Evaluation of LMTD. The LMTD values of [20] are 26.47 C, 42 C, 40.98 C, and 38.61 C for AC1, two, 3, and four, respectively, and correspond for the output air temperature of 24.32 C, 25.83 C, 25.78 C, and 25.7 C. As the air flow ought to be heated inside the air cooler, the worth of 24.32 C is just not constant, since it need to be greater than 25 C. The boost in air temperature is extremely small, around 0.7 to 0.83 C in [20]. As a result, the volumetric flow of air and energy consumed is higher. The price of air coolers is area-dependent. The values of air volumetric flow price and area of [20] were not explicit. In the present Compound 48/80 Autophagy operate, the energy consumed and fees of air coolers (Table 4) are 0.679 kW, 1.120 kW, 1.081 kW, and 0.982 kW, and 11,884 US ; 14,550 US ; 14,537 US ; and 14,450 US , for AC 1, two, three, and four, respectively. The values of [20] for power are 7.64 kW, 7.63 kW, eight.05 kW, and 7.64 kW, and charges are 137,320 US ; 137,320 US ; 135,823; and 137,261 US for AC-1, two, 3 and four, respectively. The power consumed and expenses of air coolers applied herein usually are not related to [20], because of the diverse output air temperatures. Our lower air volumetric flow reduces the energy with the fan. The price of air coolers is based on location, and in accordance with [38], in 2002 the price of an air cooler with an area of 9.185.22 m2 (9864 ft2 ) was between 20,000 and 25,000 US . According to [29], the cost restatements of gear (expense index) needs to be used with caution when contemplating periods more than ten years and ought to not be applied to equipment. Technologies improvement and competition considerably have an effect on the cost. Inflation increases price tag while technological advances reduce the price. Hence, an air cooler price amongst 11,880 and 14,550 US is extra reasonable. The worth applied by [20] (137,000 US ) would correspond to an immense area of 44.83 kft2 (4164 m2 ). AC1 and 2 have different loads, having said that, they have precisely the same energy and cost. The precise charges of power from expander 1 and two are 305.20 US /GJ and 334.10 US /GJ, respectively. The average particular expense of power is 314.00 US /GJ. It truly is critical to note that the cost of the electricity supplied by the electric grid is four.72 US /GJ, which is reduce than the cost of energy developed. This occurs for the reason that the Nimbolide manufacturer purpose of the method is to liquefy all-natural gas and not to create electricity. It really is a sub-product that reduces the price of the liquefaction course of action. The product in the method can be a liquefied natural gas at point 35. Its precise price is 283.00 US /GJ. Point 39 is composed on the LNG cost rate of point 35 plus the reallocated fictitious expense price on the valve plus the cost rate of released nitrogen in the atmosphere at point 26, which yields a specific cost of 292.30 US /GJ at point 35. The price rate of air coolers is null for the input and output of environment air (air input at zero price). However, the output of air should have a cost rate, which is charged towards the compressors (the cost price of air cooler output, that is a dissipative component, was reallocated to the compressors).Energies 2021, 14,13 ofTable 6 shows the exergy destruction rate, exergy efficiency, average price per exergy unit of fuel and item, cost rate of element, exergoeconomic issue, and price relative distinction.Table six.
