    • A process for producing re-hardened water, including: a) an infusion step in which at least CO2 is introduced into water to be re-hardened, to produce a first solution containing free CO2 of a concentration C1; b) a re-hardening step including passing the first solution through a re-hardening material to perform a dissolution process. The dissolution process has a contact time t during which the re-hardening material is dissolved in the first solution and a chemical reaction takes place between the dissolved re-hardening material and a part of the CO2. The CO2 constitutes an aggressive CO2, such that the process produces a second solution of water. The solution contains at least dissolution products, aggressive CO2 of reduced concentration of about C2a, and an equilibrium CO2 of increased concentration of about C2e; c) a separation step including separating from the second solution of a free excess CO2 constituted by aggressive CO2 of concentration C2a and equilibrium CO2 of concentration C2e. The separation step further includes removing free excess CO2 in a gas form, to produce the re-hardened water wherein step (b) is performed so that at least one of the following conditions is met: - C2a C2e and (C2a + C2e)
    • 一种生产再硬化水的方法,包括:a)输注步骤,其中至少CO 2被引入水中以再次硬化,以产生含有浓度为C 1的游离CO 2的第一溶液; b)再硬化步骤,包括使第一溶液通过再硬化材料以进行溶解过程。 溶解过程具有接触时间t,在此期间再硬化材料溶解在第一溶液中,并且在溶解的再硬化材料和一部分CO2之间发生化学反应。 二氧化碳构成了一种侵略性的二氧化碳,使得该过程产生第二种水溶液。 该溶液至少含有溶解产物,约C2a浓度降低的侵蚀性CO2和约C2e浓度升高的平衡CO2; c)分离步骤,包括从第二溶液中分离由浓度为C2a的侵蚀性CO2和浓度为C2e的平衡CO2构成的游离过量CO2。 分离步骤还包括除去气体形式的游离过量CO 2以产生再硬化水,其中进行步骤(b)以使得满足以下条件中的至少一个:-C 2 C 2e和(C 2 a + C 2 e) C1; - C2 0.25C1; - t 15分钟;
