Mine Mouth Coal Gasification into Low Carbon Hydrogen
Keywords:
Coal, Gasification, Hydrogen, Mine Mouth, Steam, Water Gas ShiftAbstract
Coal is fossil fuel which is utilized as fuel to generate electricity via coal-fired power plants (CFPP). There are many government programs that have been planned for the development of CFPP, especially Mine Mouth CFPP’s Program. The aim of this program is to utilize coal directly at the mine mouth. But indonesia's support for the Paris Agreement 2015 has the potential to delay and even cancel the Mine Mouth CFPP’s Program, so that coal mines are planned to be used will be abandoned. Therefore, the government has started to create several coal downstreaming programs so that coal resources in Indonesia can continue to be utilized optimally, one of these programs is through the coal gasification program. Several reactions occur at coal gasification processing; an optimal composition or optimal ratio is required to produce optimal main product and minimize side products. The objective of this paper is to evaluate the optimal ratio steam flow rate for coal gasification simulation. The optimal ratio of steam flow rate to be reacted on Water Gas Shift (WGS) reactor so that optimal products are produced is 0.381 kg steam/kg coal with a CO2 purity level above 90% and H2O isn't squandered a lot.
