in recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. the hybrid system presented in this article produced power with sofc and stirling engine. the purpose is to analyze a 50 kw solid oxide fuel cell that could produce enough thermal energy for a 10 kw stirling engine working in the hybrid s...

one of the most important methods of transporting natural gas in iran and other parts of the world is the utilization of a network of pipelines. compression station and turbo compressor units play an important role in gas supply through pipelines. one of the primary concerns in these units is the reduction of fuel consumption. by cooling of exhaust gas from the source station, the pressure drop...

This work evaluated the possibility of generating electricity from flared gases through application combined power cycle (Organic Rankine and Brayton circle) which was simulated using Aspen Hysys. The data for stimulation obtained literature in terms process plant operating conditions. results simulation were presented material balance, energy costing, sensitivity analysis exergy analysis, is o...

A standard process for CO2 capture based on absorption in mono ethanolamine (MEA) has been simulated and cost estimated with an equilibrium-based model Aspen HYSYSTM. The aim to calculate optimum parameters evaluate the possibility of automated optimization using a spreadsheet facility. An Excel is used dimensioning estimation specified process. New this work that Visual Basic Application (VBA)...

Various components of air have been separated for different purposes for their easy availability in the atmosphere. Among those components Nitrogen separation process is very important in chemical engineering sector since it has wide usage in different processes. There are various technologies that are used for the separation of nitrogen. Among those most common is via LINDE-HAMPSON cycle. This...

The combined use of heuristics such as expert systems, databases, mathematical process simulators, equipment sizing and cost estimation is a potential way of exploring improved chemical process synthesis. We report on the development of a software that integrates knowledge based system with HYSYS process simulator and Icarus economic evaluator utilising knowledge from existing processes to obta...
