Study on HCl removal for medical waste pyrolysis and combustion using a TG-FTIR analyzer

Hongmei ZHU,Weiying CHEN,Xuguang JIANG,Jianhua YAN,Yong CHI

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 2,   Pages 230-239 doi: 10.1007/s11783-014-0651-3

Abstract: Under both pyrolysis and combustion condition, HCl removal efficiency for medical waste with Ca-basedAdditionally, the difference of HCl removal efficiency for PVC and medical waste was compared.that is to say, HCl removal efficiency of medical waste increased as the increased of Ca/Cl molar ratioFourth, when Ca(OH) was used as additive, HCl removal efficiency for medical waste combustion was aFifth, under the same Ca/Cl molar ratio, HCl removal efficiency for PVC was higher than that for medical

A thermodynamic study of the removal of HCl and H

Joseph LEE, Bo FENG

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 1,   Pages 67-83 doi: 10.1007/s11705-011-1162-4

Abstract: HCl and H S are highly reactive, corrosive, and toxic gases that must be removed to meet stringent environmentalThe thermodynamic behavior of 13 sorbents for the removal of HCl and H S under various conditions includingThe correlation between HCl and H S was also examined.However, the desulfurization capability of some sorbents was greatly affected by the presence of HCl.Particularly, the performance of Cu O was significantly reduced when HCl was present, but the performance
