摘要： A process of thermal fluid reclamation includes combining at least two recovered thermal fluids including at least two refrigerant compounds to form a consolidated thermal fluid. The consolidated thermal fluid is a blend of the at least two refrigerant compounds having a consolidated composition different from a recovered composition of at least one of the least two recovered thermal fluids. The process also includes testing the consolidated thermal fluid and validating that the consolidated thermal fluid has greater than 95 wt % organic purity. The process further includes adding at least one virgin thermal fluid or used thermal fluid to the consolidated thermal fluid to form a reconstituted thermal fluid. The process yet further includes analyzing and purifying the reconstituted thermal fluid to form a reclaimed thermal fluid. The reclaimed thermal fluid has a predetermined reclaimed thermal fluid composition different from a consolidated thermal fluid composition of the consolidated thermal fluid.

摘要： Methods and systems for liquefying natural gas using environmentally-friendly low combustibility refrigerants are provided. Methods of liquefaction include cooling a fluid in an LNG facility via indirect heat exchange with an environmentally-friendly low combustibility refrigerants that are propane, ethane and methane mixed with small amounts of fluorinated olefin, but still within close proximity to the boiling points of the pure refrigerants such that the mixed refrigerants can still be used in an optimized cascade process.
