“…Suna et al [13] proposed a novel Rankine power cycle which uses a mixture of hydrocarbons to recover the cold energy from LNG, and they found that the ethylene is more suitable than ethane to be used in the mixed working fluid. Kim et al [14] proposed binary mixture working fluid cascade ORC utilizing LNG cold energy, and the optimum working fluid and process configuration are obtained via an optimization. Cui [15] established a five-level Rankine cycle that uses the cold energy of LNG to generate power.…”

The topic of this study is the intermediate fluid vaporizer gasification system for a liquefied natural gas floating storage regasification unit. To reduce the loss of heat exchange, the primary distributary cascade three-level Rankine cycle is optimised based on the cascade three-level Rankine cycle that uses the cold energy of liquefied natural gas to generate power. The optimized primary distributary cascade three-level Rankine cycle is then compared with the original cascade three Rankine cycle established under the same conditions. Then, a secondary distributary cascade three-level Rankine cycle is proposed. Results show that under a liquefied natural gas flow of 175 t/h, the primary distributary cascade three-level Rankine cycle system exhibits a maximum net output power of 4130.72 kW and an exergy efficiency of 23.78%, which is higher than that of the typical cascade three-level Rankine cycle. Moreover, the net output power and exergy efficiency of the primary distributary cascade three-level Rankine cycle system increased by 3.71% and by 3.84%, respectively. The secondary distributary cascade three-level Rankine cycle system exhibits a maximum net output power of 4143.75 kW and an exergy efficiency of 23.85%.

“…With R601-R23-R14 ternary mixture as the working fluid, Lee et al [25] found that the exergy loss of ORC using mixture is lower than that of pure fluids. Kim et al [26] selected R14-propane mixture as the working fluids for the first stage of a cascaded system and ethane-n-pentane mixture for the other two stages. Modi and Haglind [27] thought that zeotropic mixture is the development direction of working fluids with its higher thermodynamic performance.…”

Organic Rankine Cycle Technology for Heat Recovery

Natural gas (NG) is an environment-friendly energy source. NG is of gas state in the environmental condition and it is liquefied to LNG at temperature of about −162°C for transportation and storage. Electric energy of 292-958 kWh is consumed when one ton of LNG is produced. Before being used, LNG must be regasified to NG again at the receiving site, and this process will release a great deal of energy, which is called cold energy. It's very important to recovery LNG cold energy, which is clean and of high quality.Power generation is a conventional and effective way to utilize LNG cold energy. For the low efficiency of the traditional power generation system with liquefied natural gas (LNG) cold energy utilization, by improving the heat transfer characteristic between the working fluid and LNG, this chapter has proposed a conception of multi-stage condensation Rankine cycle system. Furthermore, the performance of power generation systems will be enhanced with two aspects: improvement of system configuration and optimization of working fluids.

“…Innovative methods used in the Rankine cycle such as combining with a stand-alone refrigeration system seems to be a feasible option for exploiting thermal energy in places where electricity supply is unreliable 29 . It was observed that the application of waterfalls in a Rankine cycle is an option to improve the performance of this product [30][31][32][33][34] .…”

In this article, a bibliometric study was carried out on the research presented in the last decade on the Rankine cycle for the generation of energy through a gas-based power cycle. Tools such as HistCite were used to manage metadata, which included data such as authors' names, titles, abstracts, publication dates, document types, addresses and references cited. These data were analyzed and found results such as the significant increase in authors from 24 in the first year to a total of 438 in the last year. Another important outcome to mention is the country most cited in the study period. China with a total of 5887 citations led this measurement, thus achieving results to make visible the behavior of the studies conducted to the Rankine cycle.
