During the operation of CO2 compressor in urea plant,the insufficient separating capability of the separator caused the low pressure cylinder erosion and corrosion at level 3 and 4.Comparing the advantages and disadvantages of several repair plans,such as weld,slot positioning and inlay,utilization of metal repair compound,and laser cladding,finally the laser cladding repair plan was selected to repair the cylinder successfully.After the repair,erosion and corrosion didn't happen again,and the compressor was operated under good condition.
