Several issues in methanol reduction
Thread Content
1. What is the space velocity per cubic meter of catalyst during low-hydrogen reduction? During low-hydrogen reduction, the catalyst releases moisture; what I mainly want to know is what the optimal space velocity and flow rate are in order to carry away this moisture from the synthesis tower. 2. What is the safe gas flow rate for turning on the electric heater at startup? To turn on the electric heater, gas needs to flow through it; I’m wondering what flow rate is required to do that. I’m not aware of the model number for ours. Those with experience could share what they know about this. Finally, I hope experienced technicians can help answer this question – thank you in advance
The space-time velocity requirements for low-hydrogen reduction should be asked to the manufacturer who supplies the catalyst, as it is related to the usage requirements of the catalyst Is it also related to your loading capacity? You also didn’t specify which catalyst you used (Nanhua, Southwest Research Institute, or other imported manufacturers). The system pressure during our synthesis process was maintained between 0.6 and 0.8 MPa, with a flow rate of 6,000 to 8,000 Nm3. The second question isn’t very clear either; is it to prevent gas explosions? The key issue is not knowing where your electric heater is installed
The original poster’s question is indeed difficult to answer. Are you new to working in the chemical industry? There is no fixed value for the temperature-rise reduction space velocity; it varies depending on the type of catalyst, its level of activity, and the reducing agent used (hydrogen content). Generally, catalyst manufacturers develop specific plans for temperature-rise reduction, and these manufacturers have specialized engineers who can provide guidance. If one has questions, they can consult these engineers and learn a great deal from them
