Project summaryThe Project goal: the project is aimed at the decision of relevant questions of brown coal processing from a high-mountainous deposit on the basis of modern technologies of alternative energetics and ash use, with addition of carbon nano-materials for building purposes. Thus risks for ecological infringements decrease as well as the danger of water reduction in glacier-fed rivers of hydrological pool of the KR and CА, the energy safety of the Republic increases leading to the reduction of hydrocarbons import.
The Project task:
In the course of the project implementations of the energetic potential of Central Asia and Kyrgyzstan will be estimated. Possible methods and technologies of power intensity removal, in particular the use of local high-mountainous coal deposits will be suggested, minimal environmental damage and risks (intensive glacier thawing, river drain reduction) will be estimated. Modern developmental technologies of high-mountainous coal deposits (V-shaped (wedge) drilling planes, etc.) will be investigated as well as new effective technologies of alternative power, i.e. firm fuel gasification (brown coal), and obtaining thus qualitative products of combustible gas gasification, semicoke, activated coal (sorbent). Aiming at the reduction of ecological damage to the environment effective ash use will be researched. On the basis of the obtained results the effective modern technologies of brown coal development and processing will be suggested taking into account the increase of energy safety of the country as well as the environmental damage minimization otherwise the existing technologies will be modernized.
The Project relevance is conditioned by the fact that Kyrgyzstan as well as many other countries of the Central Asia has limited potential of hydrocarbons necessary for needs of the Republic and is mainly resolved at the expense of import. However Kyrgyzstan has a great potential for use of alternative energy. Hydroenergetics is the main source of electric power. Thus in 2009 10889,4 million kWt/h of electric power was produced. High and unstable price for hydrocarbons, great dependence of hydroenergetics on yearly weather conditions (lack of water, abnormal severe winter etc.), which in 2007-2008 put the country in the state of emergency forces the search of new effective energy sources. Kyrgyzstan possesses big deposits of brown coal, the known deposits are 3,5 billion tons, and its extraction in 2009 did not exceed 0,4 million tons. Kara-Keche high-mountainous deposit, the largest deposit of brown coal, is located at the height of 3700 metres. One of the serious problems of high-mountainous deposit developing is its closeness to the glaciers which are the main source of river drains in Kyrgyzstan and the countries of CA. Observations show that intensive glaciers thawing takes place, so if in 1960 there were 8208 glaciers then by 2000 only 6445 glaciers remained. Glaciers pollution by firm waste (ash, coal dust etc.) is one of the reasons of this reduction which also leads to intensive glacier thawing. The construction of Kara-Keche hydroelectric power station which is to be a serious source of ecological deterioration is planned. Therefore there exists an acute problem to study mentioned questions as well as to develop the technologies of wasteless processing of brown coal from high-mountainous deposits while using modern technologies of alternative energy.
The participants of the Project together with collaborators suggest carrying out a number of researches in Kyrgyzstan: the development and use of high-mountainous coal-fields, its influence on environmental ecology, the prospects of alternative energy development, and wasteless brown coal processing. To reveal principal causes of its restraint, and then to determine basic trends of wasteless brown coal processing. To create stages, and modern technologies for its processing and to build a experimental model of a coal gasification, combustible gas production, the semicoke, the activated coal (sorbent) and ash processing plant.
The Project is based on fifteen-year experience of training the experts of the department of “Alternative and Renewed Energy Sources» of the Kyrgyz-Russian Slavic University, five years of collaboration with “Ecological movement “BIOM”, long-term work experience with the experts of Open Society “Electrical Stations” agency, the thermal power station in Bishkek, experts in coal industry, St. Petersburg Scientific Technical Center of Applied Nano-technologies as well as long-term work experience with foreign consultants from Russia, St. Petersburg, Germany etc.
The Project category - «Applied technologies» allows effective development of high-mountainous coal deposits as well as use of wasteless technology of brown coal processing instead of classical one (achievement of proper power indicators by direct coal burning). Positive results of researches in the field of brown coal gasification will allow to provide substantial help to Kyrgyzstan, the countries of the Central Asia as well as other countries in a sustainable development, and also preservation of natural resources and ecology. On the main aspect of the project is its coordination with the Kyoto agreement on reduction of harmful emissions into the atmosphere, and other treaties of international organizations in sustainable development and struggle against poverty.
The following fundamental tasks are to be performed during the implementation of the Project:
- To estimate energy potential of the Kyrgyz Republic, to approximate real possibilities of hydroenergetics and coal mining with the forecast for the following years;
- To provide a quality estimation of brown coal high-mountainous deposit processing and to characterize its influence on ecological aspects of the environment (glacier thawing), in particular a river drain of hydrological pool of the KR and Central Asia.
- To define quality characteristics of brown coal in Kara-Keche deposit and to develop effective modern technologies of brown coal gasification;
- To develop and manufacture an experimental model for coal gasification (gazificator);
- To define quality characteristics of the produced combustible gas, semicoke, and activated coal (sorbent), as well as the characteristics of ash received after complete coal gasification;
- To develop the technology of using ash for the production of building materials with the help of modern nano-technologies;
The main results obtained in the course of the project implementation are to be the following:
- To make complex estimation of power resources of the Kyrgyz Republic;
- To suggest measures of effective brown coal high-mountainous deposits processing with minimal risks for the environmental ecology (thawing of glaciers, which are the basic sources for river drains of hydrological pool of Kyrgyzstan and Central Asia.
- To work out effective technologies of wasteless brown coal processing (production of combustible gas, semicoke, activated coal (sorbent), building materials from ash on the basis of nano-technologies);
- To create physical and mathematical model of brown coal burning and management of this process, for obtaining of quality characteristics of the product;
- To create an experimental industrial model for brown coal gasification (gasificator);
- To commercialize and implement the achieved results and industrial model for brown coal gasification into the industry of Kyrgyzstan and other countries of CA, Europe, Russia; to increase energetic safety of the country;
- To increase the ecological safety within the region;
- o exchange information in the course of the Project implementation.
The potential role of the collaborators:
- Exchange of information in the course of the Project implementation.
- Participating in technical testing of the Project activities;
- Holding joint conferences and working seminars;
- Practical application of the Project results and partnership in their commercialization;
- Technical participation in the solution of certain problems of the Project;
- Working out joint technologies of evaluation of the ecological situations within the region.
