Fundamentals (Chemical Engineering Practice)

The chemical absorption of CO 2 in solvents is considered as one of the mature process options for reducing CO 2 emissions in power plants. Solvents with fast mass transfer rates and high CO 2 carrying capacity are therefore desired and continue to be explored to reduce equipment size and its...

The term “Appropriate Placement” was introduced in Pinch Analysis during the 1980s to indicate how special unit operations should be correctly integrated with the background process to ensure maximum energy savings. Pinch Analysis has provided guidelines for the design of heat exchanger networks as...

Temperature distribution in activated carbon bed during adsorption of nitrogen (model gas for hydrogen); experiment & mathematical model Agnieszka Truszkowska 1 , Christopher Loeb 1 , Richard Chahine 2 , Bruce Hardy 3 and Goran N. Jovanovic 1 1 Oregon State University, Department of Chemical,...

The effect of solid and gas phase heat recovery on total energy required for an ideal solar-driven carbon dioxide capture cycle based on calcium carbonate/calcium oxide calcination/carbonation is studied. The effect of varying the carbonation and calcination reaction temperatures on total energy...

Thermochemical water splitting presents a way to store thermal energy in the chemical bonds of a H 2 molecule. Besides becoming an increasingly important energy carrier, hydrogen already has vast importance in petroleum upgrading and ammonia synthesis. In an effort to improve the Sulfur-Iodine...

The aim of the present study was to demonstrate the preparation and characterization of planar biomimetic bacterial water-channel protein Aquaporin Z (AQPZ)-incorporated polymer membranes on porous solid substrates by vesicle spreading for water treatment. AQPZ -incorporated polymer vesicles were...

It is often challenging experimentally to determine the mass transfer area, a, in the constitutive equation for the rate of mass transfer, , where is the rate of mass transfer of component A between the phases and . Almost all experiments are designed to determine KMa ,which is an equipment...

Pyrolysis oils derived from lignocellulosic feedstocks by way of fast pyrolysis offer the possibility of a distinct alternative to the use of petroleum-based fuels. However, an inherent drawback associated with pyrolysis oil its high oxygen content which is due to the nature of the lignocellulosic...

We describe a maskless process for the fabrication of nanowells on a silicon substrate using chemically reactive nanoparticles. Positively-charged amidine-functionalized polystyrene latex (APSL) colloids are adhered onto a silicon wafer, and hydrolysis of the particles' amidine groups generates...

Advanced gasification power plants will employ the water-gas shift reaction to produce a high pressure gas-phase mixture containing CO 2 , H 2 and water. This shifted syngas mixture at elevated pressures provides ample driving force for the use of physical solvents that will selectively absorb, but...
