The conversion of crude oil to useful byproducts can maximize profit, thus adding more value to the refining procedure. One of the processes involved in this conversion is the blending operation. It can be further elaborated as a procedure that involves mixing two or more types of ingredients with special attributes into one mixture. This is done to achieve the desired attributes of all the products in one homogenous batch/final product. This topic will discuss examples of blending, the importance of blending, opposing forces in refining, feasible solutions, etc.
