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.

In 2014, the Australian Petroleum Production and Exploration Association (APPEA) published the ‘Method to assist titleholders in estimating appropriate levels of financial assurance for pollution incidents arising from petroleum activities’, referred to as the APPEA Method. The APPEA Method provides a standard approach to quantifying the appropriate level of financial assurance required under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act). The National Offshore Petroleum Safety and Environment Management Authority (NOPSEMA) endorsed the APPEA Method for an initial period of 2 years (until December 2016) with the requirement that APPEA review the method against a broader range of case studies to confirm its validity. In 2017, APPEA applied the APPEA Method to 18 case studies, comparing independently calculated cost estimates with the APPEA Method cost band for each case study. For 17 of the 18 case studies, the independent cost estimate was less than the APPEA Method cost band, confirming the validity of the APPEA Method for those case studies. For one of the case studies involving marine fuel oil, the APPEA Method cost band potentially underestimated the response and clean-up costs. The robustness of the APPEA Method can be improved by amending the hydrocarbon type impact score for fuel oils. Based on the review, NOPSEMA has since endorsed the APPEA Method until September 2018. The APPEA Method is currently endorsed for incidents in which the total volume of hydrocarbon released is <1 000 000 m3 and the total volume of oil ashore is <25 000 m3. Based on an assessment of the response and clean-up costs from three additional case studies that exceeded these limits, amendments to the APPEA Method are proposed that would extend the range of incidents to which it could be applied.

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.
