要約
(EN)
The present invention provides an amount of seawater control device for a scrubber, which is capable of achieving stable operation by supplying a suitable amount of seawater to the scrubber, in such a manner that the sulfur oxide concentration in exhaust gas after processing never exceeds a limit value. An amount of seawater control device for a scrubber, which controls an amount of seawater supplied to a scrubber that purifies sulfur oxide contained in exhaust gas by bringing the sulfur oxide into contact with seawater, includes: a minimum amount of seawater converter (61) which calculates a minimum amount of seawater which is a minimum amount of seawater necessary for an absorption reaction of the sulfur oxide by the seawater, from an engine output and a sulfur content of fuel oil; an amount of seawater correction converter (68) which calculates a corrected amount of seawater which is an amount of seawater at which the sulfur oxide contained in the exhaust gas discharged into atmosphere from the scrubber is equal to or less than a set variable; a summing element (69) which calculates a set amount of seawater by summing the minimum amount of seawater and the corrected amount of seawater; and a pump control device (70) which implements control such that seawater corresponding to the set amount of seawater is supplied to the scrubber.
