Because ships burn inferior fuel, the emission of ship exhaust gas has a great impact on environment. In order to effectively deal with increasingly strict limit sulfur content and SO 2 fuel by International Maritime Organization. On basis analyzing characteristics soluble in seawater, this paper studies compares current industrial seawater desulphurization technology other flue desulfurization...

Biological attack of pyrite is a potential method of reducing pyritic sulphur in coal. Integration of such attacks with microwave pretreatment can enhance the efficiency of the process. Alternatively, processes such as oil-agglomeration can be coupled with the biological attack to obtain higher rates of pyritic sulphur removal. In this study desulphurization of Indian (Assam) coal was carried o...

a new solution aiming at coal biodesulphurization has been developed based on the use of bacteria. the most frequently used species of bacteria for removal of inorganic sulphur compounds are thiobacillus ferrooxidans, thiobacillus thiooxidans and thiobacillus acidophilus. in this study the coal sample was decomposed initially and desulphurization experiments was carried out in pure and mixed cu...
