Due to the constraints of blending devices, only one contaminated oil tank at a station is allowed to blend contaminated oil at a time.
Because blending contaminated oil can increase the benefits of enterprise, the cost of contaminated oil is −1 CNY/m3.
The blending operation means contaminated oil can be blended with the oil in the exporting pipeline according to a certain proportion.
To deal with the issue, three aspects need to be considered: depot operation, oil blending and contaminated batches.
Formula (3) is derived from physical equations, thus it can be used as a standard equation to calculate the blending capacity of contaminated heavy component oil per unit volume mixed with light oil.
In the situation of heavy component oil blended with light contaminated oil, Li et al. (2011) have concluded that flash point is the most sensitive item according to the result of comparing test data with standards' control indexes.
A total mixed ration (TMR) containing a blend of feedstuffs naturally contaminated with Fusarium mycotoxins was fed for 63 d to 12 mid-lactation Holstein cows with an average milk production of 36 kg/d in a completely randomized design with repeated measures including 1) control TMR and 2) contaminated TMR.
In actual production, contaminated oil is usually treated in two ways: blending and fractionation.
The MILP model, considering the constraints of delivery, export, blending, fractionation, maintenance, switching, oil and contaminated oil tank, contaminated oil batch and time node, is solved by MATLAB 2014.
In line with these considerations, a recent study with tomatoes, internally contaminated with S. enterica, showed that a short, but harsh, blending step was more effective than a longer stomaching treatment [ 19].
