Research Abstract

Neutralization rate of reaction between hydrogen chloride and sodium including in glass beads was determined under varied conditions of 〜500μ m in particle diameters, 〜0.8 in sodium conversion and 〜0.9 atm in partial pressures of hydrogen chloride by using laboratory scale fixed bed and fluidized bed reactors. The neutralization rate was found to be controlled by diffusion rate of sodium in glass and the diffusivity was 3.3×10^<-16> m^2/s.
A two stage neutralizer was proposed to be consisting of a fixed bed reactor for coarse glass particles and a fluidized bed reactor for fine glass particles. The appropriate processes were designed based on the rate data focusing on the overall energy efficiency including power consumption by glass grinding. In the appropriate processes glass cullet is ground into 100μm in the average diameter then classified sieved. Coarse particles (d>150μm) are used in the fixed bed reactor and fine particles (d<150μm) are used in fluidized bed reactor.
Lab-scale demonstration of fluidized bed neutralizer for fine particles was carried out. In the demonstration experiments a defluidization problem was observed. Adhesive force between glass particles was increased by deposition of sodium chloride on the glass surface. An addition of fine char particles into the glass bed was found to be effective to prevent the defluidization. The addition of fine char particles more than 10wt% of glass bed was found to prevent the defluidization with no mal-effect for the neutralization rate.
Closed flow differential scanning calorimetry (CF-DSC) was developed for direct measurement of neutralization reaction heat of reaction for hydrogen chloride reaction with sodium in glass beads. The neutralization reaction heat was determined as 321 kJ/mol.
Based on the neutralization reaction heat the energy efficiency of the appropriate process was 77.7%
