Solvents for Membrane-Based Post-Combustion CO2 Capture for Potential Application in the Marine Environment

Carbon capture on-board ships represents a powerful technological measure in order for the shipping industry to meet very stringent GHG emission reduction requirements. Operation within ship environment introduces number of constraints associated mainly with space, energy supply, and safety which have be addressed using compact yet efficient solutions. To this end, solvent-based membrane CO2 offers several advantages has necessary maturity installation. Solvent choice remains critical issue both reasons process efficiency as well safety. In paper, we present an up-to-date comprehensive review different solvents that can used post-combustion capture. Furthermore, investigated solvents’ performance determined by their inherent characteristics, properties, behavior range operating conditions against strict A preliminary qualitative comparative assessment was carried out based on appropriately selected key indicators (KPIs) pertinent requirements industry. The identified solvent classes were compared most KPIs system integration ship. It concluded at present, no category efficiently address all However, widely such secondary amines showed relatively good compatibility majority introduced KPIs. On other hand, more recently developed molecules, phase change ionic liquids, easily prevail over vast long they are brought same level benchmark solvents. Such conclusion points toward need accelerating research tailor-made performance-targeted
