Abstract

Diesel engine is undoubtably very important in shipping industry. New IMO regulations in 2020 stated that sulphur content in fuel needed to be reduced to 0.5% m/m which is significant considering that the previous limit were at 3.5%. This new regulations aim at the reduction of emission released to the atmosphere which are SOx and PM. In responds MARPOL amandment also stated in annex IV, regulations 14, total sulphur oxides from ships needed to be reduced up to 6.0 gSOx/kW.h or less calculated as the total weight of sulphur dioxide emission This research focuses on using activated carbon to desulfurized marine diesel oil (MDO) which is highly used in the shipping industry to test if it can reduce the sulphur as mentioned by IMO. MDO were desulfurized by using the method of mixing 250 mL of MDO, with three different weight of activated carbon namely, 1 gram, 2 gram, and 3 grams. The mixing were using magnetic stirrer for two hours at 100 RPM. The sample carried out by the experimental method where it is being injected to engine in two variables which are dummy load variable, where the diesel fuel tested at different load given 1000, 2000, 2500, and 3000 at the same speed of 1500 rpm and speed variable, which the diesel fuel tested at different speed which are, 1400, 1500, 1600 at the same load of 2500. Collected data were the SOx emission and Particulate Matter emission and also NOx. It is found that the desulfurized shows the highest SOx detected from desulfurized MDO is 0.146gSOx/kWh. As for the PM emission level the highest emission detected is 0.0031 gPM/kWh. Moreover, the highest NOx detected is 0..903 gNOx/kWh. The data shows there were reduction in emission level.

Mesin diesel tidak diragukan lagi sangat penting dalam industri perkapalan. Regulasi baru IMO tahun 2020 menyebutkan bahwa kandungan sulfur dalam bahan bakar perlu diturunkan menjadi 0,5% m/m yang signifikan mengingat batas sebelumnya adalah 3,5%. Peraturan baru ini bertujuan untuk mengurangi emisi yang dilepaskan ke atmosfer yaitu SOx dan PM. Menanggapi amandemen MARPOL juga dinyatakan dalam lampiran IV, peraturan 14, total sulfur oksida dari kapal perlu dikurangi hingga 6,0 gSOx/kW.h atau kurang dihitung sebagai berat total emisi sulfur dioksida Penelitian ini berfokus pada penggunaan karbon aktif untuk desulfurisasi marine diesel oil (MDO) yang banyak digunakan dalam industri perkapalan untuk menguji apakah dapat mengurangi sulfur seperti yang disebutkan oleh IMO. MDO didesulfurisasi dengan menggunakan metode pencampuran 250 mL MDO, dengan tiga bobot karbon aktif yang berbeda yaitu, 1 gram, 2 gram, dan 3 gram. Pencampuran menggunakan magnetic stirrer selama dua jam dengan kecepatan 100 RPM. Pengambilan sampel dilakukan dengan metode eksperimen dimana diinjeksikan ke mesin dalam dua variabel yaitu variabel dummy load, dimana bahan bakar solar diuji pada beban yang berbeda diberikan 1000, 2000, 2500, dan 3000 pada kecepatan 1500 rpm dan kecepatan yang sama. variabel, dimana solar diuji pada kecepatan yang berbeda yaitu, 1400, 1500, 1600 pada beban yang sama 2500. Data yang dikumpulkan adalah emisi SOx dan emisi Particulate Matter serta NOx. Ditemukan bahwa desulfurisasi menunjukkan SOx tertinggi yang terdeteksi dari MDO desulfurisasi adalah 0,146gSOx/kWh. Sedangkan untuk tingkat emisi PM tertinggi yang terdeteksi adalah 0,0031 gPM/kWh. Selain itu, NOx tertinggi yang terdeteksi adalah 0,903 gNOx/kWh. Data menunjukkan terjadi penurunan tingkat emisi.
