WebCSTR, mass transfer model Over 25 years ago the coking factor of the radiant coil was empirically correlated to operating conditions (48). It has been assumed that the mass transfer of coke precursors from the bulk of the gas to the walls was controlling the rate of deposition (39). Kinetic models (24,49,50) were developed based on the chemical … Webmass transfer is dominating and the volumetric mass transfer coefficient is approximated by kLa. The K La depends on numerous parameters, including liquid phase properties, reactor geometry and operating conditions. The volumetric mass transfer coefficient kLa is a critical parameter in the design of reactors and aeration systems. During the ...
