Upgradation of Brown Coal (UBC) - Reducing moisture in raw lignite at site and increasing calorific value will reduce ...
Jun 03, 2008· PT UBC said its technology would also cut the ash content of the upgraded coal by a third, which would make the burning of the fuel more environmentally friendly, while the briqeutted coal …
Oct 15, 2012· Upgraded Brown Coal (UBC) merupakan proses peningkatan nilai kalori batubara kalori rendah melalui penurunan kadar air lembab dalam batubara. Air yang terkandung dalam batubara terdiri dari air bebas (free moisture) dan air lembab (inherent moisture).
Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.
''Upgraded brown coal offers coal-producing countries a way to add value,'' Inubushi said. ''For coal-using countries, UBC will help meet their energy requirements.'' To carry out the UBC project, Kobe Steel has set up partnership agreements with natural resource investment company PT Bumi Resources Tbk and its coal subsidiary PT Arutmin Indonesia.
In the present study, a method was developed to upgrade low-rank coal using palm oil residues. The upgrading process consisted of pulverization, mixing, drying, coating, and briquetting. A palm oil residue (palm fatty acid distillate [PFAD]) was used to upgrade an Indonesian low-rank coal. Pores ...

With the advanced technologies, such as Upgraded Brown Coal (UBC) process, LRC can be used optimally, particularly for the power plant. Suralaya Generation Business Unit (SGBU), which is the largest coal power plant in Indonesia, recently has to use lignite coal or low rank coal because the price of medium and high rank coal is too expensive.
BROWN COAL UPGRADING AND CONVERSION TECHNOLOGY Upgraded Brown Coal (UBC) Technology • Demonstration plant, cap. 1000 ton/day,(kobe steel ltd. Jcoal, PT. Arutmin, and Tekmira), location Satui, South Kalimantan (completted). • The commercial plant, start construction in 2012. Other Upgrading Technologies
UBC (Upgraded Brown Coal) Process at a Glance • Developed by Kobe Steel, Japan and originally subsidized by METI. • Removes moisture completely from lignite by highly energy efficient coal-oil slurry dewatering technology. (Lignite of TM 52% & 2,830 kcal/kg → UBC of TM 0% & 5,900 kcal/kg)
The low temperature oxidation and spontaneous combustion characteristics of dried coal produced from low rank coal using the upgraded brown coal (UBC) process were investigated. To this end, proximate properties, crossing-point temperature (CPT), and isothermal oxidation characteristics of the coal were analyzed.
The UBC Process raises the heat value of brown coal 1.5 times, to the same level as high-rank bituminous coal and has only one-third the ash. At the same time, it solves the problem of shipping and storage limitations, making possible the utilization of upgraded coal as a substitute for high-rank coal.
1999). Among them, UBC (upgraded brown coal) process developed by Kobe Steel Ltd., Japan will be applicable (Deguchi, et. al., 2002). The pro-cess upgrades a LRC and reduces moisture con-tent to be equal to high rank coal. Therefore, it is expected to decrease the susceptibility to spon-taneous combustion. Process condition 0.35 MPa, was milder ...
Salah satu di antaranya adalah teknologi Upgraded Brown Coal (UBC) yang merupakan teknologi peningkatan kualitas (upgrading) batubara peringkat rendah melalui penurunan kadar air total yang dikembangkan oleh Kobe Steel Ltd., Jepang. Keuntungan teknologi ini antara lain karena proses berlangsung pada temperatur dan tekanan rendah.
1 Introduction Utilisation of low rank coals 5 The world's energy consumption is closely correlated with the global economic growth. Extremely rapid economic expansion in many countries outside the OECD, especially in Asia, was the main
strengthening cooperation on coal by introducing more efforts on clean coal technology due to the increasing dependence on coal in ASEAN. Under this MOU, both parties has agreed to target at making a handbook that will support policy makers as well as utility officers and

Prone to spontaneous combustion, brown coal is hardly ever used. On the other hand, because brown coal is noted for its low ash and sulfur, it has the advantage of being environment-friendly when burned. By removing the moisture, Kobe Steel's UBC Process raises the heat value, thereby converting brown coal into a high-grade energy resource.
Lignite (brown coal) is being used only for mine-mouth power generation. The high moisture content in brown coal causes its power-generating efficiency to be considerably lower than that achieved by bituminous coal. Kobe Steel has developed a process for upgrading brown coal by applying a unique slurry dewatering technology.
