Abstract

Mesin diesel kapal merupakan sebuah mesin yangterbukti handal dari segi fungsi dan efisien dalampenggunaan bahan bakar.Namun salah satu kekurangan dari mesindiesel adalah terdapat emisi pada gas buang yang berupa SOx, NOx, dan CO. Dapat membahayakan kesehatan dan merusak kualitas udara serta hujan asam (HNO3 danH2SO4) yangdapat mengakibatkan kanker. Gas CO yang dapatmenyebabkan kematian apabila terhirup secara langsungmenyebabkan bertambahnya suhu bumi akibat pertambahan CO2 atau global warming.Buruknya kondisi kualitas udara akibat gas buang yang dikeluarkan mesin diesel kapalmengakibatkan International Maritime Organization(IMO) mengatur standar minimum emisi NOx dan SOx dalamANNEXVI.Untuk mengatasi emisi udara yang dihasilkan dari diesel engine salah satunya menggunakan sistem SCR (Selective Catalytic Reduction).Sistem SCR yang konvensional menggunakan bahan urea dan amonia sebagai bahan injektornya.Namun, bahan urea dan amonia ini masuk dalam batasan aturan MARPOL ANNEX II.Oleh karena itu, ada bahan hidrokarbon yang dapat digunakan sebagai bahanX injektor dari sistem SCR. Hidrokarbon sendiri didapatkan dari bahan bakar dari kapal yaitu solar. Dalam skripsi ini akan dilakukan dengan pengujian beberapa variasi zeolite yaitu 60% zeolite, 45% zeolite, 30% zeolite, dan 15% zeolite. Sedangkan variasi beban terdapat 1700 watt, 2600 watt, dan 3500 watt. Dan variasi injeksi yaitu amonia dan hidrokarbon. Dalam pengujian mesin Yanmar TF 85 MH-di untuk mengurangi NOx lebih efektif meggunakan injeksi hidrokarbon daripada amonia. Karena hidrokarbon dapat mengurangi emisi NOx sebesar 21%, sedangkan amonia hanya 12%. Sehingga jika diaplikasikan ke dalam kapal tidak perlu menambah tangki untuk amonia karena solar (hidrokarbon) sudah termasuk didalam tangki bahan bakar di kapal ====================================================================================================== Diesel engine is a machine that has proved reliable in terms of function and efficient in fuel use. However, one drawback of diesel engine emissions is contained in the flue gas in the form of SOx, NOx, and CO. It can be endangering for the health and impairing the air quality that will create acid rain (HNO3 and H2SO4) which can lead to cancer. CO gas that can cause death if inhaled directly cause an increase in the earth's temperature due to the increase of CO2 or global warming. The poor air quality due to exhaust gases released ship diesel engines resulted in the International Maritime Organization (IMO) has been set into minimum standards for NOx and SOx emissions in ANNEX VI. To overcome the air emissions generated from the diesel engine one of which uses the SCR system (Selective Catalytic Reduction). Conventional SCR system which uses materials urea and ammonia as material injector. However, urea and ammonia these materials fall under the restrictions of rules MARPOL ANNEX II. Therefore, there is a hydrocarbon material thatXII can be used as an injector of the SCR system. Hydrocarbons itself obtained from the fuel from the ship that is solar. In this thesis will be carried out by testing several variations of zeolite is 60% zeolite, 45% zeolite, 30% zeolite and 15% zeolite. While the load variation of more than 1,700 watts, 2600 watts and 3500 watts in variations of ammonia and hydrocarbon injection. In testing engine Yanmar TF 85 MHin to reduce NOx more effectively use hydrocarbon injection rather than ammonia. Because hydrocarbons can reduce NOx emissions by 21%, while only 12% ammonia. So that when applied to the vessel does not need to add to the ammonia tank for diesel fuel (hydrocarbon) is included in the fuel tank on board
