“…Thus, the heat input is less than ¼ of the total heat generated in the proposed thermodynamic LNG regasification cycle. The use of secondary low-temperature heat sources as a hot heat source (cooling water or engine exhaust gases) will significantly reduce the cost of the LNG regasification process and increase the capacity and efficiency of the thermodynamic regasification cycle of all liquefied gases transported by sea [16][17][18]. Lrt us Calculate the theoretical mechanical capacity of a conditional terminal with a capacity of 1.0 billion nm 3 /year equipped with a device manufactured in accordance with the proposed thermodynamic regasification cycle.…”

Comprehensive Thermodynamic Performance Evaluation of Various Gas Liquefaction Cycles for Cryogenic Energy Storage

“…Cooled air expands in a Joule-Thompson (J-T) valve, resulting in a two-phase fluid (4)(5). Liquefied air ( 8) is separated and stored, and the gas portion of the mixture (7) is sent back to the system. In real applications, no process can be completely isentropic.…”

“…where m comp is the mass flow rate of the gas; T 0 is the ambient temperature; s lq and h lq are the specific entropy and enthalpy of the liquefied gas, respectively; and s 0 and h 0 are the specific entropy and enthalpy of the gas, respectively, at ambient conditions. As all the gas entering the compressor is liquefied, the cooling effect (Q lq ) could be expressed as given in Equation (7).…”

“…Cryogenic fluids can be kept for many months in low-pressure insulated storage tanks with minimum loss [3]. There is a comprehensive application of cryogenic technology, including the liquefaction of various industrial gases, such as nitrogen [4], oxygen [5], helium, hydrogen [6], natural gas [7], etc. Liquefied natural gas (LNG) has gained popularity in the energy sector as a means of storing natural gas on a large scale and transporting it hundreds of miles from the locations of production to cities and nations [8,9].…”

Cryogenic Process Optimization for Natural Gas Purification: Predictive Modeling of Methane–CO2 Solid–Vapor Phase Equilibrium Using Response Surface Methodology

“…Cryogenic could be the first choice due to its advantages, i.e., it is environmentally friendly, has physical separation without any harmful solvents, and is applicable for a large range of compositions of natural gas with CO 2 . , However, many challenges still exist because it requires a substantial cooling duty . Achieving the low temperatures necessary for efficient phase separation requires significant energy requirements, often leading to an expensive process.…”
