The use of energy in the world is steadily increasing. The greatest rate of increase is taking place in centrally planned economies and less developed countries. Reserves of coal are widely distributed and are several times those of oil and gas; thus coal can contribute to energy needs for many years to come. New technology can much reduce the environmental effects of coal use such as smoke, dust and acid gases. High efficiency techniques of power generation can reduce the production of Sulphur Dioxide per unit of electricity generated.
Damage to lakes, forests and artificial objects results from combinations of many factors, some of which are related to fossil fuel, others not. Existing legislation to reduce acid emissions may be only partially effective if solutions to the other problems are not found. The use of coal may have effects to the climate via the greenhouse effect. Although this concern is not yet proved, there is an agreement, that it is sensefull, to encourage technologies, which could help to reduce Sulphur Dioxide emissions and in particular could promote energy conservation and efficiency on a global scale.
To find a solution in respect to reduce the pollution of the environment, it is vital to start at all points, where pollution takes place, and all influences have to be taken into account. One of those programms to protect and rehabilitate the environment is the EUROPEAN COMMISSION ENVIRONMENT PROGRAMM named SIMDES.
SIMDES was created to investigate a chemical process for low temperature desulphurisation of exhaust gas. The aim of this project is to improve the efficiency of the low temperature desulphurisation process, control and machinery in order to further reduce Sulphur Dioxide concentration in exhaust gas. As a result of the work of SIMDES it is expected to increase the amount of desulphurisation at plants and to reduce the amount of the sorbent material which is being used at the moment. The advantage of this new method means, that much smaller plants will be able to afford to implement this process.
