The present invention relates to a continuous process for the production of sodium bicarbonate crystals from the carbon dioxide of a gas stream comprising an absorption step of the carbon dioxide from a gas stream into an aqueous solution comprising a sodium carbonate salt to produce an aqueous solution of sodium bicarbonate, then a crystallization step of the sodium bicarbonate salt obtained at the first step. The invention also relates to a system for the production of sodium bicarbonate crystals from carbon dioxide of a gas stream comprising a control unit 10, an absorption unit 20 and a crystallization unit 30.
