|2. ENERGY AND EXERGY ANALYSIS OF PROCESSES|
Software that can be used in carrying an Energy and Exergy analysis of various processes has been developed and applied in the case of the Plasma Treatment of Sewage Sludge.
Plasma gasification technology has been demonstrated in
recent studies as one of the most effective and environmentally friendly
methods for solid waste treatment and energy utilization. This study focuses
on the thermodynamic analysis of plasma gasification technology, which
includes prediction of the produced synthesis gas, energy and exergy
calculations. To that purpose, an equilibrium plasma gasification model,
called GasifEq, is developed here by using recent thermodynamic data, which
also considers the possibility for soot formation, as a solid carbon
by-product. The GasifEq model also has the capability of energy and exergy
calculations that are required for the optimization of such processes. This
is demonstrated by the presentation of the effect of the most important
process parameters on the energetic performance of the process.
