Integrated Utilization Technologies of Sea Water Resources

Abstract

In this review, the following five contents were mainly studied for investigating the integrated utilization technology of sea water resources. (1) Re-consideration of the sea water resources. (2) Reappraisal of the production economy of the resources. (3) Trend survey of utilization technology of sea water resources. (4) Proposal of novel integrated utilization process for sea water resources. The novel utilization process is an integrated process which consists of CO₂ capture, desalination, salt production and soda process. This process flow is as follows: The sea water is fed into a reverse osmotic membrane process after sulfate ion is removed. The residual of desalination water is fed to an ion exchange membrane as condensed sea water. The condensed sea water is fed into a salt production process. The salt is fed in to an electrolytic soda process.
