Gas hydrates attracted worldwide attention due to their potential as huge energy resource in the recent decades. Effective parameters which influence the formation of hydrates are high pressure, low temperature and water presence. HYSYS software is one of the major simulators which are widely used in the chemical and thermodynamic processes. This research was conducted to simulate gas hydrate f...

Process simulators are becoming basic tools in chemical engineering programs. Senior-level design projects typically involve the use of either a commercial simulator or an academic simulator such as ASPENPLUS, ChemCAD, ChemShare, FLOWTRAN, HYSYS, and ProII w/PROVISION. Many design textbooks now include exercises specifically prepared for a particular simulator. For example, the text by Seider, ...

HYSYS process modeling software was used to analyze the effect of reflux ratio and number of trays on the purity of ethylene in a vapor recompression distillation column and also in an ordinary distillation column. Analysis of data showed that with increased pressure a higher reflux ratio is needed to obtain a purity of 99.9% for both towers. In addition number of trays was varied to see its ef...

The article provides an overview of knowledge on how to model fuel cells using software which is oriented system modeling. covers several types cell such as SOFC, MCFC and PEMFC. Fuel were modeled mainly three software, i.e. Aspen Hysys, Plus Matlab. Based our literature review, we decided use Hysys create a proton conducting SOFC model. Model construction based reduced order approach that publ...

This work presents the results from dynamic modeling and control of an azeotropic distillation system. The model was validated with experimental data from a packed distillation unit. The physically-based process dynamic model, developed in HYSYS, was linked online with the control software used in the process. Model parameters were modified online using a feedback configuration to eliminate the...

In this time of energy crises, low production rate against the increasing demand of oil and gas production regularly hampers both domestic and industrial operations. In addition, safety hazards arising from explosion and increase in the cost of production due to pumping cavitation has pose a great challenge on offshore Floating Production Storage and Off-loading (FPSO) terminals. In view of the...

Methanol is one of the most important petrochemical products which is produced in large extents worldwide. Nowadays, it is mostly used as a feed in olefin units for production of synthetic fuels. In this work, methanol production process, under license of Davy Corporation, is simulated by using HYSYS software. The simulations are carried out for steady state condition. The simulation results we...

A dynamic model developed in the HYSYS process simulator was validated using experimental data obtained from a pilot scale cyclohexane / n-heptane distillation. The resulting model was linked to the pilot unit’s DeltaV (Emerson Process Management) process control software. This link allowed non-measured parameter estimation to occur in parallel with the operation and control of the pilot plant ...
