Delivery mechanisms and distribution mechanisms are varied, adjusted, or modified based on a desired fuel application. Dimensions, flow rates, pressures, viscosities, temperatures, friction parameters, and combinations thereof may be varied, adjusted or modified. The fuel application may include a scrubber application. The scrubber application uses a delivery mechanism to deliver a wet or dry scrubbing agent at a low pressure to a distribution mechanism. The distribution mechanism distributes the scrubbing agent within the scrubbing chamber. The delivery mechanism is adjustable based on properties of a feedstock utilized to deliver the scrubbing agent, properties of a propellant, or properties of the scrubbing application. The distribution mechanism is adjustable based on desired distribution characteristics including shape, size, or velocity of drops, mists, or particles distributed. Location, processes, and by-products associated with output of the scrubbing application may be based on a stage of the scrubbing application.
