Trickle-bed reactors
TL;DR: Trickling filters have been used for removal of organic matter from wastewater streams by aerobic bacterial action as discussed by the authors, where biological growths are allowed to attach themselves to a bed of stone or other support over which the wastewater is allowed to trickle in contact with air.

Mass-Transfer Rates in Gas-Liquid Absorbers and Reactors
TL;DR: In this paper, the authors present the techniques, results, and opinions on mass-transfer coefficients and interfacial areas in most types of absorbers and reactors in a gas-liquid mass transfer with chemical reaction.

Trickle-bed reactors: state of art and perspectives
Agostino Gianetto,Vito Specchia +1 more
TL;DR: Theoretical and phenomenological aspects of trickle-bed reactors as reported in a wide number of papers of the last 35 years have been reviewed in this article, where several engineering topics have been focused by trying a critical interpretation of the attained results.

A two-fluid hydrodynamic model for the transition between trickle and pulse flow in a cocurrent gas–liquid packed-bed reactor
TL;DR: In this article, a two-dimensional hydrodynamic model of cocurrent gas-liquid downflow through packed-bed reactors operating in the trickle flow regime is developed on the basis of a mechanistic approach.
Journal ArticleDOI
A new, improved liquid hold-up correlation for trickle-bed reactors
TL;DR: In this article, the authors derived a correlation for the liquid hold-up in a trickle-bed reactor, derived from fundamental considerations and a wide-ranging data base of some 5000 hydrodynamic experimental results.

Journal ArticleDOI
Two‐phase concurrent flow in packed beds
TL;DR: In this article, pressure drop and liquid saturation data were obtained in terms of the single-phase friction losses for the liquid and the gas when each flows alone in the bed and deviations from the correlation with foaming systems were discussed and illustrated with sample data.
Journal ArticleDOI
Chute de pression pour des écoulements à co-courant dans les colonnes à garnissage arrosé: comparaison avec le garnissage noyé
TL;DR: In this article, a co-courant is defined as a condition d'etablir correctement les bilans d'energetic (et non les bilane des forces) dans les fluides en ecoulement.
