Data for the volumetric mass transfer coefficient, kLa, and the effective area, of structured packings have rarely been reported in the literature. This is despite the ever-increasing importance of structured packings in industrial separation columns for a ...
Intube flow boiling experiments for refrigerant R-134a mixed with a lubricating oil are reported. The tests were run at a nominal inlet pressure of 3.4 bar over a wide range of vapor qualities at mass velocities of 100, 200 and 300 kg/m2s (73500, 147000 an ...
It has been shown in a number of studies that the Kalina cycle can have considerably higher efficiencies than the Rankine cycle. An especially advantageous application is as a bottoming cycle to a gas turbine. In this paper a gas turbine topping cycle has ...
Woven fibrous materials are proposed as structured catalysts for three-phase catalytic reactors. The design of a catalytic bed arranged as a plate bubble column is discussed. The hydrodynamic parameters, like pressure drop and liq. hold-up were found to de ...
The effective area for mass transfer of the Sulzer structured packing Mellapak 125.Y, 250.Y, and 500.Y was measured under industrial-scale operating conditions, with a broad range of gas and liq. flows, in a pilot plant with a column having an internal dia ...
Spectroscopic monitoring techniques have many advantages for bioprocess monitoring and control, including simultaneous multi-analyte detns., in-situ sterilizability, and low maintenance during operation. This study discusses the combined application of flu ...
The solubility diagram of the quinary system Na+-Mg++-1-aminonaphtalene-6-sulfonate-1-aminonaphtalene-7-sulfonate-Cl–-H2O has been partially investigated between 0° and 75°. From this diagram a simple and effective procedure to separate the two CLEVE'S aci ...
The correlations available in the literature cannot be used to est. the liq.-phase mass-transfer coeff. (kL) for viscous solns. Even correlations that agree for water-like viscosities diverge by an order of magnitude for viscosities of only 10 mPa-s. Here, ...
A review is given of gas absorption which is generally used for the gas with the liq. Gas solubilities and mass transfer concepts used in the design of absorption columns (e.g. Kremser-Brown method), film factor concept, penetration theory, and Chilton-Col ...
