Abstract:

The multi-stage gasification systems represent one of the most promising methods to generate clean energy in future. Because of the worldwide increasing energy demand and the associated CO2 increase this system has to be improved to gain the most out of this process and to decrease its energy consumption. [1] The thermo­chemical process of the multi-stage gasification gives, on closer examination, some possibilities to accomplish energy savings. The pinch analysis is one of the most promising methods to achieve this aim. It is a tool to reduce the energy consumption, to recover heat and to improve operability. Furthermore a better process understanding is created while concentrating on searching possibilities to change the results to better ones. Advantages of the pinch analysis are that it can be applied to nearly every process, to design new plant-concepts and also to re-engineer already existing plants. In addition there are different opportunities within the pinch analysis to reach the set energy targets. [2] The appliance of the pinch analysis allows using the existing heat sources of the gasification process without leaving almost any energy unused either within the process or by transferring it to following processes which are not directly linked to the gasification.
