Those who are familiar with Davy’s anhydride process for BDO production, please come forward! !
Thread Content
I am working on a paper and would like to know what the steam consumption is in DAVY’s process of producing BDO through the esterification and hydrogenation of maleic anhydride t/t ； What is the pressure rating of the steam used? What are the other costs in Mpa, such as catalysts, hydrogen, N2, etc.? It’s fine if you know some or all of it; let me know if it’s convenient for you. Thank you so much! ! ! Thank you! !
Please, I hope experts can give me some guidance! ! !
It seems like all the experts are hiding; doesn’t anyone know about it? There are so many BDO factories in China
There are many BDO plants in China that use the Mark process developed by DPT, with capacities ranging from 10,000/30,000/55,000 to 75,000 units per year. Most of the information available online is general in nature; specific details regarding energy consumption, material usage, and catalyst consumption remain trade secrets, as no one dares to disclose them. With these, the cost of the final product becomes clear.
4# dychem Haha, what the big bro said is right. However, if there are experts in this field, it shouldn’t be considered a core secret to reveal the steam pressure level used in the DAVY process. Brothers who know about this, please give me some advice. Not very grateful! ! !
These are all trade secrets; even those who know them wouldn’t dare to reveal them
Our factory’s acetylene-aldehyde method is currently in the trial operation phase.
I’m keeping an eye on this; it’s quite difficult to find information on these things. I also have a question for the original poster: the maleic anhydride esterization solution contains a small amount of MDMS. What is this component?
The steam pressure used for each part is different; which part do you actually want?
MDMS Dimethyl Methoxysuccinate
Which section’s steam pressure do you need?
