Research On Application

The purpose of this paper is to study the applicability of thermal processed fuel oil (hereafter called waste plastic disposal, or WPD) of diesel engines using low-quality fuel oil. In the experiment, stability of engine operation and components of exhaust gas, such as NOx and COx, were inspected from basic and applicable points of view. This paper illustrates a new test and result of WPD oil applied to marine diesel engines. In recent years, efforts have to be made to develop an advanced technique for recycling waste plastics in order to use scrapped plastics as fuel for diesel engines. It is very important and necessary for us to cope with the increasing calorific value and to satisfy the growing need of environment protection. The experimental fuel oil is obtained by a mixing of diesel oil, WPD, and water.

In these years, a problem of air pollution in a global scale becomes a matter of great concern. In such social situation, diesel engines are strongly required to reduce the NOx and particulate emission in the exhaust gas. In this paper, measurements of particulate emissions from a low speed two-stroke marine diesel engine were conducted with several kinds of diesel oil and a heavy fuel oil, to know the characteristics of particulate emissions at the present situation. The effects of engine load and sulfur content of the fuel on the particulate emission have been examined. The particulate emission from the test engine was measured by partial-flow dilution tunnel system, and particulate matter collected on the filter was divided into four components, SOF (soluble organic fraction), sulfate, bound water and dry soot, by Soxlet extraction and ion chromatograph. Results show that the particulate emission from the test engine operated with heavy fuel oil is three times as much as the value with diesel oil and that not only sulfate but SOF and dry soot concentration increase with the increase in fuel sulfur content. It is also found that the conversion rate from sulfur in fuel into sulfate in particulate matter is nearly independent of the sulfur content in the fuel and increases with the increase in the engine load.

This analysis aims to provide insight and to explore the future usage of methanol as an alternative marine fuel for domestic ships in Indonesia. An overview of potential application, analysis of resources availability, and stakeholder readiness on the topic are provided; related challenges are also identified and further examined. The potential performance of methanol as a fuel is discussed and evaluated via two different perspectives (the ship-owner perspective and the government one) through case studies of two passenger ships owned by the shipping company Pelayaran Indonesia (PELNI): MV. Labobar and MV. Gunung Dempo. As ship-owners tend to look very closely at the economic aspects, a feasibility study is performed by developing a combinatorial scenario approach based on the combination of economic measures of merit (NPV and payback period) along with a technical scenario (main-pilot fuel set-up); the variables included in the calculation are: ship age, ship productivity, and macro-economy conditions. Regarding the government perspective, the main issues are environmental protection and policy compliance. These issues are evaluated by examining six emission types (NOx, SOx, CO2, CH4, N2O, and PM). Additionally, since there is a trade-off situation in government subsidies between the government and ship-owner interests, an optimisation and sensitivity analysis is performed by utilizing a combinatorial scenario model to determine optimum methanol price and external variables influencing the decision to support further use of methanol in the Indonesian market. An important finding was that Indonesia has certain advantages/drives to introduce methanol as a marine fuel. However, methanol competitiveness is mainly dependent on ship productivity and the price difference between methanol and marine diesel oil (MDO). Additionally, policy analysis (through an optimisation approach) could be one of the government options in order to determine the optimum condition in establishing methanol as a marine fuel. Finally, short, medium, and long term recommendations are also provided as the basis for future consideration.

The use of renewable fuels may be an action leading to the reduction of pollutant emissions. This group includes biobutanol as a product of biomass fermentation. Some of its physicochemical properties, including the ability to mix with hydrocarbon fuels, make it suitable for use as a fuel component for marine diesel engines. The article presents the results of research on the concentration of exhaust gas components of a Sulzer 6AL20 / 24 diesel engine powered by a mixture of n-butane and diesel oil. The emission intensity were calculated for the tested components: carbon monoxide, carbon dioxide and nitrogen oxides. The emission intensity surface graphs were created based on the calculated data. The tests were carried out using different concentrations of the mixture of n-butanol and marine fuel.
