The present invention concerns a powdery slaked lime composition having an Alpine fluidity greater than 50% and including a first fraction of particles having a size less than 32 μm and a second fraction of particles with the size greater than 32 μm, the second fraction being less than 10% by weight, compared to the total weight of the composition. The invention also relates to a method for producing same.

Systems and methods for generating power using hydrogen fuel, such as derived from natural gas, are provided. Feed materials are introduced into a compact hydrogen generator to produce carbon dioxide, hydrogen gas and steam. Sorbent material within the compact hydrogen generator acts to absorb carbon dioxide, forming a used sorbent. Hydrogen gas and steam are separated from the used sorbent and passed to a power generator such as a hydrogen turbine to produce power. The used sorbent is introduced into a calciner and heated to desorb carbon dioxide and form a regenerated sorbent which can be recycled to the compact hydrogen generator.

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.
