Efficiency Evaluation of RDF Plasma Gasification Process

Single-stage plasma gasification of RDF

Experiments with refuse-derived fuel (RDF) were performed on a single-stage plasma gasification reactor system. The performance of the process in converting the feedstock to syngas is assessed for different oxidizing agents (H2O, CO2 + H2O and CO2 + O2). The experimental results show that syngas composition varies significantly with gasifying agent(s), while carbon conversion efficiencies vary ...

Plasma gasification of sewage sludge: Process development and energy optimization

The plasma gasification process has been demonstrated in many of the most recent studies as one of the most effective and environmentally friendly methods for solid waste treatment and energy utilization. This method is applied here to the treatment of sewage sludge. Results are presented for a case study concerning the Athens’ Central Wastewater Treatment Plant, at Psittalia Island. An integra...

A thermodynamic analysis of solid waste gasification in the Plasma Gasification Melting process

Plasma Gasification Melting is a promising technology for solid waste treatment. In this work, a thermodynamic analysis has been conducted to evaluate the advantages and limitations of the PGM technology. According to the characteristics of the PGM, the whole process was divided into four sections such as drying, pyrolysis, char gasification and inorganics melting. The energy and exergy in each...
