suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

15 صفحه اولsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Aqueous urea solutions: structure, energetics, and urea aggregation.
Urea is ubiquitously used as a protein denaturant. To study the structure and energetics of aqueous urea solutions, we have carried out molecular dynamics simulations for a wide range of urea concentrations and temperatures. The hydrogen bonds between urea and water were found to be significantly weaker than those between water molecules, which drives urea self-aggregation due to the hydrophobi...
متن کاملThermal gelation of chitosan in an aqueous alkali-urea solution.
Chitosan can readily dissolve in a precooled aqueous alkali-urea solution, a solvent that has previously been developed to dissolve cellulose. Upon heating, the resulting solutions quickly become a gel. The thermal gelling of the chitosan solutions was studied by rheology. Initially, a temperature ramp test was used to determine the gelation temperatures (Tgel). It was found that Tgel does not ...
