The article shows examples of the use Aspen Hysys software for optimization AVT-3 and AT-2 crude oil distillation units at Atyrau Oil Refinery. was implemented Refinery first time.Calculations were carried out to optimize refinery with construction a model in Hysys. As result calculations, possibility improving efficiency individual parts revealed, pilot runs on confirm. During run unit, restri...

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)...
