This project is a study comparing two different thermal conversion paths for Municipal Solid Waste (MSW). The comparison will be focused on technical, economic and emission aspects. One path is the direct incineration of the MSW.
Meanwhile the other consists of submitting the MSW to the process of gasification obtaining syngas which will be used for the production of energy. The thermal conversion is produced in a Combined Heat and Power system (CHP-system) looking at the economic, emission and technical aspects.
CHP incineration plant produces heat and power from mass burning MSW directly without pre-treatment and CHP gasification plant produces heat and power from converting MSW to syngas in a gasifier and then use the syngas to produce heat and electricity.
To get the result of the objective, the following questions have been answered:
* What is the overall economic performance of the two thermal conversion paths?
* What are the differences in emission depending on the path selected?
* What is the overall efficiency?
The results shows that the most profitable thermal conversion path is directly incinerated MSW in the CHP incineration since it is a more mature technology and therefore the costs of applying it are much less than applying the other alternative, however there are other economic cases that is the opposite. In case of pollution, thermal conversion of MSW into syngas for production of heat and power is much more environmental friendly and in case of the overall efficiency is the thermal conversion of MSW into syngas higher.
