Coal Transportation Technology with Pipeline System: a Step Towards National Energy Independence

The increasing use of coal as a source of energy instead of petroleum, it will also increase the ability to produce coal, as well as the national energy policy (KEN) in 2009 in which the use of coal in the energy mix in Indonesia in 2025 rose as much as 33 %. Plus more of the coal transport that causes the social impact like a jam. Therefore one of the prospects of coal transportation system to be developed is a pipeline system, which is a system of coal transportation by utilizing pipelines for transportation, while the material is transported in the form of liquid or slurry that assisted with the pump. Coal srurry pipeline activities include grinding, mixing ratio of 1: 1 or concentration of crushed coal by 60 % and slurrry transport via pipeline. In the end, the coal is separated from the water and ready to be used to fuel power plants. In Indonesia, the pipeline transportation system for transporting coal has never been done, therefore it is necessary for the study and analysis of the possibility of using coal transportation pipeline system.
