(2006) presented a process model in Aspen Plus to estimate biodiesel production costs from soybean oil. In order to analyze the potential economic and environmental benefits of biodiesel production processes, some works use process simulation techniques. In addition to product characteristics, process economics and the associated environmental impact play an important role in successful process designs ( Hill et al., 2006). One of the alternatives is biodiesel, which have shown similar performance to that of conventional petroleum based fuels ( Nigam and Singh, 2008). Over the last few decades there has been intensive research on the development of fuel production processes based on the use of renewable biological materials as feedstock. Petroleum fuels play a vital role in industrial development, transportation, agricultural sector and many others ( Shahid and Jamal, 2008).

It is noted that the requirements for gas turbine fuels used in marine applications are specified in ISO 4261:2013, which is established in 2013. An appropriate guidance on fuel treatment systems for diesel engines is published by the International Council on Combustion Engines (CIMAC). A higher CCAI indicates that the ignition delay will increase in the diesel engine. In the table, CCAI stands for the calculated carbon aromaticity index (a unitless quantity) defined by an equation: CCAIВ = ПЃВ в€’ 140.7log log ( ОјВ +В 0.85)В в€’ 80.6, which is calculated using the fuel density ПЃ at 15вЊ and viscosity Ој at 50вЊ. In the table, for instance, RMA 10 means RMA grade with a kinematic viscosity of 10.00В mm 2/s at 50вЊ. It is noted that RMA is the highest grade and RMK is the lowest one. In the table, the grades of the fuel are shown with abbreviations such as RMA, RMB, RMD, RME, RMG, and RMK. TableВ 2.5.4 shows a list on the standard for other marine fuels or marine residual fuels making based on the ISO 8217:2017. The specifications for fuels in this document can also be applied to fuels used in stationary diesel engines of the same or similar type as those used for marine purposes. The scope of the ISO 8217:2017, which is the sixth edition of the specifications of fuels for marine diesel engines, mentions the requirements for fuels for use in marine diesel engines and boilers, prior to conventional onboard treatment such as settling, centrifuging, and filtration, before use. An international standard of fuels for marine diesel engines is provided and established in 2017 as ISO 8217 by the International Organization for Standardization (ISO). In general, petroleum fuels for marine diesel engines are classified as marine gas oil (MGO), MDO, intermediate fuel oil (IFO), MFO, and heavy fuel oil. Further explanations are presented in A.2 of Appendix. Regulation 18 mentions the requirements which the fuel oil delivered to and used onboard ships for combustion purposes should meet and that the fuel oil should be hydrocarbon blends derived from petroleum refining. In addition, fuel oil quality is regulated by the MARPOL convention Annex VI, Regulation 18. In California, for instance, the California Air Resources Board (CARB) regulation is imposed. In addition, other countries and regions such as the United States, Turkey, and China have their own regional regulations. The values of the limit become more stringent in stages and different outside and inside the ECA as explained in Subsection 2.3.3. As mentioned in Subsection 2.3.3, the sulfur content in fuels is regulated by the MARPOL convention Annex VI, Regulation 14. In view of the advantages of LNG and petroleum fuel, dual-fuel engines have been developed to alternately use LNG and petroleum fuel explained in Chapter 5.ДЇuel regulations for marine diesel engines currently focus mainly on sulfur content in fuels. However, a disadvantage is that a large special tank is needed to store LNG, which creates problems in terms of cost and storage space in a ship. It is said that SO x emission is almost zero, while NO x and CO 2 can be reduced by approximately 80% and 25%, respectively. The advantage of LNG utilization is that SO x, NO x, and CO 2 emissions are greatly reduced. The BOG is natural evaporation gas from LNG in the tank, and it is an inevitable consequence of its storage. In the case of a liquefied natural gas (LNG) tanker, the boil-off gas (BOG) of LNG is used as fuel. In general, high-grade fuels are environment-friendly, but the prices are high. There are different grades of petroleum fuels. Petroleum fuels are mostly used for marine diesel engines.
