Energy, exergy, economic and environmental (4E) analysis of an integrated process combining CO2 capture and storage, an organic Rankine cycle and an absorption refrigeration cycle

•The integration process of CCS with ORC and ARC is proposed.•The energy, exergy, economic and environment analysis of the process are carried out.•The exergy efficiency of the waste heat utilization system is 42.88%.•The total annual cost of integration process is 72% lower than that of basic CCS.•LCA results show that equivalent CO2 emission of the process is 2.03 kg CO2-eq/t.
