Synthetic Ammonia Process Technology Exchange Area [Daily Question 2009-03-17] How do you allocate the time for various stages in a UGI gas generation furnace? How should steam, nitrogen-enriched air, and recycling be set up? This post was last edited by *aoye613 on 2009-3-17 09:07.]
Our cycle lasts 135 seconds, as follows: blowing air, gas recovery, upper blowing, lower blowing, second upper blowing, final blowing to achieve cleanliness. 135 seconds – gas flow upward, then downward; temperature in °C: 28, 6, 32, 57, 8, 4; pressures: 200, 190, 230. No nitrogen is used during either the upper or lower blowing processes; the hydrogen-to-nitrogen ratio is adjusted by using the recovered blowing air, and control is quite good. Note that this is a hydroformylation process.
Thank you, I’m looking for indicators. Get yours down, hehe
