Gas Chromatography (GC) is a mature analytical technology used predominately for separating and quantifying the components of complex organic chemical mixtures. A wide range of columns and sample introduction techniques allow GC to be applied to most analytical problems involving volatile and semi-volatile compounds. One such application is the analysis of permanent gases, which are compounds t...

The Present work was inspired by a small note published in science reporter.Keeping the concept in mind , the subject is explored further and its application in the f...

Cytochrome P-450 mono-oxygenase enzymes play a key role in the oxidative transformation in living systems. As one kind of cytochrome P-450 models, metalloporphyrins have been widely used in selective oxygenation of hydrocarbons under mild conditions. The chapter focuses on reviewing the biomimetic homogeneous oxidation of organic compounds catalyzed by metalloporphyrins with green oxidants such...

Various organic solutions are used in many industries such as the petrochemical industry. The presence of moisture in those solvents results in poor insulation, corrosion of apparatus and catalyst poisoning. Therefore, the moisture content of the solvents must be reduced to less than several ppm. Since ion exchange resins have an ability to adsorb selectively polar substances fromnonpolar solve...

This research involves the design and analysis of pinch-based water/wastewater networks to minimize water utility in the petrochemical and petroleum industries. A study has been done on Tehran Oil Refinery to analyze feasibilities of regeneration, reuse and recycling of water network. COD is considered as a single key contaminant. Amount of freshwater was reduced about 149m/h (43.8%) regarding ...

Catalysts play a pivotal role in modern industries, especially in the petrochemical industry, such as in the processes for production of advanced materials such as carbon nanotubes. Since the discovery by Iijima in 1991, carbon nanotube has received increasing interest worldwide owing to their unique structural, electronic and mechanical properties [1], and their promising applications in molec...

There has been a recent surge in the number of disasters and incidents in occurring in the process industry (e.g. the petrochemical, chemical, food and pharmaceutical industries). The reasons include defects in process-safety management (PSM); inadequate safety management systems in companies; inadequate knowledge among managers and insufficient information about the tasks undertaken and result...
