An experimental investigation is presented of the influences of emulsification of marine fuel oils A and C with water on the micro-explosion phenomenon and combustion characteristics of a burning droplet. The amount of surfactant and water-to-oil ratio by volume in the emulsion are varied to observe the variations of ignition delay, flame length, time required to attain the maximum flame length, duration as well as intensity of micro-explosion, flame appearance, and overall burning time. The measurements show that the emulsification effects on the combustion of marine fuel oils A and C are different. A droplet of C-oil emulsion is shown to be influenced by the addition of water and surfactant more significantly. The micro-explosion phenomena of droplets of A-and C-oil emulsions are seen to occur after and before their ignition, respectively. In addition, separate combinations of water and surfactant content exist for these fuel oils to achieve better emulsification effects on combustion. Droplets of emulsions with W/O = 15/85, E% = 2% for fuel oil A and W/O = 25/75, E% = 1% for fuel oil C are found to have the most violent droplet-disruption phenomenon and the longest flame length.

Negative Environmental Impact

Organosulfur compounds show a negative environmental impact because of SOx emissions by combustion of fuel oils. As a consequence, removal of sulfur is becoming a worldwide challenge. The hydrodesulfurization (HDS) process achieves limited performances in the case of refractory S-containing aromatic compounds, such as thiophene and substituted benzothiophenes (BTs), which require highly energy-demanding conditions (high temperature and pressure conditions). Oxidative desulfurization (ODS) is considered the most promising alternative to HDS. During ODS treatment, the organosulfur compounds are oxidized to corresponding sulfoxides and sulfones, which can be successively removed by extraction with polar solvents. Different stoichiometric oxidants have been used in the ODS processes with a different degree of efficacy and environmental impact. The design and development of catalytic procedures can increase the ODS energy efficiency as well as make it more economical and environmentally acceptable. Here we describe the advances in nanostructured organometallic catalysis and biotechology applied to ODS treatment.

To reduce the number of germic or nosocomial infections, especially come from waste disposal. Especially for hospitals, the disposal procedure should cut off the chain of transmission or the spread of disease which are came from the clinical waste or medical waste by burning the clinical waste or medical waste using the incinerator. Incenerator is used with high temperature by 800 ° C. Incenerator has been proven to reduce medical waste about 70% to 90%, but it can also reduce the number of pathogenic bacteria to zero in percentage. In the using of incinerators, there has not been an assessment of the effectiveness of incinerator usage until today. Research method which has been used is analytical research to determine the effectiveness of incinerator usage due to the destruction of the medical waste. The result of examination about effectivity of incinerator usage for 4 times of combustion was obtained that the burning volume of medical waste exceeding the required incenerator volume of 0.7 m3/day is very ineffective with the burning time for 2 hours, because of the results of the research with different volume shows that the volume of 0.7 m3 is an effective volume for incinerators in Public Hospital of ABC City, this is being streghtened based on the results of hypothesis testing that shows the volume of 0.7 m3 would be more effective volume and could give a significant result. In fact, the medical waste should be burnt twice a day in order to be able to burn all the medical waste which is generated.
