table upgrading process which can produce a highly loaded CWM with reduced viscosity. In this study, an upgrading method which has been developed and applied, is an upgraded brown coal (UBC) process. The condition of the process at a temperature of about 140°C and pressure of 0.35 MPa, is much milder compared with other upgra-ding methods ...
Dec 03, 2008· The UBC Process raises the heat value of brown coal 1.5 times, to the same level as high-rank bituminous coal. The process is able to control spontaneous combustion and has the potential to become a clean, outstanding source of energy. Both Indonesia and Japan have high expectations for the early commercialization of the UBC Process.
2. UBC Process Figure 1 shows a schematic diagram of the UBC process. The UBC process developed by Kobe Steel can increase the quality of low-rank coal by means of a slurry dewatering technique at a low temperature and pressure without chemical reactions. Kobe steel started developing this UBC process for Australian brown coal in 1993.
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 .
Upgraded Brown Coal (hereinafter referred to as "UBC®" note)). This process features a dewatering method for efficiently removing the large amount of moisture contained in lignite, thus increasing its calorific value. The UBC process has many applications; this paper focuses on mine-mouth power generation based on UBC powder. 1. Development of ...
Indonesia (Borneo) is an essential producer of coal in the world. Unfortunately, the resulting coal type is mostly in the low-rank, which called brown coal. This study was aimed to evaluate the influence of mixed oil coating to upgrade Borneo brown coal in terms of caloric value and water re-absorption. The additive material used to enhance brown coal is blended oil, such as used cooking oil ...

Coal preparation plant Wikipedia. A coal preparation plant (CPP also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges ...
Nov 01, 2006· Abstract. Upgraded brown coal (UBC) process has been developed to produce a dry upgraded coal which is comparable with a bituminous coal. Differential thermal and thermogravimetry analyses (DTA–TG) have been applied to study the combustion characteristics of some Indonesian raw and upgraded coals produced by the UBC process.
Brown Coal Drying in a Fluidized Bed Applying a Low. This article contains results of an experimental study on the efficiency of the brown coal drying process in a fluidized bed conducted by means of warm air. It also presents results of a study on mathematical modelling of .

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.
This study focuses on the relationship between ash deposition characteristics and ash melting characteristics. Upgraded brown coal (UBC) and two types of bituminous coal with different melting temperatures and ash compositions were used as samples. The deposition tests were conducted using a refractory furnace.
May 23, 2007· 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.
93 TECHNOLOGY REVIEW NO. 29 DEC. 2010 Demonstration of Upgraded Brown Coal (UBC ) Process by 600 tonnes/day Plant Shigeru KINOSHITA ＊1, Dr. Seiichi YAMAMOTO＊1, Tetsuya DEGUCHI, Takuo SHIGEHISA＊2 ＊1 PT UPGRADED BROWN COAL, INDONESIA, ＊2 Technical Development Group Utilization of low rank coal has been limited so far, due
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.
In an effort to upgrade brown coal and produce a transportable fuel, a new upgrading process of brown coal, hydrothermal-mechanical dewatering (HMD), has been developed. The fundamentals of hydrothermal-mechanical dewatering of raw brown coal slurry have been studied over a wide range of process-related parameters. The results from batch tests have shown that the hydrothermal .

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.
Dec 29, 2015· UBC (upgrading brown coal) is a method of improving the quality of coal by using oil as an additive. Through processing in the oil media, not just the calories that increase, but there is also water repellent properties and a decrease in the tendency of spontaneous combustion of coal products produced. The results showed a decrease in the water levels of natural coal bayah reached 69% ...
