“…However, it should be noted that the particle sizes of these primary HCl p particles might further increase to the accumulation mode because of the effects caused by both the Brownian and turbulent coagulation (Friedlander, 2000). In addition, our results were also consistent with the results obtained by Schenkel and Schaber (1995).…”

This study was set out to investigate the emission characteristics of HCl (in both particle (HCl p ) and gaseous (HCl g ) forms), and Cl 2 during the trichlorosilane (TCS) burning process under various relative humidity conditions (RH; range = 55%-90%) which might exist at its storage area. All experiments were conducted in a test chamber. We found that , emitted from the TCS burning process for the all selected RH conditions. The particle sizes of HCl p fell to the range of the accumulation mode (MMADs = 0.808-1.04 μm; GSDs = 2.13-3.50). Fractions of emitted HCl p reaching to the alveolar region (= 85.8-88.8%) were much higher than that of the tracheobronchial region (= 6.53-8.80%) and head region (= 4.67-5.40%). It is concluded that more ill-health effects on the deep lung region can be expected than other regions as workers exposed to the contaminants emitted from TCS burning processes.

“…If particle diameters of more than 1 µm should be reached, the maximum values of the curves at saturation ratios S > 1 must be exceeded. Similar results were obtained for sulfuric acid and hydrochloric acid droplets , . Consequently, for an appreciable enlargement of insoluble as well as for soluble particles up to diameters of d > 2 µm, at least a slight supersaturation of the surrounding gas phase is always necessary.…”

Enlargement of Submicron Gas‐Borne Particles by Heterogeneous Condensation for Energy‐Efficient Aerosol Separation

et al. 2019

To improve the efficiency of aerosol separation, a process sequence for particle enlargement by condensation of water vapor on their surface is suggested. The presented method makes use of packed columns in non‐equilibrium operation to achieve supersaturation, which is required for droplet growth. Although this method is known for several years, it is not widely used in industrial processes and still needs accurate investigations for consolidation and establishment. The simulation tool AerCoDe3.0 for predicting saturation and particle growth in packed columns allows investigating the thermal energy consumption under various operation conditions. Based on the results obtained in this study, optimized arrangements of columns, which are applicable as preconditioning step for existing particle separators, are proposed.
