Witryna2.2 Design of Refrigeration System Utilizing LNG Cold Energy To utilize LNG cold energy, an indirect refrigeration system using brine refrigerant was used in this study. Figure 2 shows a schematic of the proposed indirect refrigeration system utilizing LNG cold energy. LNG was pumped using a low -pressure pump located inside the LNG tank. WitrynaMuhammad Shariq Khan. The liquefaction of natural gas (NG) in a mixed refrigerant (MR) system is an energy-demanding process. Much energy is wasted because of its irreversibilities and its nonoptimal execution. …
