“…Oleh karena itu, dengan berkembangnya dunia maritim yang semakin maju dan bertambahnya jumlah kapal maka akan sangat mempengaruhi tingkat kepadatan alur transportasi laut berserta dengan pencemaran laut yang mungkin terjadi, akibat limbah-limbah yang dibuang dari kapal, terutama limbah yang mengandung minyak [8,9]. Tidak dapat dihindari bahwa setiap kapal pasti menghasilkan air got terutama di kamar mesin.…”

“…Tidak dapat dihindari bahwa setiap kapal pasti menghasilkan air got terutama di kamar mesin. Air got pada akhirnya akan di buang ke laut namun harus diperhatikan agar tidak terjadi pencemaran laut akibat dari pembuangan limbah tersebut [3,6,9,10]. Dan mencegah sanksi yang dapat diberikan pada kapal yang melanggar dimana akan membawa kerugian bagi kapal dan perusahaan pelayaran, maka sekarang ini pada setiap kapal telah dilengkapi dengan peralatan atau mesin yang dapat membersihkan air got dari kandungan minyak Oily Water Separator (OWS) sehingga pada saat di buang ke laut tidak menimbulkan pencemaran [2,9,11].…”

Pada konvensi MARPOL 73/78 Annex 1 untuk kapal tanker berukuran >150 GRT (selain dari kapal tanker berukuran > 400 GRT) dan Marpol Consolidate 2006 Annex 1 Regulation 32 “Oil/Water interface Detector” dan Regulation 34 “Control Of Dischare Of Oil” kamar mesin harus dilengkapi dengan sarana Oily water separator sebagai media pemisah antara air dan minyak. Tujuan artikel ini adalah untuk mengetahui permasalahan sehubungan dengan kendala pengoperasian Oily Water Separator. Metode pengumpulan data pada penulisan artikel ini studi literatur, wawancara, observasi, studipustaka. Hasil dari pemecahan permasalahan perawatan secara rutin perlu dilakukan untuk menjaga kuliatas dari performa mesin Oily Water Separator. Pengoperasian oleh operator kapal harus sesuai dengan standar operating procedure dengan baik dan benar . Selain itu pengecekan fungsi oil discharge monitoring pada sensor oil content meter perludilakukan agar pengaturan oil content meter yang sesuai dengan peraturan dari MARPOL Annex 1 yaitu sebesar15 ppm.

“…However, appropriate selection of the cutter stock also plays an important role. , The characteristics and basic properties of a suitable cutter stock have acquired considerable significance post the implementation of IMO 2020 for reducing the sulfur content to less than 0.5 wt %. The amount of cutter stock needed to reach the required viscosity and sulfur content may be more than 30 wt %. ,, Moreover, the entire mixture must be compatible, i.e., it should not present material separation, which could result in the formation of multiple phases (asphaltene flocculation and precipitation).…”

Comparative Study of Light Cycle Oil and Naphthalene as an Adequate Additive to Improve the Stability of Marine Fuels

et al. 2022

View full text Add to dashboard Cite

Post the enforcement of the Global Sulphur Cap 2020, large amounts of marine fuel have been produced as a mixture of two or more components to achieve a sulfur level of less than 0.5 wt %. This has led to the wider use of diluents or cutter stocks from different origins to comply with the quality requirements of the ISO 8217 standard. These can often be bio- or alternative components with a lower level of stability. This makes it crucial to select components that are compatible and form a homogeneous mixture. The ISO 8217 standard provides commercial and operational protection; however, the stability of the fuel deteriorates over time. Therefore, the purpose of this study was to develop an adequate component or additive to improve the colloidal stability of marine fuels. A set of laboratory-prepared samples was used to verify the positive effects of the addition of a light cycle oil and also a newly developed additive (containing 30 wt % naphthalene as the simple diaromatic hydrocarbon in tetralin). The prepared fuels (with effective additive dosage), when stored for 60 days, maintained the total sediment accelerated (TSA) parameters, confirming the stability of the fuels. The additive converted the unsaleable fuel into fuel that complied with the requirements of ISO 8217. The developed additive can be used for industrial applications in marine fuel production.

“…The most difficult technical challenge is the production of low-sulphur fuel oils (LSFOs) from petroleum feedstock [10]. The existing methods for LSFO production can be divided into two main classes: direct and indirect hydrogenation [11]. Indirect hydrogenation is the cheapest method that does not require large capital investments (e.g., ExxonMobil [12], Shell [13], Sunoco Partners Marketing & Terminals L.P. [14], Mawetal [15]).…”

The effects of asphaltenes from two heavy oil residues on the sedimentation stability of residual marine fuels were assessed and compared. As base components of residual marine fuels, the vacuum residue (VacRes) and visbreaking residue (VisRes) were taken. The heptane-insoluble fractions (HI-fractions), including asphaltenes, isolated from vacuum residue and visbreaking residue, were analyzed to determine the elemental composition (XRF) and cluster parameters (XRD). The results of the analysis of the parameters of the asphaltene cluster (HI-fraction) for vacuum residue and visbreaking residue showed that dγ – 6.1 and 5.9 Å, Lc – 26.72 and 20.78 Å, and La – 7.68 and 7.20 Å. The sedimentation stability of residual marine fuel was determined according to the ISO 10307-1-2009 (TSA) method and described using ternary phase diagrams. The ratio of stable compositions to the total number of possible compositions (with a step of 10 wt%) was 65/66 or 98.5% for residual marine fuel comprising a mixture VacRes/ULSD/LCGO (vacuum residue/ultra-low sulphur diesel/light catalytic gas oil). Meanwhile, the ratio of stable compositions to the total number of possible compositions was 38/66 or 57.6% for residual marine fuel comprising a mixture VisRes/ULSD/LCGO (visbreaking residue/ultra-low sulphur diesel/light catalytic gas oil).
