Available power generation cycles to be coupled with the liquid natural gas (LNG) vaporization process in a Spanish LNG terminal

Optimizing natural gas reciprocating expansion engines for Town Border pressure reduction stations based on AGA8 equation of state

“…At TBSs, the pressure is reduced from 1.7 MPa (approximately 250 Psi) to 0.4 MPa (approximately 60 Psi) by employing throttling valves, which waste large amount of pressure energy (availability). Several methods have been proposed for recovering this huge wasted energy (Querol et al, 2011;Farzaneh-Gord and Deymi-Dashtebayaz, 2009;Chaczykowski et al, 2011;He and Ju, 2014;Farzaneh-Gord and Kargaran, 2010;Farzaneh-Gord and Sadi, 2008;Rosen and Scott, 1998). …”

Power plant based on three series Rankine cycles combined with a direct expander using LNG cold as heat sink

“…Also, in Querol et al [6], a study of the boil off gas in Spanish LNG terminals managed using re-condensers is carried out, where the electricity consumed by these terminals is bought on the Spanish wholesale market. Furthermore, several power generating options using current available equipment and assuring the availability of the current terminal process have been analysed thermo-economically with acceptable results.…”

Thermodynamic analysis of direct expansion configurations for electricity production by LNG cold energy recovery

“…[13,14] the proposed combined system consists of the Rankine cycle with ammoniaewater mixture as working fluids [15]; presents a novel power plant consisting of a combination of a closed Brayton cycle with a steam Rankine cycle, arranged in series, while in Ref. [16] a combined cycle using a gas turbine and a pure NH 3 Rankine cycle coupled with the natural gas vaporization process has been chosen as the most advisable one to be installed. Different thermodynamic systems like those based on Stirling cycle and Kalina cycle have been proposed, but in general those can be considered only preliminary studies and non-commercial solutions, as argued in Refs.…”
