Herein, a biomethane liquefaction process followed by CO 2 solidification is presented. The CO 2 solidification phenomenon is studied using the Aspen Hysys v11 and validated against available experimental data.
In the process model, the waste LNG cold energy is recovered at the lean amine cooler in the CO2 capture process and each heat exchanger in the CO2 liquefaction process. Furthermore, for CO2 regeneration, the waste hot energy from NGCC is recovered at the stripper reboiler. The exergy and ...

A CO 2 liquefaction cycle i.e., ammonia-water absorption system is developed using the heat waste of the flue gas. Process modeling is developed in Aspen Hysys v.10 software with the aid of Peng-Robinson equation of state. Energy, exergy, economic and exergoeconomic analyses are then ...
A low-temperature process reducing the CO2 concentration from an initial50.6 vol-% to LNG specification (50 ppm) has been simulated in Aspen HYSYS. Main results such as product streams, power consumption for auxiliary refrigeration and steam requirements have been estimated. The process delivers the...
desalinated water, and oxygen Process simulation using Aspen HYSYS v10, with energy and exergy analysis and economic assessment Methanol was efficiently produced at 0.124 $/kg using water electrolysis and biogas upgrading, with CO2 capture and gas turbine cycles accounting for 80 % of exergy destru...
The process simulation and heat and mass balance calculations were carried out using the ASPEN HYSYS process simulator. The heat and mass balances obtained from the converged simulation are utilized for exergy and energy calculations in a separate spreadsheet. The Peng–Robinson equation of state is ...
A portion of the CO2 captured from the air is delivered to nearby greenhouses for vegetable fertilization, while another portion, after liquefaction, is transported to the beverage industry for utilization. The three DAC projects in Iceland are all based in Hellisheidi, using renewable energy such...
