Cost issues of lithium bromide technology
Thread Content
Using lithium bromide technology for semi-water gas seems like a good idea. But it’s not clear whether the costs are high or not, and whether it’s worth it. Has anyone done a cost estimate?
It depends on the required cooling capacity; if the water flow rate needed is between 500 and 1000 m3/h, the investment cost will be between 1.5 and 5 million yuan. Of course, costs vary depending on the heat source and the type of equipment used.
Investment estimate for 3423.45KW bromine-cooled units: 1 unit of the 349D type bromine-cooled unit costs 1.9 million; two gas coolers cost 650,000 for a new system and 550,000 for an old system; electrical equipment and instruments cost 250,000; desalination tanks and civil works cost 200,000; two cooling water pumps cost 80,000; three circulation water pumps cost 150,000; two cooling towers cost 500,000; anti-corrosion and insulation measures cost 300,000; pipes, fittings, valves and installation costs amount to 600,000; chemical dosing equipment costs 20,000; and unforeseen expenses total 200,000. The total cost comes to 5.2 million. The operating costs for these units are as follows: ① Operating cost per unit is calculated at 555KW/h; ② Cost of chemicals: 200 yuan per day; ③ Labor costs: ######; ④ Maintenance cost: 2,000 yuan per month × 12 = 24,000 yuan
If low-pressure steam is used as the heat source, it provides a better energy-saving effect compared to using hot water as the heat source. Because it can at least save the energy required to transport hot water, thus saving electricity. The specific cost has not been calculated, so it cannot be provided.
The hot water commonly used is usually waste heat water; using steam seems a bit wasteful, after all, the cost of steam is higher than that of waste heat water
Thank you to Classmate Xing Tiandaxia for the answer. The cost of this technology is quite high! Perhaps graphite cooling technology is a bit cheaper.
“I heard about the “graphite cooling technology” for the first time; I searched online, but there wasn’t much information available. Could the original poster please give some introduction so we can gain some insight? Thank you first!
Who knows about “graphite cooling technology”? Please give an introduction.
Range of usable low-pressure steam: 0.012~0.8 MPa; Hot water temperature: 75~140°C； Using the waste heat generated in the manufacturing process as the heat source for driving the lithium bromide chiller, and taking advantage of the properties of lithium bromide, cold water at temperatures above 7 degrees can be produced, thereby replacing traditional cooling methods and improving cooling efficiency.

Why must the temperature of hot water be above 75 degrees Celsius? Our factory currently has a large amount of hot water at around 70 degrees; I wonder if it can be used? Please give your advice
