Scalloping, a texturing of a corroding surface that imparts the appearance of orange peel, is commonly observes in the area exposed to the flow assisted-corrosion. the effects of surface scalloping on flow hydrodynamics ...

Froth flotation is a surfactant-based separation process which is suitable for treating a dilute oily wastewater. The objective of this study was to investigate the effects of certain opreational parameters on the separation ...

An effective way to reduce energy usage in a refinery is to design efficient heat exchanger networks (HENs) by using process optimization on the Mixed Integer Liner Progeaming (MILP) method. In this work, retrofit designs ...

Two types of adsorbents, activated alumina and molecular sieve zeoite 4A, used in the natural gas dehydration process were studied for their adsorption behaviour, both static and dynamic along the adsorption process. ...

The formation of petroleum emulsions during oil production is a costly problem. Petroleum emulsions have to be treated to meet crude specifications that water content must be less than 0.5% by volume. Chemical demulsification, ...

KL zeolites with cylindrical shape are effective catalyst supports for noctane aromaticzation, but the effectiveness strongly depends on the channel length of the zeolite crystallite as well as Pt dispersion and location ...

The conversion of glycerol to aromatic hydrocarbons was investigated over modified HZSM-5 zeolites. The catalytic activity was carried out in a continuous flow fixed-bed reactor at 400 ºC, 300 psig and H₂/feed molar ratio ...

Koh Samed sand, which contains mostly calcium carbonate, was chosen to prepare a porous hybrid composite because it is cheap and non toxic. High molecular weight poly(vinyl alcohol) (PVA) was used as an organic phase, while ...

In this study, polyaniline (PANI) was synthesized via oxidative coupling polymerization in acid conditions and its condutivity was controlled by doping in camphorsulfonic acid (CSA) solution and de-doping in solution of ...
