Abstract: A process and apparatus for electrolyte solution production can be provided so that a modular production can be provided. The modular electrolyte production can be provided so that the production system is mobile for being used in multiple different plants at different geographical locations that are remote from each other. Embodiments can be configured so that electrolyte production is made for a plant specific application that provides an electrolyte solution having a pre-selected concentration of at least one electrolyte for use in at least one electrolyzer of the plant. The production can be mobile so it can be provided at different sites to make the same type of solutions or different solutions specific to the needs of the plants it may support. Some embodiments can utilize an electrolyte material handling device that also modular and mobile. Other embodiments can be configured to utilize an on-site electrolyte material handling device.
