Publication number: 20210212345Abstract: Provided herein are methods, systems, and computer-readable media for controlling a deacidification process for an aqueous fluid circulated through a deacidification column. A first pH value, indicative of a pH of the fluid before circulation through the column, is obtained from a first sensor located at an entry of the column. A second pH value, indicative of a pH of the fluid after circulation through the column, is obtained from a second sensor located at an exit of the column. The second pH value is compared to a target pH value for the fluid to determine a pH difference between the second pH value and the target pH value. Based on the first and second pH values, a deacidification capacity of the column is determined. A fluid flow rate of the fluid through the column is adjusted based on the pH difference and the deacidification capacity.Type: ApplicationFiled: May 22, 2019Publication date: July 15, 2021Inventors: Stanislas Baudouin, Eric Reynaud
