bar (200 psig), the flashing cools the LNG to – 115°C. It is then passed back through the cold box warming to ambient conditions against the pentane flowing counter currently with the result that the pentane is cooled to – 105°C. A simplified process flow diagram is shown inFig 10...
As shown in the flow diagram, LNG from the storage tank is pumped by the low pressure LNG pump to an intermediate pressure such as 100 psig, and then pumped by the high pressure LNG pump to supercritical pressure, typically 1650 psig or higher. LNG is then heated and partially regasified...
Regarding the open cycle supplied by NG, a part of the LNG regasification is carried out by exploiting condensation heat released from R717 in the HE2 heat exchanger; the process is completed by means of the seawater flow rate that evolves in the HE3 heat exchanger. R717 superheated steam ...
(AAH),where it regains the required heat from ambient air and then returns back to the STV,forming a closed loop.FIG.1 shows a typical pro-cess flow diagram for an LNG regasification terminal with an STV with a glycol-water mixture as the intermediate fluid and an AAH as the primary ...
and the circulation connection line, and the tank connection line supplies a fluid inside the seawater storage tank on the circulation connection line before the seawater flowing in the seawater discharge line is switched to flow the circulation connection line without being discharged to the outside...
High pressure liquid stream 13, at a flow rate 6,000 gpm, typically at 40° F. and 180 psia to 380 psia, is vaporized and superheated in superheater 57 to about 60° F. to 150° F. forming stream 4 that is expanded across the high pressure expander 53 to about 100 psia. Generator...
Moreover, as can be seen in the 1ORC-OC, the maximum NG flow rate in the OC depends on the properties of this fluid in the CD-1 condensation process, with a more than double resultant value if the LNG from Supplementary Table S2 is used. In summary, there are only two cycles that...
Figure 5. ORC fueled by R170 in the T-s diagram with LNG and seawater as thermal sources (reference conditions s0 = 3.3256 kJ/kg·K at p0 = 0.01 bar and T0 = 298.15 K). Table 6. Thermodynamic points of the ethane-fueled ORC. Again, preliminarily, the ethane flow rate can be de...
