The application of Pinch Analysis (PA) targeting method has been recently explored to the design of CO2 emission reduction in Total Site planning of CO2 capture, utilisation and storage. The algebraic method based on Problem Table Algorithm (PTA) for Total Site CO2 Integration (TSCI) provides the designer with integrated CO2 capture, utilisation and storage (CCUS) for the optimal CO2 emission reduction. In TSCI, CO2 is captured with certain quality from various plants and supply into system header pipeline. The CO2 header could satisfy various CO2 demands for various industry located in the header, and only surplus CO2 is to be sent to storage. The extended methodology with consideration of purification and pressure drop in TSCI planning is proposed. The CO2 supply from the header could satisfy the purity demand through a process of purification. Purification is a process to upgrade the purity level have not been considered in the previously used in TSCI method. In addition, pressure drop during CO2 transportation in the pipeline system has been included to identify the implication of pressure drop in TSCI design and has resulted about 29.01 MPa of the total pressure drop (?Pd). Therefore, 68.2 t/h of flow rate (FT) of 81 % purity level header is supplied and purified to satisfy the 50 t/h of demand, at 99 % purity level. The improved methodology of TSCI network has been further developed and provides a more realistic scenario for CCUS implementation.
