Clean Coal Technology (CCT), a joint venture between South African and Chinese expertise, is at the forefront of providing viable and proven environmentally greener coal to liquid technology.
This technology can be applied to Gas to Liquid (GTL), Coal to Liquid (CTL), as well as a new combined fed process (CFTL).The technology offers reduced CO emission, reduced capital and operating costs, as well as simplicity of operation and ease of scalability for stranded, associated and main resource body resources.
This scalability is achieved by a range of sizes in which the technology can be implemented.
The CCT pilot plant – approved for commercial development
The above proven process has culminated in the establishment of a pilot plant in China’s north-west coal-mining province of Shaanxi.The plant is fully operative and has been approved for commercial development by the government of this province.
The approval is based on recommendations and approval by an international panel of experts in the field of Fischer Tröpsch.These include professors of engineering and other leading experts.
At a review meeting to assess the process and the pilot plant, the above panel concluded: “We believe that this technology is innovative and has the potential to put-perform other similar international technologies in terms of emission reduction, economic performance and conversion efficiency.
“This should provide a basis for a more sustainable and competitive technology.We can conclude on the basis of the results and process concepts presented, that this is a world-leading technology that can make a significant contribution.”
The reduced capital and increased operational efficiencies are achieved by designing an innovative process with higher carbon efficiency, resulting in lower COemissions as well as reduced water consumption per ton of product.
The key novelty of this process lies in the one pass design of the system.The elimination of the recycle improves not only the operability of the process, but also does away with the requirement for certain items of equipment that are the key to theoperation of a recycle-based system.The removal of these items reduces the operating costs and as a result has a significant positive impact on the profitability of the process.
In particular, the new design permits the elimination or reduction of upstream large size air separation for gasification, reformers for the recycle of methane from the tail gas, as well as the eradication of the requirement for complex and expensive gas separation for the recycle process.
