Some issues regarding material balance in methanol synthesis; seeking advice from experts
Thread Content
I have already calculated the amount of gas required for synthesis, as well as the flow rate and composition of the products formed, along with the flow rate and composition of the fresh gas fed into the reactor. It is known that the methanol content in the gas exiting the synthesis reactor is 2.8%, while the methanol content in the methanol recycle gas is 0.05%. How can I determine the composition of the methanol recycle gas? I can calculate the flow rate of the gas exiting the synthesis reactor and the flow rate of the methanol recycle gas. But I can’t determine the composition of the recirculated gas; I hope experts can offer some guidance. Thank you
I hope someone with more experience can give me some advice; I’m in a hurry~~~~~
The key issue for the poster is the conversion rate of CO and CO2, but the poster knows the conversion rate of C (based on the methanol content at the inlet). Solution: Pay attention to the water vapor shift reaction, which easily reaches equilibrium; by this, the conversion ratio of CO to CO2 can be calculated.
Do you produce methanol from coke oven gas? Is it by comparing theoretical calculations with analytical data?
I am working on a graduation project: the design of a synthesis process for producing 5WT methanol on an annual basis
The composition of the recycle gas has no essential relationship with what you mentioned above; the amount of recycle gas is related to the content of inert gases in the system. With an annual production of 50,000 tons, it’s only possible to calculate how much fresh gas you produce per hour; moreover, fresh gas comes in various compositions. And the system circulation rate can be controlled manually; of course, the composition will also change
I remember really wanting to reply to a post like this
Hehe, it’s not an illusion upstairs; I sent you a private message.
I work in the production of 600,000 tons of methanol; I only know the inlet flow rate of the fresh gas and the composition of its various components. I need to calculate the composition of the recycled gas as well as that of the methanol at the outlet. I hope those who are familiar with this process can help me out. Thank you!
