Site selection for installing plasma incinerator reactor using the GIS in Rudsar county, Iran.

Nowadays, the urban waste disposal and the proper location for doing so is considered as one of the most important urban service issues, which has the potential of causing environmental hazards for the citizens, if not done properly. One of the newest methods of waste burial is using plasma incinerator reactors. Using the advanced technology of plasma reactors in waste disposal has been the subject of study for a considerable number of researchers in the last few years. Moreover, insignificant emissions of environmental pollutants and high efficiency in these reactors have led to a high incentive for using them in the area of urban services. Therefore, finding the proper location for the plasma incinerator reactor in order to minimize environmental hazards is considered as a very important issue. In the present study, different parts of this reactor and its working procedure are presented at first. Then, quantitative and qualitative criteria effective on locating plasma incinerator reactor are presented, and these criteria are given proper weights using analytic hierarchy process (AHP) multi-criteria decision making method. Next, the data were collected for the studying area, and then, weighting, analysis, and presentation of geospatial data were performed using the geographic information system (GIS). Finally, the output map for installing location of the plasma incinerator reactor was developed in three classes of good, average, and bad.

A model based on equations of kinetics to study nitrogen dioxide behavior within a plasma discharge reactor.

In this work, a zero-dimensional kinetics model is used to study the temporal behavior of different species such as charged particles, radicals and excited states inside a Dielectric Barrier Discharge plasma reactor. It is shown that, the reactor significantly reduces the concentration of nitrogen monoxide as an environmental pollutant. After a drastic increase, a decrease in the concentration of the NO2 molecules inside the reactor is seen. Nitrogen monoxide molecules with a very low concentration are produced inside the reactor and its quick conversion to other products is proved. The obtained results are compared with the existing experimental and simulation findings, whenever possible.
