A system and method are provided for in-line processes of blending butane into gasoline streams, and for blending butane into a gasoline stream at any point along a petroleum pipeline. The invention additionally provides a method for measuring the vapor pressure and vapor to liquid ratio of the gasoline, both upstream and downstream of the blending operation, as well as the sulfur content of the butane entering the blending operation. The blending operation can be controlled to ensure that the blended gasoline meets EPA requirements for vapor pressure and sulfur content of gasoline. The invention further provides a method for accessing and monitoring the operation off-site.

Computer systems and non-transitory computer readable media for determining an amount of an ingredient for a preparation for a requested therapy (e.g., an order or a prescription) includes an identifier, volume, and amounts of first and second compounds in each of a plurality of premix solutions. A predefined formulary comprising a formulary concentration of each of a plurality of additions is provided. A premix solution is selected. An amount of a first additions to be added to the premix solution may be selected. A number of bags of the premix solution, needed to satisfy a volume associated with the selected premix solution, are optionally reserved. An additive volume is determined at least by the specified first amounts of the first addition and a corresponding formulary concentration.

A flow control device is disclosed. The flow control device includes a solenoid, the solenoid including an armature. Also, a piston connected to the armature. The piston includes a primary orifice. The piston having an open position and a closed position. A piston spring connected to the piston is also includes and at least one secondary orifice. The movement of the piston to the open position at least partially opens the at least one secondary orifice and the movement of the piston to the closed position at least partially closes the at least one secondary orifice. The movement of the armature actuates the piston movement and controls fluid flow from the primary orifice through the at least one secondary orifice.
