| Abstract: | Aimed at the abnormal operation of HP scrubber in urea plant, analyzed the phenomena and reasons, and confirmed that it was caused by the packing crushing, severe scaling or the blocking of the liquid distributor holes at the packing top. Aqueous hydrogen peroxide system and temporary piping were used to recover LP carbamate ammonium into HP system, thus the problem of liquid entrainment in the vented tail gas from HP scrubber was effectively solved. |
