Energy is one of the most important factors for a developing country like Bangladesh. Like the rest of thecountries of the world, the demand for energy is increasing day by day in our country. Energy sector ofBangladesh is exceedingly depended on the limited gas reserve. Given the rising demand for fuel it will bevery difficult t to meat this demand with only indigenous natural gas. About 80% of the power generation inthe country is now gas based. Therefore diversification of fuel has become indispensible it has beenenvision 2021 that 53% of the power generation will be coal based by year 2021. The worldwide scenarioshows that, Coal is the ultimate fuel for future. Bangladesh is very lucky that it has got significant butalmost untapped high quality coal resource. Five coal fields in the country contain 3.3 billion metric tonscoal. Recently rate of coal production from Barapukuria are increased significantly due to application ofmodern coal extracting method, LTCC. Coal to Synthesis gas conversion, is an emerging technology towide the application area of coal and commercially proved technology worldwide. The paper gives anoverview of the current state of coal scenario and natural gas scenario in Bangladesh. Here we discuss theprinciples of coal to syngas conversion technology and aside from a brief introduction to 5 processmethods for conversion of coal to Synthesis Natural Gas (SNG). The Steam-Oxygen Gasification,Hydrogasification, Catalytic Steam Gasification, Underground Steam-Oxygen Gasification, UndergroundHydrogasification processes are discussed with the help of process flow diagram. This paper alsosummaries the present scenario of Syngas production worldwide. Finally we propose a coal based syngasinfrastructure, where coal is converted to syngas, then processed to make Synthesis Natural Gas (SNG),then it transmitted via dedicated pipeline or injected into existing natural gas pipeline to the different typesof user like Household, Thermal Power Plant, Brick Field, Ceramics & Glass Industry and any kind ofthermal process industry. This proposed technology is design to reduce the dependency on natural gas.
