Mass transfer coefficient in cyclic adsorption and desorption.

experimental investigation of power consumption, mass transfer coefficient and flow regime in gas-liquid dispersion systems

Experimental measurement of heat transfer coefficient and mass of deposited CaSO4 in subcooled flow boiling condition

Fouling is a common, fundamental and costly problem in heat transfer systems, which reduces thermal efficiency of equipment, increases the energy loss and causes strong damage to the heat transfer equipment in various industries. The main causes of fouling on the heat transfer surfaces are salts with inverse temperature-solubility in the fluid which calcium sulfate is one of the most important ...

Investigation of Packing Effect on Mass Transfer Coefficient in a Single Drop Liquid Extraction Column

Adsorption and Desorption of Paraquat

The adsorption and desorption of paraquat (1, l'-dimethyl-4,4'-dipyridylium dichloride) in two tropical soils was determined under laboratory conditions. The two soils were taken from rice fields located in the North West of Perak state. The adsorption equilibrium time was 2 hours for both soil types. This adsorption equilibrium time was used to determine the effect of concentration on adsorpti...

Investigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System

In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
