“…Equation 6.24 indicates that the mass transfer rates are independent of k L and of the hydrodynamic conditions; hence, the whole interfacial area is uniformly effective when gW5. [6] As will be discussed in Chapter 12, any increase in the enhancement factor E due to the respiration of microorganisms can, in practical terms, be neglected as it is very close to unity.…”

The rate coefficient of reaction between liquid Ci8 alpha-olefin and gaseous SO3 dissolved in it is measured by using a pulse method, developed first to measure the film coefficient of mass-transfer in packed beds. To interpret the rate data obtained from the pulse reactor, a criterion is developed based on the penetration theory to approximate the behavior of a rapid second-order irreversible reaction by that of a pseudo first-order reaction. Experimental procedures and the underlying concept of getting rate coefficient by the pulse method are given to apply it to gaseous SO3 absorption by liquid alpha-olefins. The second-order rate coefficient k2 of the reaction for liquid Ci8 alpha-olefin and SO3dissolvedin itisfoundtobe: k2 = 7.7X109exp(-6.2X103/KT)

Absorption, or gas absorption, is a unit operation used in the chemical industry to separate gases by washing or scrubbing a gas mixture with a suitable liquid. One or more of the gas components dissolves or is absorbed in the liquid and is thus removed from the mixture. Absorption is currently one of the most important processes in chemical engineering not only for product recovery but also, and perhaps mainly, for pollutant removal. Intense industrial and academic effort is focused on optimizing the process, in terms process efficiency as well as commercial aspects. In this article, the fundamental principles of gas solubility and mass transfer, design and operation of industrial equipment with relevant examples of typical commercial gas absorption processes are discussed, including recent developments in these areas.
