| Abstract |
This study focused on safety aspects surrounding energy consumption in the seawater desalination process in the Daesan Industrial Complex located on the West Sea coast. The safety index for energy consumption was evaluated under different salinities and
temperatures of the incoming seawater. Temperature and salinity input data for the 1997?2018 period were obtained from the Marine Environment Information System, and the power required for reverse osmosis (RO) was applied to the program as per the data provided by the RO membrane manufacturer (Q-Plus v3.0). Notably, reasonable energy consumption guidelines were proposed during the design of the desalination facilities; in this regard, the desalination process required approximately 2.10?2.90 kWh/m3 electrical power. Moreover, the energy safety based on 95 % was estimated to be 2.80 kWh/m3 when the desalination facility was operated. |
