History of the White Coal Technology
An upgrading process for sub-bituminous coal based on a relatively simple thermal drying process followed by physical and chemical stabilization through a novel binderless briquetting process has proven to be economically attractive while at the same time providing an upgraded shippable product that can be handled and stored safely. The process is known as Binderless Coal Briquetting (BCB), or alternatively, the White Coal Technology.
The White Coal Technology process has developed from the work of KR Komarek in the late 1950’s, one of the worlds leading manufacturers of briquetting equipment. This work was picked up by TraDet Inc. (USA), a world authority on coal thermal drying and CSIRO (Australia). CSIRO started the development of the White Coal Technology in 1993 and, through seeking expertise in dryer and briquetting technologies, formed a group that would work together to develop the White Coal Technology. The development progressed through laboratory scale work at CSIRO and initial pilot scale work in the USA, through a 0.2 tonne per hour pilot plant at CSIRO, a 3 tonne per hour development plant in USA and finally a 10 tonne per hour development plant in Collie, Western Australia built by Griffin Coal (Australia).
Binderless Coal Briquetting Company Pty Ltd (BCBC) acquired the exclusive global rights to the underlying technology on 27th April 2005. BCBC is a subsidiary of White Energy Technology Limited which in turn is a fully owned subsidiary of White Energy Company Limited. Since acquiring the White Coal Technology, White Energy developed it further and has demonstrated its ability to raise capital successfully on the public market. White Energy will continue to commercialize this technology. It will conduct further research and development around plant scale up and design and through its White Coal Technology Demonstration Plant, work with different types of coals to demonstrate to potential customers the end product result and costings.
