Design and Analysis of Novel CO2 Conditioning Process in Ship-Based CCS

In this work, CO2 conditioning processes for ship-based CCS sequestration are modelled using the software APSEN HYSYS V11. This study uses captured gas from 3D project as feed. The feed stream contains water, H2S, and CO contaminants. purification dehydration, desulfurization, removal reviewed. Two liquefaction approaches, open-cycle closed-cycle liquefaction, compared transport pressures 7 15 bar. It is found that energy requirement of process higher than process. For design, two refrigerants, ammonia propane, considered. Results show lower propane. When comparing pressures, it at bar requires less On top that, both refrigerants unsuited bar, their operating below 1 atm. Several optimization concepts tested on design. net power consumption reduced when precooled intermediate pressure streams cold stripper.
