Is there any benefit to in-line blending versus splash blending?
In splash blending the biodiesel is loaded into the tank truck first, followed by the diesel fuel. This allows some mixing to occur. The fuel will continue to mix as the truck moves to the delivery point, providing the roads are a bit rough and the route is long enough. Difficulties in mixing can also be encountered if the biodiesel is loaded on the transport first under very cold temperatures. Under these conditions the two fuels may mix poorly or not at all. There is also a risk of potential fuel spill from overflow. In-line blending uses metered pumps and dual fuel injection system. Blending occurs when the biodiesel is added to a stream of diesel fuel as it travels through a pipe or hose. Mixing is achieved through the turbulent movement through the pipe and when it is loaded into the transport truck. It is the most accurate and reliable system for guaranteeing specific fuel blends and better fuel quality.
