| Popis: |
The evaluation of the mixing zone as part of the EIA for a proposed two-train (55,000 m3/hr) and four-train (135,000 m3/hr) flow rates of seawater at the RasGas liquefied natural gas (LNG) facility on the northeast coast of the State of Qatar was done through the use of Generalized Environmental Modeling System for Surface waters called GEMSS. The cooling seawater absorbs heat during the liquefaction of natural gas resulting in a maximum temperature rise of 10~ The heated seawater is discharged through a long canal into the Arabian Gulf with minimum jet momentum. The model was calibrated and verified and then applied to model the thermal plume for two-train and four-train operations of the facility. A probabilistic approach of defining the mixing zone using the World Bank Standards was developed and applied to the facility. Model results show that the thermal plume from the discharge is vertically stratified, with a relatively large surface area and a relatively small bottom contact area. The advantage of this design is that it maximizes heat exchange with the atmosphere (the ultimate heat sink) by increasing the driving force and isolating the temperature increase from benthic organisms. |
