Liquid blending process occurs in the hydraulic blender. This process involves supplying of all components simultaneously according to the recipe. Finished product is delivered to storage tanks. The advantages of such blending technology are easy and accurate component dosage control, substantial reduction of fuel blending process time, no need of batching tanks for finished product homogenization. In the course of the fuel blending process in the stream mixer the consumption of each component is continuously controlled to provide finished product with steady quality parameters, according to the blending recipe. The fuel blend, obtained from the stream mixer, is homogenic and its component composition is in exact match with the recipe.
