Reverse osmosis desalination water plants have several operational issues such as corrosion in many areas like energy recovery devices that are accustomed to restore energy and scale back prices. Thus, there is a necessity to reduce the corrosion rate of the devices utilized in energy recovery. This study focuses on protection of some metals and […]
The corrosion inhibition of mild steel in 0.5 M hydrochloric acid by six synthesized heterocyclic compounds was studied using weight loss measurements. The inhibition efficiency exceeded 95%. The excellent inhibitor performance was attributed to the formation of protection adsorption films on the steel surface. The structures of compounds were confirmed by Fourier transform infrared and nuclear […]
Heat stable salts such as total organic acids (TOA) and heavy metals are well known contaminants in the acid gas removal systems operating using alkanolamines such as methyldiethanolamine (MDEA, 50 wt%). Decontamination of TOA and heavy metals from lean MDEA always remain as a challenge to the gas industry, as accumulation of TOA deteriorates the solvent […]
The present work proposes the study of the extract of Senecio anteuphorbium (SA) as green corrosion inhibitor. This inhibitory effect of SA extract on the corrosion of S300 steel in hydrochloric acid 1 M has been evaluated by using the potentiodynamic polarization and electrochemical impedance spectroscopy. From the outcome of the polarization curves, SA extract acts […]
Preparation and application of CoMgAl-hydrotalcites have been studied. In this paper CoMgAl-LDHs photocatalysts were prepared by co-precipitation. Various techniques such as UV–visible spectrometry (UV–vis), BET, differential thermal gravimetric analysis, scanning electron microscopy analysis and X-ray diffraction were used to investigate the catalytic activity, structure, and composition of the prepared samples. The photocatalysts were developed as […]
One of the leading routes for producing polyolefins is through gas-phase catalytic fluidized bed reactors. In this study, the industrial gas-phase ethylene polymerization reactor series of Jam Petrochemical Company has been dynamically analyzed, modeled and controlled. The copolymerization of ethylene with 1-butene is defined on Zeigler–Natta catalyst, assuming a double active site mechanism. To serve […]
Aniline is used by many industrial organizations and is released into the environment in high amounts and pollutes the water. Due to the damages to human health, there is a need for effective and environmentally friendly methods to remove this compound from the water. The aim of this work is to mineralize and remove aniline […]
Porous magnesium oxide was synthesized by a combustion method, with Mg(NO3)2, ethylene glycol and deionized water as reactants, and characterized by X-ray diffraction, infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and nitrogen sorption/desorption. The results showed that the as-prepared porous magnesium oxide has the multi-scale porous size with a large BET surface area of […]
A new hetero-Fenton type GO/Fe2V4O13 was developed and characterized by FT-IR, XRD, HR-SEM, TEM, and UV-DRS analysis. XRD pattern reveals the presence of monoclinic phase of Fe2V4O13 in the catalyst. TEM images show the particle sizes in the range from 20 to 100 nm and the nice dispersion of nanosized Fe2V4O13 particles on the surface of […]
The use of fermenters at large scale is usually hampered by sub-optimal conditions in terms of yield and productivity, along with the low tolerance of strains to process stresses, such as substrate and product toxicity, and other fermentation inhibitors. Attempts to improve the industrial efficacy of fermenters have been in the areas of genetic engineering […]
