<p>Exhaust gas recirculated back to a combustion chamber, e.g. in a closed cycle diesel engine 1, is treated with an aqueous ammonia solution in a unit 9 to remove carbon dioxide. Crystals of ammonium bicarbonate may be removed from ammonia solution circulated from the unit 9 to a tank 5. Metered quantities of liquid or gaseous ammonia from a tank 6 may be added to sea water from the exterior of a vessel wall 23 (Fig. 3) which is supplied to the unit 9.</p> |
