In recent few years, some endogenous and exogenous barriers caused different challenges in oil and gas project financing. Since appearance and development of innovative ideas such as DLT and blockchain in financial business models, this methods are replacing with traditional models. A blockchain is a decentralized, distributed and oftentimes public, digital ledger consisting of records called b...
Background and aims: In spite of industrial safety’s developments in Iran, construction safety is not in desirable level and needs to be evaluated from different aspects. The aim of this study was to evaluate safety climate structure in construction projects and its effect on safety performance and accidents frequency rate. Methods: This study was conducted at 4 construction projects. ...
Methane is a hydrocarbon compound that can be used for various purposes. Currently, methane widely as fuel, and continues to developed synthetic gas material petrochemical products have added value, one of which formaldehyde. This study aimed the partial catalytic oxidation reaction formaldehyde using MoO 3 /zeolite catalyst. Reactant stream consisting pure O 2 CH 4 were contacted with rate rat...
buy-back contracts in the upstream oil and gas projects of iran, has experienced the third generation of this kind of contracts since its inception on 1373 (1994) when the oil and gas industry of iran opend its petroleum market to the foreign investment. these contracts have since been subject to the various critieques raised by international oil companies, foreign investors, or petroleum exper...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...

Model-based advanced process control strategies are common applications in the hydrocarbon processing industry. A close look at the references available in literature reveals that the overwhelming majority of these projects are concentrated in refineries and in some specific petrochemical plants (e.g., ethylene). This is due to the excellent economic returns demonstrated in an abundance of expe...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
