This process was developed by Linde Corporation in this century; it features three refrigeration cycles: a pre-cooling cycle, a liquefaction cycle, and a subcooling cycle. As shown in Figure 1-5, these three cycles allow for a more optimal matching of the heat flow and cold flow temperature curves in the heat exchangers compared to using a single or two mixed refrigerant cycles. This results in optimal efficiency and minimum energy consumption. By distributing the cooling load across these three cycles and three compressors, the production capacity per unit can be increased to 8–10 million tons per year. Meanwhile, C3/MRC or DMR requires 2 production lines to achieve this capacity. This process has been applied to the LNG project in Snohvi, northern Norway, with a plant capacity of 4.3 million tons per year.
