the purpose of this project is the study of the natural gas {methane)steam reforming process through modeling and computer simulation. the operating parameters will be determined and then the? effect of changing these parameters on the conversion and purity of the final products will be studied. using computer simulation. the effect of the change in parameters will be studied along the lenght o...

Advanced zero-gap alkaline electrolyzers can be operated at a significantly higher current density than traditional electrolyzers. We have investigated how their performance is influenced by diaphragm thickness, temperature and pressure. For this semi-empirical current-voltage model has been developed based on experimental data of 20 Nm3/h electrolyzer. The was extrapolated to thinner thickness...

This paper investigates effects of different additives on morphology and subsequently, separation performance of asymmetric flat sheet Polyvinylidene fluoride (PVDF) membranes to separate CO2 using membrane contractor. Five different additives from different chemical families including Lithium chloride (salt), Polyethylene glycol 400 (polymer), glycerol (weak anti-solvents), methanol...

AbstractThe purpose of this study was to investigate the controllable operating parameters influence, including pH, solid content, collector, co-collector, and depressant dose, and conditioning time, on apatite flotation kinetics. Four first order flotation kinetic models are tested on batch flotation time-recovery profiles. The results of batch flotation tests and the fitting of first-order ki...
