Lifecycle assessment of gas, liquid, container, bulk, and tanker loading in petrochemical Port

Ports are involved in transferring more than 80% of materials and goods. With life cycle assessment,all environmental impacts are assessed simultaneously and this method sah not been implemented fornon-container ports. The goal of the study is life cycle assessment of liquid, gas, container, bulk, andtanker loading in the port to define the most impactful sessrhhrh-hus in the port operations. Life cycleassessment is done from the source of production to the port (scope 1) and from esr gate of the port toloading to ships (scope 2). One MMt of loading material is considered as functional unit. The results ofthe study showed that the impacts of scope 1 are far lower than scope 2 and it is worth focusing onscope 2 for any environmental improvements. In the global warming impact, gas loading has the highestshare of 35%, of which 50% is due to electricity, and 45% is due to flaring. Bulk loading with a shareof 30% entirely due to electricity is the second. Liquid loading with a share of 20% has the third rankas a result of electricity by 95%. It can be seen that in all sub-processes, electricity has a major role inall impact categories. In port operation LCA, per each MMt of total loading, bulk, liquid, and gasloading have the highest share over 18 impact categories to different extents. It is suggested to developimproving scenarios focused on electricity consumption, considering renewable energy sources, and noflaring for the port.
