A method of and an arrangement for cleaning the exhaust gases of an internal combustion engine (9) used in the power production of a watercraft, especially a large passenger ship, in an exhaust gas scrubber (21) mainly by water. According to the invention, fresh water is produced from seawater in a manner known as such by utilizing the reverse osmosis method, after which the seawater with concentrated salinity produced by the reverse osmosis process is introduced into the exhaust gas scrubber (21) for washing the exhaust gases of the internal combustion engine (9).

Description

METHOD AND ARRANGEMENT FOR CLEANING THE EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE
The invention relates to a method in accordance with the preamble of claim 1 of cleaning the exhaust gases of an internal combustion engine used in the power production of a watercraft, especially a large passenger ship, in an exhaust gas scrubber mainly by water The invention also relates to an arrangement in accordance with the preamble of claim 6
In order to reduce fuel costs, internal combustion engines have been developed so that they may use even fuels of lower quality, for instance heavy fuel oil The problem often involved in these low cost fuels is the impurities they contain, especially sulphur, which as a result of the combustion process generate sulphur oxides, SOx, which also contribute to the acidification of the environment when emitted thereto Attempts have been made to eliminate this disadvantage by introducing the exhaust gases of the internal combustion engine to an exhaust gas scrubber, in which they are washed mainly by water, and by adding, as required, specific additives, for instance sodium hydroxide (NaOH), limestone (CaCO3) or lye (NH4OH) thereto before discharging the exhaust gases to the environment Naturally, these additives need to be carried along with the watercraft, which requires storage, feeding equipment as well as supervision and control of the various contents in the wash water
Alternatively, also seawater may be used as wash water, whereby the concentration of the salts in the wash water is low and seawater is required in large quantities for neutralising the SOx gases in the exhaust gases, depending on the salinity of the seawater in each particular case Even if seawater is free of charge, its low salinity for this purpose increases the need for pumping capacity and related equipment
Seawater needs to be added to the process in multiple quantities compared to the amount of water evaporating into the exhaust gas Consequently, even the rate of flow exiting the process will increase and affect the size of the equipment required for the treatment thereof Only a few SOx scrubbers have been installed on watercrafts. They are dimensioned for seawater or for joint use of seawater and lye The use of lye increases the operating costs and the use of seawater the acquisition price, due to the dimensioning of the equipment On the other hand, there is a substantial need for fresh water on watercrafts, especially on passenger ships. On watercrafts, fresh water is provided either by evaporation or by utilising reverse osmosis. In evaporation the energy demand is fairly high and the salinity of the used seawater will increase only to a minor extent. On the other hand the salinity of the wastewater produced together with the fresh water by using the reverse osmosis method will increase by about 40 %
An object of the invention is to provide a novel method of cleaning the exhaust gases of an internal combustion engine used in the power production of a watercraft, especially a large passenger ship, in an exhaust gas scrubber in order to eliminate the SOx gases therein, by which method the problems related to prior art can be decreased essentially. An object is particularly to provide a method suitable for watercrafts, by means of which the overall economy of the internal combustion engines used on watercrafts, and the treatment of the combustion gases produced by them, can be improved
The objects of the invention are primarily achieved as disclosed in the appended claims 1 and 6, and more closely as explained in the other claims.
The application of the invention is advantageous especially when fresh water is required in large quantities and the production thereof may be provided economically by using the reverse osmosis method This is true especially in the case of large passenger ships and cruisers, which spend also longer times at sea.
The applicability is increased further, if the aim is to reduce the nitrogen oxide emissions, NOx, produced by the combustion process of the watercraft's engines, by utilising clean water.
In the following, the invention is explained by way of example with reference to the appended schematic drawing, the single figure of which illustrates the application of the invention. The drawing shows schematically an internal combustion engine 9, which may be especially a large diesel engine, to which inlet air 14 is conducted and from which exhaust gases 23 are discharged as a result of a combustion process The engine is also provided with a turbocompressor 15
The exhaust gases are conducted to an exhaust gas scrubber 21 , in which they are washed, in order to remove particularly sulphur oxides, SOx, before being discharged to the environment In the drawing only one actual washing cycle is shown, but the washing may, if so required, be performed in one or several stages, and it is carried out at least mainly by using water The wash water flow circulation comprises a wash water tank 19, from which the wash water is pumped by a pump 20 via a feed line 18 to the scrubber The circulation also includes a heat exchanger 22, which may advantageously function by seawater and by means of which the wash water is cooled The cooled wash water condenses in the hot exhaust gas flow and is recovered from the lower part of the scrubber to be reconducted to the wash water tank The wash water tank 19 is provided with a discharge line 17 for discharging excess wash water and washing refuse from the wash water circulation
Clean fresh water is provided by means of the reverse osmosis method by using an apparatus 1 , to which seawater is pumped by a pump 4 via a feed line 5 The apparatus 1 has a fresh water side 2 and a wastewater side 3, from which seawater with highly concentrated salinity is led via a conduit 7 to the wash water tank 19 Possible supplementary water is introduced into the tank via a conduit 16 This supplementary water may naturally be seawater The introduction thereof is controlled according to the waste water volume received from the apparatus 1 so that the salinity of the wash water supplied from the tank 19 to the scrubber will not become too diluted and affect detrimentally the washing result and the demands made thereon
From the fresh water side of the fresh water apparatus 1 water is led via a conduit 6 to fulfil the needs of the watercraft, especially those of the passengers or other similar consumers If the watercraft is provided with means for the reduction of NOx emissions from the internal combustion engines, fresh water may, in addition, be led via a conduit 8 to a tank 10 to be used for this purpose Clean water may further be introduced to the tank 10 from another source via a conduit 12 From the tank 10 the water is pumped by a pump 13 via a filter 11 to be supplied to the inlet air 14 of the engine after the compressor 15 In practise, the supply may preferably be performed in two stages so that additional heating of the flow is provided between the stages from a suitable heat source, for instance by conducting at least a part of the exhaust gases through an exhaust gas heat exchanger arranged in the inlet air passage of the engine The purpose of this additional heating is to get more water evaporated into the inlet air after the compressor 15, whereby also the reduction of NOx emissions in the combustion process of the engine is more efficient
On passenger ships the other consumption, referred to by the conduit 6, is high, and therefore the exhaust gas scrubber 21 utilises much the other fresh water source, referred to by the conduit 12, for humidifying the inlet air after the compressor 15 The invention is also applicable on work ships, where the clean water, referred to by the conduit 8, to be conducted to the humidification of the inlet air of the engine is quantitatively dominating
The invention is not limited to the shown embodiment, but several variations are conceivable within the scope of the appended claims
