Research on Design and Operation Optimization of New Model Onboard Carbon Capture System Based on MEA
摘要
Focusing on the effective reduction of carbon emissions in Onboard Carbon Capture and Storage (OCCS), and taking into account the requirements of low energy consumption, small installation space, and high capture rate of actual ships, we have designed and developed an OCCS that uses Monoethanolamine (MEA) as the absorbent and can utilize Liquefied Natural Gas (LNG) cold energy. Aspen HYSYS was used to simulate the OCCS process flow and optimize operating parameters. The results showed that the OCCS capture rate after simulation optimization reached over 70%, meeting the International Maritime Organization (IMO) greenhouse gas emission reduction requirements; Design and select the structural dimensions of key OCCS equipment to further reduce the installation space of the system on board, providing more ideas and reference basis for the deeper research and promotion of carbon capture technology for commercial ships.
