Control of urea hydrolysis
Thread Content
The hydrolysis tower in our company’s urea production unit is vertical, with a diameter of 1800 mm and 24 trays. Its normal processing capacity is 31–35 m3/h. During operation, it is difficult to maintain a stable liquid level; even a slight change in operating conditions can easily lead to either an overfilled or underfilled condition. What happened next was that the upper part of the tower collapsed at the vapor phase temperature, and it was difficult to restore normal operation in a short time by methods such as maintaining a stable liquid level, increasing steam supply, or reducing load. I also checked a few similar devices and found the same issue; I would like to ask fellow users what the problem is!
Could you help me download the animation of the air separation process? https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1301024. My account level isn’t high enough; I need it for use during training in a few days. Thank you! Email: 646645133@qq.com
Most of the hydrolyzers produced by our company are of the horizontal type; it is likely that this is because the designed output does not meet the actual requirements Communicate more at 8027777@qq.com
