An Environmental Application in Acid Gas Cracking With a High-Frequency Pulsed Gliding Arc

Abstract

An environmental application of a high-frequency pulsed gliding arc (HFPGA) is presented in this paper. It consists of the degradation of an acid gas mixture (CO2 and H2S) considered as a residue during its sweetening process and contained in sour gas. Plasma interaction with acid gas, leads to a molecular dissociation, mainly forming CO and H2, also known as syngas. In recent years, the syngas has become one of the alternative energy sources more profitable and investigated. The mixture of carbon monoxide and hydrogen, recovered from the decomposition of organic material, provides energy power with innovative applications in microturbines and fuel cells, in conjunction with others applications. The molecular dissociation is achieved with a HFPGA, which, among other properties, has the possibility of working as cold plasma and thermal plasma. Electric analysis was performed to determine instantaneous current, voltage, and power used in the HFPGA for acid gas treatment. From analysis of power consumption, the SE and ECE were 17.62 kJmol-1 and 59.05%, respectively. The analysis of solid residues obtained during the treatment with HFPGA is also presented.
