The site design was faced with some challenges as well. Much of the area surrounding the site is in a coastal flood plain. Because of this and as a result of requests from Greenville's insurance carrier, Factory Mutual System, the control building, storage tanks, access road and major equipment were raised to be on foot above the 500-year flood elevation. This required significant impact on the site design, particularly regarding LNG spill containment. An LNG transport unloading skid is provided with vapor and liquid connections and pressure controls for top and bottom fill of the tanks.
Vaporization is located within the impoundment system.
This vertical shell and tube heat exchanger is provided with a tube arrangement surrounded by a single shell. The vaporizer is operated based on flow control. The desired flow rate is obtained by operating the LNG flow control valve. Liquid differential is measured using an orifice plate and the liquid flow rate is converted to Mcfh. To raise or lower the flow the operator need only change the desired output.
