Abstract
Acid byproduct from an OAE system is mixed with an aqueous alkaline fluid under conditions that maintain the mixture at or above a target pH level at which the rate of acid neutralization is maximized and the release of CO2 into the atmosphere is prevented. A neutralization controller utilizes sensor data to monitor the mixture's pH level and to control the rate at which acid byproduct is added (e.g., by a dosing pump) to the mixture. A reaction tank and an optional circulation line and in-line mixer are utilized to perform the mixing process. An optional agitator mechanism is provided to stir the mixture in the reaction tank, and to optionally move sensors and/or injectors along circular paths through the mixture. Optional fixed sensors and/or injectors are located in designated spaced-apart regions inside the reaction tank. The mixture is treated using optional flocculation and grit processing systems/devices.
