After searching through so much information, I couldn’t find any data on the energy and material consumption metrics of polycarbonate production processes! Whether it’s the phosgene-based method or non-phosgene methods, most of the papers available on VIP or the e-books on Chaoxing are based on copied content, and the information is already outdated.
Indeed, there are very few, and there are no clean production standards
There is a certain difference between the data in the paper and the actual situation. Because for some data, those who are aware of it do not have the authority to disclose it, especially when communicating with foreign parties, a confidentiality agreement is signed.
Raw Material Consumption Sequence Number Name and Specifications Unit Consumption per Ton of Product Annual Consumption Source 1 Raw Materials 1 Bisphenol A 104 t/a 0.89 Purchased 2 Sodium Hydroxide 104 t/a 0.6 3 Dichloromethane 104 t/a 4 Phosgene 104 t/a 0.5 5 Catalysts 104 t/a
To find out the figures for energy and material consumption indicators, you will likely need to turn to relevant design companies in order to get this information. After all, these are all confidential. It cannot be leaked.
Reply to 5# lg123333: Hello? Do you know? Specific utility consumption? Just an approximate amount is fine?
These are all confidential matters; I guess ordinary people don’t know about them
It’s all the truth; can I tell you then? ? ? ? ? ? ?
