Automated Lube Oil Blending Plant Mounted On High Precision Cells

Weighing Technology - Mounted on High Precision Cells - Automatic Batch Blender - BJVP

Overview:

The AUTOMATIC BATCH BLENDER (ABB) based on weighing technology is most profitable for economic batch sizes of less than 15-25 metric tons and is very easy to use with modern, complex formulations. It consists of a 5 to 20 metric tons blending vessel and an optional 0.5 to 2 metric tons blending/pre-blending vessel. They are mounted on high precision load cells. The blending vessel is equipped with dosing header, heating half pipes, mixer and automatic discharge valve. The system is connected to the dedicated pipelines for base oils and additives. The additives are added from the top of the vessel. Shutoff valves control the flow rate in two stages, decrease the flow rate and finally switch off when set point is reached. The sequence is: The coarse dosing the inlet valve and the header valve will be open 100%. When the fine set point is achieved, the inlet valve will close to e.g. 5% for fine dosing. When the main set point is achieved, the inlet valve will be closed and the header valve is open 100%. The advantage of this dosing is a high-speed procedure. 

Characteristics:
