Between October and December 2018, NIIK’s specialists performed repair works for relining of urea synthesis reactor R202 at Nitrogénmuvek Zrt. urea production plant (Pétfürdo, Hungary).
Urea production unit Pétfürdo II with a capacity of 600 tpd (Stamicarbon technology) has been operational since 1975. Since 2017, lining leakages have increased the number of unplanned shutdowns of the reactor. Nitrogénmuvek decided to involve NIIK's specialists for urea reactor rehabilitation.
Within the specified period, NIIK’s specialists developed repair technical documentation for manufacturing liner parts and expanding devices followed by technical assistance for the production thereof; performed a whole range of assembly and welding works for installing 32 liner belts including NDT of welding joints.
Upon Nitrogénmuvek’s request, NIIK carried out repairs of carbon steel shell and overflow pipe as well as performed corrosion inspection of the top and bottom parts of urea reactor, resulting in a report with the list of defects and recommendations for their elimination during the next plant turnaround. The plant started production in early January started and is currently fully operative.
