Fertilizer plant. The cartridge is used to filter the iron mainly from piping. Previously the replacement of cartridge is done in six monthly basis. However after the recent shutdown, the dP increased to >1bar within 2 weeks. Actually big contribution from turbine condensate is 54% from the total condensate. In term of oxygen, the reading maintained below than 7ppb at the outlet of deaerator. If refer to surface condenser performance which maintained at the vacuum pressure and confirm no oxygen ingress into condensate system. Observed presence of methanol in the steam system due to tube leak at the methanol reactor and iron pick up which the result is higher than 0.02ppm.
