How to control the methanol production volume?
Thread Content
Recently, the production volume of the methanol unit in our factory has been very unstable! Before, it was only missing 2 or 3 tons! Now the difference is at most 13 tons! The main issue is the low output during the evening shift (4 p.m. to 12 a.m.)! (Three-shift system)! ! ! The output difference between the other two classes is not significant! Firstly, the gas volume, gas composition, and operational level are all basically stable! ! The refined methanol level in the tank area is also correct! Is it related to changes in temperature? Or something else,,,! ! I’m so frustrated! I’m seeking advice from the experts here! ! Kneel in worship. . . ! ! ! !
I don’t know what the output per shift is. Normally, high summer temperatures have a certain impact on methanol production, but since the daytime shifts experience the highest temperatures, the production should be the lowest; therefore, it can’t be the temperature that’s causing this effect. You say there’s no difference in volume, gas composition, or operational level; it’s just due to human factors.
Could you tell me your company name? It’s mainly the change in temperature. If it’s rainy, the yield difference won’t be so large.

1. Is the concentration of the gasified coal slurry lower than that of other teams? 2. Is the feed volume lower than that of other teams? 3. Is the methanol content in the distillation wastewater higher than that of other teams (as methanol is removed from there)? 4. The feed to the pressure tower and the atmospheric pressure tower should not be too low; sufficient steam supply is required
Reply to 6# *ao Bird: Is thermal expansion and contraction that significant? A cylindrical tank with a diameter of 6M! The liquid level difference is 20 centimeters! ! :Q I don’t believe it! !
