Includes Post #231657. You missed an important detail when you looked at the pictures of #3. Note that #2 had 4 condensation towers that were ceramic bat wrapped to prevent employee burns. The new photos of #3 have 8 towers ,4 of which are wrapped. This would suggest that other 4 are not being used at this time. There is enough room for #4 when only the main processors is installed down the second half of the building with no room required for additional towers. All fluids would be discharged from the same side of the building.This is why I thought #4 was planned for that building Also note.(The door at the back of the building was not part of the original structure) (only allowed one message/day)
