Mass flow measurement - Accuracy not limited by batch size - Simultaneous Meterer Blender - BJVP
Overview:
Simultaneous Metered Blending unit (SMB) combines the high volume production capacity of In Line Blending units (ILB) with operating flexibility of Automatic Batch Blending (ABB). The SMB unit adopts flow measuring technologies of the ABB, but instead of blending in a kettle, the components are sent through a header into designated storage tanks for mixing. The SMB blending unit is the simplest oil blending unit and most appropriate for less automated plants.
SMB is designed to simultaneously measure liquids with a flow meter in correct ratio through a header. The skit mounted SMB unit contains a product feed piping network, optionally separated by family groups (additive-/ baseoil groups) and a piggable mixing pipe.
How it works:
An VP SMB process include three basic steps: (1) Loading raw materials (2) Flushing (3) Pigging
The first step, loading, is transferring the preset matreial into the header line simultaneously. Second, use the rest of basic oil to flush the most residual raw materials from the pipeline to the header line. A pigging system is then typically used to push all liquid in the deader line into the tanks.
