As part of the expansion of a new chemical manufacturing facility, the debottlenecking of an existing brine system for an increase in soft water demand and the usefulness of the method was studied. Mathematical equations were used to estimate the salt loading profile. The effect of increasing soft water demand on the brine system was studied using parameters such as the amount of salt, the number of refills of brine tank, the brine pump run time, the number of days for the salt pit to empty, and the number of brine truck deliveries. The generalized mathematical equations derived and presented in this study can be used for any debottlenecking studies. The study showed that the existing brine pit and brine pumps can be reused for the future brine demand. The study showed with a good truck delivery logistics and a robust pit maintenance program, the number of regenerations can be increased while utilizing the existing brine pit system. The risk level remained the same as in existing pit systems since an increase in the frequency of pit maintenance was used to account for higher brine levels in the pit. The study methodology can be utilized for similar brine and softener systems in plant expansion operations to avoid a new pit system and to reduce capital costs. Brine seepage through the new concrete walls was avoided effectively. A polyvinyl chloride above ground tank system is recommended for brine service in all future projects where feasible.

评估现有盐水系统的容量并估计增加软水需求的盐负荷分布，以避免土壤污染

作为新化学品制造设施扩建的一部分，研究了现有盐水系统的瓶颈以增加软水需求和该方法的实用性。数学方程用于估计盐负荷曲线。使用盐量、盐水罐的再填充次数、盐水泵运行时间、盐坑排空的天数和数量等参数来研究增加软水需求对盐水系统的影响。盐水卡车交付。本研究中导出和呈现的广义数学方程可用于任何消除瓶颈的研究。研究表明，现有的盐水坑和盐水泵可以重复使用，以满足未来的盐水需求。研究表明，凭借良好的卡车运输物流和强大的维修站维护计划，在利用现有的盐水坑系统的同时，可以增加再生次数。风险水平与现有矿坑系统保持相同，因为矿坑维护频率的增加被用来解决矿坑中较高的盐水水平。该研究方法可用于工厂扩建操作中类似的盐水和软化器系统，以避免新坑系统并降低资本成本。有效地避免了盐水通过新混凝土墙的渗漏。在可行的情况下，建议在未来的所有项目中使用聚氯乙烯地上储罐系统用于盐水服务。风险水平与现有矿坑系统保持相同，因为矿坑维护频率的增加被用来解决矿坑中较高的盐水水平。该研究方法可用于工厂扩建操作中类似的盐水和软化器系统，以避免新坑系统并降低资本成本。有效地避免了盐水通过新混凝土墙的渗漏。在可行的情况下，建议在未来的所有项目中使用聚氯乙烯地上储罐系统用于盐水服务。风险水平与现有矿坑系统保持相同，因为矿坑维护频率的增加被用来解决矿坑中较高的盐水水平。该研究方法可用于工厂扩建操作中类似的盐水和软化器系统，以避免新坑系统并降低资本成本。有效地避免了盐水通过新混凝土墙的渗漏。在可行的情况下，建议在未来的所有项目中使用聚氯乙烯地上储罐系统用于盐水服务。
