AI Technical Summary
How to effectively handle sudden incidents and leaks of excessive ammonia when using ammonia fuel in a large two-stroke single-flow scavenging turbocharged internal combustion engine, so as to avoid ammonia escape and reduce environmental pollution.
A scheme including an ammonia fuel system, an ammonia absorption system, and a scavenging flow path was designed. Excess ammonia is dissolved in water to form ammonia water, which is then used as fuel or a reducing agent to treat ammonia. A cooling loop is used to improve the ammonia recovery rate. A separation drum and an absorption tower are used to separate liquid and gaseous ammonia, and emissions are reduced through an SCR reactor.
It achieves efficient treatment and recovery of excess ammonia, reduces ammonia emissions, improves engine safety and combustion efficiency, and reduces carbon dioxide emissions.
