Effects of stage number of condensing process on the power generation systems for LNG cold energy recovery

Thermal Energy Processes in Direct Steam Generation Solar Systems: Boiling, Condensation and Energy Storage – A Review

“…The results showed that the thermal efficiency, net power output, and energy efficiency of the new proposed cycle increased by 42.9, 45.3, and 52.3%, respectively. Bao et al (2017a) extended their work by examining the number of condensation stages for seven different cycles in power-generation systems for liquefied natural gas cold energy recovery. They considered three main parameters of electricity in their study: production cost, net power output and annual net income.…”

Organic Rankine Cycle for Recovery of Liquefied Natural Gas (LNG) Cold Energy

“…The electricity prices of literatures are different, such as 0.04, 0.061, 0.1, 0.123 and 0.18$/kWh [28]. DC and CC systems should be selected at the LNG vaporization pressure less than 30 bar if the electricity price is 0.04$/kWh.…”

“…For system structure, the combinations of simple Rankine cycle in series or parallel is often considered by Zhang et al [7] and García et al [15] and they found that they were indeed more efficient. Cascaded Rankine cycles are also common improvement and are proved to be superior to simple Rankine cycles by Li et al [16], Choi et al [17], Cao et al [18], and Wang et al [19]. By combining the Rankine cycle and refrigeration cycle, the study of Zhang et al [20] showed that both electricity and refrigeration can be produced simultaneously.…”

Review on recent liquefied natural gas cold energy utilization in power generation cycles

“…Based on this study, Bao et al studied the effect of the number of LNG condensing stages on the efficiency of cold energy recovery (Bao et al, 2017). In their study, seven systems, including direct expansion cycle, organic Rankine cycle (ORC), combined cycle, and four different multi-stage cycles (two-stage organic Rankine cycle, three-stage organic Rankine cycle, two-stage combined cycle, three-stage combined cycle) were studied.…”

“…The cold energy of LNG can be applied to all the processes that need cold, such as power generation (Oshima et al, 1978;Griepentrog et al, 2008;Shi et al, 2009;Shi et al, 2010;Liu et al, 2012;Song et al, 2012;Choi et al, 2013;Dong et al, 2013;Rao et al, 2013;Wang et al, 2013;Zhang et al, 2013;Arsalis et al, 2014;Gmez et al, 2014;Shu et al, 2014;Franco et al, 2015;Stradioto et al, 2015;Gmez et al, 2016;Sung et al, 2016;Bao et al, 2017;Ghaebi et al, 2018), cryogenic air separation (Bian et al, 2011;Xu et al, 2013;Xu et al, 2014;Mehrpooya et al, 2015;Zheng et al, 2015;Mehrpooya et al, 2016;Tesch et al, 2016;Ebrahimi et al, 2017;, seawater desalination (Cravalho et al, 1977;Shaik et al, 2006;Wang et al, 2012;Cao et al, 2015;Chang et al, 2016;Cherchi et al, 2017;Lin et al, 2017), cold storage (Messineo et al, 2008;Messineo et al, 2011), refrigeration (Mehmet, 2002;Kalinowski et al, 2009;He et al, 2015;…”
