PT XXYZ is an oil and gas industry company that a downstream company, namely processes crude into various products are ready to be transferred the market. Oil companies, especially XXYZ, certainly faced with challenges need related future business continuity, in form of challenge substituting fossil sources environmentally friendly energy followed by rapid technological developments. also alway...

Abstract The exergy analysis method is an important for evaluating energy levels and efficiency. It of great importance in the direction process efficiency optimization. In this paper, use coal-to-ethylene glycol distillation comprehensively evaluated analyzed using. Firstly, based on Aspen Plus simulation, basic data were obtained; secondly, a detailed results showed that deethylene unit was l...

Biodiesel is a fuel made from vegetable oils, animal fats and microbial oil (algae, bacteria and fungi). The raw materials are converted to biodiesel through a chemical reaction involving alcohol and catalyst. The purpose of the present work is to present an efficient process using reactive distillation columns applied to biodiesel production. Reactive distillation is the simultaneous implement...

Forensic scientists use various techniques to separate accelerants from fire debris samples before instrumental identification of added fuels. Among the choices available, traditional micro-distillation, steam distillation, vacuum distillation, headspace, heated headspace, and several vapor adsorption/desorption methods provide various advantages and disadvantages. This communication reviews th...

The genus Boswellia is one of the 17 genera belonging to Burseraceae family. In this study resin of Boswellia carteri birdwoodcollected or purchased from Tehram herbal Market as a food and non-food for chemical analysis. The essential oils of the resins of Boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation...

Abstract This paper presents the nonlinear dynamic analysis of an ideal two-reactant-two product reactive distillation. The impact of disturbance magnitudes and directions on openloop stability of the system is studied. An analysis of the physicochemical phenomena present in reactive distillation processes that, under certain operational conditions, causes special types of nonlinear behavior is...
