Removal of dissolved matter from liquids is a problem of considerable difficulty in some cases. For instance, purifying brackish water for domestic or industrial use is a chronic problem in some coastal and/or arid regions. Also, dozens of municipal water sources contain large amounts of dissolved matter which must be removed before the water can be used. In order to achieve high levels of separation, many methods in which the fluid passes back and forth through a bed of absorbents have been examined over the years. The present proposal seeks to study a method, known as dual recycle thermal swing absorption (DRTSA) process, in which the product from the equipment is recycled back to increase the extent of separation substantially. The objective is to examine some fundamental physical and chemical issues that affect the performance of this process so that the economics of the process can be evaluated subsequently. If successful, this work will be of value in many industrial and domestic treatment processes.

从液体中去除溶解的物质是一个问题， 在某些情况下相当困难。 例如，净化 用于家庭或工业用途的微咸水是一种慢性疾病， 一些沿海和/或干旱地区的问题。 此外， 城市水源含有大量的溶解物质 在使用水之前必须将其除去。 为了 实现高水平的分离，许多方法，其中 流体通过吸收剂床来回流动， 检查了多年。 本建议旨在研究 双循环变温吸收法（DRTSA） 过程，其中从设备中回收的产品 以显著增加分离的程度。 的 目的是检查一些基本的物理和化学 影响该过程性能的问题， 随后可以评价该方法的经济性。 如果 如果成功，这项工作将在许多工业和 国内处理工艺。
