The formaldehyde production plant is about to start operating, and there are some issues that are not clear yet; I would like to ask my friends for advice: 1. When starting up the plant for formaldehyde production, how should the feed flow rates of methanol and air be controlled, and what are the appropriate range values for these controls? 2. How much methanol vapor can each volume of air carry away? 3. How to control the oxygen-alcohol ratio? 4. How can the equilibrium concentration of methanol be monitored in real time? 5. For an annual production of 50,000 tons of formaldehyde, what is an appropriate temperature for controlling evaporation? 6. What is the impact of the steam volume used in feeding on the explosion range? 7. What should be the appropriate range for the steam used in ingredient preparation?
