Techno-Economic Analysis of Selexol and Sulfinol Processes for Pre-Combustion CO 2 Capture
2018 International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET), 2018Co-Authors: Neelam Ramzan, Usama Shakeel, Afsin Gungor, Muhammad ZamanAbstract:One of the reasons for global warming and climate change is the anthropogenic CO 2 release into the air, especially when low quality coal is used. So there is the basic need to mitigate the emissions of CO 2 to avoid the global warming. To decrease the amount of CO 2 being released into the air in near future, the carbon capture and storage is now considered an effective and practical way. Integrated gasification Combined cycle (IGCC) power plants are considered relatively advanced fossil fuel based power generation system due to higher net power efficiency, ease in CO 2 capture and cogeneration opportunities. Liquid absorption is the widely used and matured technology for gas separation. Physical solvents are mainly used for pre-combustion CO 2 capture. The main objective of this paper is to search the most suitable solvent or combination of their mixture. Performance comparison and economic evaluation for two different physical solvents including Selexol Process and Sulfinol Process has been made for the optimal selection of the capture Process. The performance of Sulfinol hybrid solvent (a mixture of Sulfolane, MDEA and H 2 O) is compared with the Single Stage Selexol Process. When both the Dual Stage Processes were compared, Dual Stage Selexol was found to be economical over Dual Stage Sulfinol Process.

Enhancement of carbon dioxcide (CO2) removal Process in liquefied natural gas (LNG) production system
2010Co-Authors: Mohd Firdaus, Che Ros IsmailAbstract:Removal of CO2 from natural gas is currently a global issue, apart from meeting the customer's contract specifications and for successful liquefaction Process in any LNG project, it is also a measure for reducing the global CO 2 emission. The aims of this research are to present a comprehensive review for removal of CO 2 from natural gas to meet LNG production specifications and explore the capability of Aspen HYSYS Process simulator to predict the CO 2 removal Process. A base case of typical CO2 removal Process is used to create a steady-state simulation using Aspen HYSYS 7.0 Process simulator. Then, the simulation program is developed (Sulfinol Process model) to modify the physical, thermodynamics and transport properties of the gas and the Process units involved to improve Process performance. Next, the constructed model was then validated against the existing plant data, which in turn provide information on potential problem areas within the current simulation Process. Moreover, the model was then used to determine the CO 2 removal efficiency, maximize the heavier hydrocarbon recovery and reduce the power consumption at the optimum Sulfinol hybrid solution composition. The best optimum simulation result shows that increasing of CO 2 capturing capacity in the Sulfinol contactor to almost 84 percent. This Process also met the LNG product specifications which is 1.69 mole percent of CO 2 in the LNG product stream and the reduction to about 11.14 percent of carbon dioxide slippage in sweet gas stream. In term of economics, this Process can safe heat consumption at stripper reboiler up to 18.39 percent and power consumption at pump up to 6.68 percent. For the heavier hydrocarbons recovery, this Process can recover to almost 8.89 kgmole per hour. As a conclusion, this research has achieved its objectives which are to improve the carbon dioxide removal Process and also to model Sulfinol Process model in Aspen HYSYS simulator. It is recommended to run a sensitivity analysis of this model when the feed to AGRU is increased in the case of "bottleneck" conditions.
