The Freeport LNG Receiving Terminal, Texas
First LNG Receiving Terminal Using the Air Tower Patented Process in Production Scale
Description of the Project - Phase I
Freeport LNG will utilize the closed-loop recirculation system with a “reversed cooling tower” commonly referred to as air tower. This will enable the regasification terminal to take advantage of the high ambient temperatures and high humidity conditions in the Texas Gulf Coast region.
Historically, air towers have been used to reduce the heat of an industrial process system by exchanging the higher temperature of the process cooling system with the lower ambient temperature. However, the Freeport LNG air tower will serve as a heating function, providing vaporization heat during normal conditions. As a result of the use of the closed loop system, for approximately nine months of the year, the air towers will provide all of the heat required to regasify LNG.
For the remainder of the year, the fired indirect heaters will act as a supplemental heat source for the vaporizers with the air towers providing varying amounts of the heat depending upon local weather conditions. These fired heaters will also provide 100% backup vaporization capacity for the facility during the winter period.
Send-out capacity:
1.5 Bcf/day, peak 1.75 Bcf/day
