Moving down the process flow, the heart of the facility is the blending section. Modern LOBPs generally employ two primary blending methodologies: Batch Blending and Automatic Batch Blending (ABB) or In-Line Blending (ILB). In a conventional batch blending process, base oils and additives are sequentially metered into a large kettle equipped with mechanical agitators or pulse-air mixing systems. For high-volume production, In-Line Blending systems are used. These systems utilize highly accurate mass flow meters and control valves to simultaneously inject base oils and additives into a common header pipe, creating a finished product continuously and reducing the need for massive blending vessels.
