Results are provided for a study of the possibility of selective absorption of HCl and HF from a gas stream also containing H2S and CO2. In order to implement this hydrolysis gas cleaning method, it is proposed to maintain the absorbing solution pH in the range 4-5 by neutralizing excess HCl, for example, by means of adding Ca(OH)2. © 2012 Springer Science+Business Media New York.

A design is provided for uniform gas flow distribution over the length of a layer of activated coal in a radial absorber with a stationary absorbent layer. Calculated results confirmed by experimental data indicate a high degree of absorbent layer utilization. © 2010 Springer Science+Business Media, Inc. Source

Condensation cooling of saturated gases in contact-type heat exchangers installed in gas purification systems is studied. An empirical relationship characterizing saturated-gas condensation cooling efficiency in various types of apparatuses is derived. A method of engineering calculation of saturated-gas condensation cooling in a tubular (hollow) jet-spray scrubber is proposed. © 2012 Springer Science+Business Media, Inc. Source

The effect of dust properties, parameters and composition of gases for cleaning on the choice of synthetic filter materials for bag filters with pulsed regeneration is considered. Particular attention is devoted to cleaning high-temperature moist gases containing corrosive components. Recommendations are proposed for calculating the temperature of the acid dew point of gases being cleaned. Comparative characteristics are provided for synthetic materials produced overseas and used in gas filtration. © 2010 Springer Science+Business Media, Inc. Source
