MONITORING AND CONTROL OF SEA WATER COMPOSITION

Abstract

This report describes the work carried out in the study and preliminary design of a Sea Water Simulator. The purpose of the device is to approximate for various locales and depths, the sea water chemistry represented by eight chemical parameters: salinity, alkalinity, carbon dioxide, pH, oxygen, hydrogen sulfide, phosphate, and Eh. A literature search was conducted to elucidate this chemistry and to obtain data quantitatively interrelating these chemical systems and their physical states. A survey was made to compare the characteristics of commercially available control instrumentation and transducers. Based upon the information gathered, a system was then designed. The envisioned system incorporates computer control of both closed-loop and open-loop chemistries. Predicted accuracies for output composition control are reconciled with suggested USNCEL performance specifications.
