On a lithium adsorption system from seawater system for using drainage from cooling system of thermal power plant

摘要

This study present a conceptual design for a lithium adsorption system from seawater utilizing the drainage from cooling system of thermal power plant. In order to investigate the performance of the proposed system, model tests were carried out using an adsorbent bed set to model the adsorption system. The adsorbent bed set was composed of an outer pipe with a diameter of 52 mm in which an inner seawater injection pipe with a diameter of 18 mm was placed in the middle. The inlet of seawater was located at the bottom of the inner injection pipe, and the adsorbents were accumulated in the space between two pipes. The seawater flows into the the space between the pipes from the inner injection pipe, then passes through the accumulated adsorbent, and finally flows out of the outer pipe. Using the adsorbent bed set, the flow behavior within the adsorbed bed set, the volume rate of expansion, the opermeability of adsorbent, and the amount of adsorption can be analyzed. Based on the data obtained from the experiments, a feasibility study on the proposed adsorption system will be made.
