5.2023173396METHOD FOR SUPPRESSING MARINE ACIDIFICATION

JP - 07.12.2023

Int.Class B01D 61/00 Appl.No 2022085626 Applicant SUMITOMO HEAVY IND LTD Inventor HIRATA KAZUHIRO

PROBLEM TO BE SOLVED: To provide a method for suppressing marine acidification that enables safe and stable treatment of carbonate and improves marine environment.

SOLUTION: A method for suppressing ocean acidification includes: an injection step in which carbonate is introduced into ocean, and a step of determining a location for retention by which the location for retaining carbonate is determined based on ocean acidity, wherein carbonate is retained at the location determined in the step of determining the location for retaining carbonate. According to this invention, when injecting carbonate into ocean, a location for retaining carbonate is determined based on ocean acidity, and carbonate is supplied (transported) to and retained in that location, effectively promoting the alkaline pump effect. This enables safe and stable treatment (dissolution) of carbonate, and neutralization of seawater in areas of high ocean acidity (suppression of ocean acidification), as well as improvement of the ocean environment by increasing the efficiency of carbon dioxide absorption.
