Industrial sectors that work with large numbers of machines will need to store, transport and dispose of large amounts of waste oil, which increases with every oil change. Disposal of this waste oil is associated with significant cost. As an alternative, waste oil can be converted into a valuable resource using GEA’s centrifuges. The treated oil can be used as a high calorific value.

Fine coal and high difficult washing coal are major causes of poor recovery of combustibles, excessive moisture and high waste disposal costs in coal beneficiation processes. The oil agglomeration process is an excellent method for cleaning and recovering coal fines below microns, difficult washing coals and middlings particularly of very high ash content.

INTRODUCTION 9Indian coals, in general are inferior in quality and difficult in cleaning characteristics. 9Due to ‘Drift Origin’, the coals contain inherent mineral matter or contaminates. 9The Erstwhile CFRI ever since its inception in has been campaigning for establishment of large Coal Preparation plants to upgrade inferior coking coals for steel making.

The practice of cofiring biomass in full-scale coal utility plants is increasing, due to the benefits of reduced fossil fuel based CO2 emissions.

Biomass also tends to have a lower sulphur content than coal and therefore emissions of SO2 can be reduced. The same is true for NOx emissions from lower fuel nitrogen content. Further.Following Biofiltration, the treated effluents are discharged to the sea.

A certain amount of treated effluent is stored in a tank, to be used for washout and cleaning of the Biofilters (with compressed air). The Biofilters’ washout water is stored in a separate storage basin, and is .FOR Government of India Final Draft Prepared for Ministry of Environment and Forests TECHNICAL EIA GUIDANCE MANUAL FOR COMMON EFFLUENT TREATMENT PLANTS.
