usage throughout the refining process for edible oil production.
