AMMONIA DETOXIFICATION SYSTEM, FLOATING BODY, AND AMMONIA DETOXIFICATION METHOD

WIPO Patent Application WO/2024/135046

A1

This ammonia detoxification system is provided with: a gas circulation line through which a purge gas comprising ammonia and an inert gas circulates; a dilution tank in which an absorption solution capable of absorbing the ammonia is stored and the purge gas supplied through the gas circulation line can be stored temporarily; a delivery line through which a gas in a gas phase in the dilution tank can be delivered to the outside of the dilution tank; a detoxification device which is connected to the delivery line and detoxifies the ammonia contained in the gas delivered through the delivery line; a flow rate adjustment valve which is provided in the delivery line; and a control device which controls an opening/closing operation of the flow rate adjustment valve. The control device shifts the state of the flow rate adjustment valve from a closed state to an opened state when the ammonia concentration in the gas phase in the dilution tank in which the purge gas is temporarily stored becomes lower than a predetermined value.
