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...

Abstract The application of biodiesel will increase in accordance with the government’s mandatory program for saving fossil fuels. challenging would come from particulate levels and water content. One efforts to fix issues is by adding rhodinol citronella oil as an additive. This research was conducted design a vacuum distillation process which has 500L capacity determine fractionation unit. Si...

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...

Recently, Japan and the European Union have been experiencing declining petroleum demand owing to global initiatives aimed at reducing environmental impact by curtailing CO2 emissions. Consequently, alternative products operational conditions should be developed utilize fluid catalytic cracking (FCC) unit. Using simulation software (Aspen Hysys), this study modeled a typical FCC unit compared r...

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)...

Dew Point Control Unit (DPCU) merupakan salah satu unit utama yang penting dalam proses pemurnian gas alam. Terbentuknya metana hidrat di DPCU menjadi masalah dihadapi ketika suhu operasi diturunkan serendah mungkin pada tekanan tinggi. Untuk mencegah terjadinya pembentukan tersebut, diperlukan adanya injeksi glycol. Jenis glycol digunakan oleh Gajah Baru Central Process Platform (GBCPP) milik ...

Distillation columns are complex processes for modeling and controlling. These columns are significant parts of most chemical industries for separation of components. Control of this process is essential for achieving certain purity for products with a minimum cost. However, nonlinearities, multivariable interaction, non-stationary behavior and severity of disturbances inside the column made th...
