Solids holdup and pressure drop in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2003)
Fundamentally based model for pressure drop in gas-flowing solids-fixed bed contactors is presented, together with a phenomenological semiempirical model for prediction of dynamic holdup. These simple models do not require ...
Solids residence time distribution in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2005)
Flowing solids residence time distribution in gas-flowing solids-fixed bed contactors was investigated using a tracer technique with a step signal as input. Particles of different color (all other properties being the same) ...
Modeling and predictions of solids dynamic holdup in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2004)
A model based on first principles and free of any semiempirical parameters is presented for trickling solids holdup in gas-flowing solids-fixed bed contactors. A small double-cone cavity is used to characterize the voids ...
Fast estimation of quasi-steady states of cyclic nonlinear processes based on higher-order frequency response functions. Case study: Cyclic operation of an adsorption column
(Amer Chemical Soc, Washington, 2006)
A new method for fast approximate calculation of quasi-steady states of cyclic processes is presented. The method is based on the concept of higher-order frequency response functions. The system input is represented in the ...
