Coal gasification of Şırnak asphaltites – coelectricty production by coal bed methane, asphaltite gas and biogas

Abstract

Turkish Energy Agency adopting clean coal to fill the immediate energy gap would also help us set the right example internationally and encourages the meeting of emissions targets globally. Countries such as China, India and the US produce more than 30 times more carbon emissions than the UK and must be encouraged to clean up their coal powered plants. Clean coal technology is the best solution for the short-term if we are to avoid overdependence on imported gas. It can reliably close the Turkish immediate energy gap, within a diverse generation portfolio that secures energy supply. Because coal can be stockpiled, prices remain stable. Indeed, they have remained relatively stable for decades. Clean coal provides the means to achieve the objectives set out in the energy review. The energy review is just the first step. The power plant firms must take serious actions now, or the costs will go up. Gasification plays an important role in providing the power, chemical and refining industries with economically competitive and environmentally conscious technology options to produce electricity, fuels and chemicals. The fluidized gasification process for Sırnak asphaltite uses a vertical kiln type furnace as the heat carrier solid coal ash and flue gas are used. The process can accept shale fines. The oil yield varies, averaging approximately 22-28% on raw coal basis. The oil contains 15-20 % low-boiling fractions. The process produces only small amounts of phenol-contaminated water at low concentrations. Further processing of the water is inexpensive. Most of the phenolic compounds generated in the fluidized process remain in the oil and may be easily removed by water extraction. Gaseous yield is collected out from spent coal in the furnace. Lime and other alkalis were used for desulphurisation of gaseous products and oil fractions.
