Recovery of Ionic Liquid from Aqueous Phase Pyrolytic Oil: A Simulation Using ASPEN HYSYS V10

Process Simulation and Optimization of Crude Oil Stabilization Scheme Using Aspen-HYSYS Software

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...

Biodiesel production from soybean oil using ionic liquid as a catalyst in a microreactor

In the present study, Choline hydroxide (ChOH) as an ionic liquid catalyst was used for transesterification of soybean oil into biodiesel in a microchannel reactor. The effects of three variables i.e. reaction temperature, catalyst dosage and total flow rate on fatty acid methyl ester (FAME) content (wt. %) were optimized using Box–Behnken experimental design. In order to predict the FAME conte...

Analysis and Modeling of Vapor Recompressive Distillation Using ASPEN-HYSYS

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...

Estimation of Power Production Potential from Natural Gas Pressure Reduction Stations in Pakistan Using ASPEN HYSYS

Pakistan is a gas rich but power poor country. It consumes approximately 1, 559 Billion cubic feet of natural gas annually. Gas is transported around the country in a system of pressurized transmission pipelines under a pressure range of 600-1000 psig exclusively operated by two state owned companies i.e. SNGPL (Sui Northern Gas Pipelines Limited) and SSGCL (Sui Southern Gas Company Limited).
