The urea reactor in Abu Qir 1 has been put in operation since July 1979.
After 20 years of operation, at August 1999, the first lining failure in the gas zone area was detected through the leak detection system. Successfully temporary repair was done, and the reactor was put in operation again after a 6 days shutdown. Operating with the temporary repair continued without problems. Organization for permanent repair started directly after the temporary repair. The permanent repair was carried out in September 2000 by Abu Qir team with the guidance of a Stamicarbon specialist.
