Benchmarking chlor-alkali consumption: learn together, improve together
Thread Content
To all chlor-alkali companies: Subject: Benchmarking of chlor-alkali consumption – let’s learn together and improve together. We hope that each company will share its relevant data in order to enhance its own performance as well as the competitiveness of the industry. Electrolyzer model, year of installation, and specific energy consumption: NBH-2.7 (Beihua Machinery), October 2010. Direct current energy consumption: 2180 (10KA) KWH/t per 100 kg of caustic soda; motor energy consumption: 560 (10KA) KWH/t per 100 kg of caustic soda. Desalinated water required: 2.5 t/t per 100 kg of caustic soda. Salt, acid (31%): 100 Kg/t per 100 kg of caustic soda. Caustic soda (32%): 100 Kg/t per 100 kg of caustic soda
Since its operation began in October 2010, the direct current power consumption has been only 2180 Kwh per ton of caustic soda produced, indicating excellent control over the entire system. study*
Everyone, please share your own consumption figures as well; let’s help each other improve
Electrolyte power consumption: 2300 (NCHZ); date of activation: 2013.1 – this is too high
Is it an electrolyzer from Beihua Machinery? Is 2300 the power consumption at a current of 12 KA? What about other types of consumption? What are the costs related to power usage, acid used internally, alkali used internally, raw salt, desalinated water, and steam consumption? Learn from each other by setting benchmarks*. . . . . .
This post was last edited by aldd7611 on 2015-10-15 at 14:53. Is the cell voltage around 2.95V when the chlor-alkali plant of your company is operating at a current of 10KA?
I didn’t see it clearly before; this way isn’t actually accurate. The calculation methods for each chlor-alkali plant are generally similar, though there are some differences; the DC power consumption mentioned by the original poster probably does not include the losses associated with transformers, right?
Yes, what are your company’s consumption levels for various items? Do you have data on industry-leading consumption levels that you could share?
What is your organization’s consumption level? Could you share it?
Is it the power consumption of 12 KA current? What about other types of consumption?
