The neutron scattering device has been successfully developed to measure steam qualtiy in a two-phase steam-water flow. This technique is based on the fact that neutrons lose a significant amount of energy as they collide ...

Recently, an amperometric sensor attached with a hydrogen-selective membrane made of epoxy vinyl ester based resin, Derakane 470-300, coated on a Teflon sheet, has been proposed to measure hydrogen concentration in the ...

In this work, C8 aromatics adsorption in liquid phase on X and Y zeolites was investigated. To study effects of acid-base interaction between the aromatics and the zeolites, a series of both zeolites with differenct exchanged ...

Blends of ESCOR 310 terpolymer, a terpolymer consisting of polyethylene, poly(acrylic acid), and poly(methyl acrylate), and a series of EAA copolymers of different blend compositions were prepared by melt mixing on a ...

Asphaltenes precipitated from curde oil during production, transportation, and the processing process cause serious problems in the petroleum industry. This study focused on determining of solubility of the asphltenes ...

This work studied the effect of ions present as hardness in tap water, i.e. calcium, magnesium, hydrogen carbonate and hydrogen sulfate ions, on the foaming properties of three surfactant systems. The first system consisted ...

Systems involving gas-liquid phase concurrent vertical flows are found important in evaporators and in the simultaneous transport of oil and gas in wells. For the two-phase flow study, flow regimes and the hydrodynamics ...

The molecular designs and syntheses of aza-methylene phenol compounds enhanced with (i) hydrophobic and (ii) hydrophilic groups are proposed. The ring opening reaction of benzoxazine is applied to preepare the aza-methylene ...

Hydrogen is an important raw material in many chemical processes. It can be used as feedstock in Fischer-Tropsch process in order to produce transportation fuels and other liquid products. Moreover, it can be used as the ...

Silatrane synthesized from inexpensive precursors, silica and TEA, was used as the precursor for MCM-41 synthesis at low temperature because of its stability in aqueous solutions. Using cationic surfactant cetyltimethyl ...
