All raw material components (base oils and additives) are pumped to the SMB from dedicated tanks, where a series of metering channels equipped with mass flow meter, control valve and non-return valve allow very accurate and simulateneous dosing of all blend recipe componets. The SMB design incorporates a fully piggable distribution header pipe in order to avoid cross-contamination between blend recipes and to maximise product recovery. This unique piggable SMB conecpt even allows for the different family groups of lubricating oils to be blended in the SMB and hence maximises plant equipment utilisation. \n The general principle of operation for the SMB is as follows: Operator provides production dta (such as: product name / code, type, blend size, and tank destination etc) to SMB control system. \n The SMB control system will then automatically dose all required raw material components according to the customers specific blend formulation (recipe), in following three stages: First stage is an initial dosing and transfer of the main blend components base oils and additives, followed by a final dosing and transfer of the remaining base oil. This dosing sequence ensures optimum pigging resultas are achieved, with respect to cross-contamination between subsequent SMB blends.
