In producing urea by pril Method , which is produced by two reactions in high pressure and high temperature , urea synthesize reactor always has nonreactioned carbamat and nearly ammonia that their amount depend on input air combination . So , there are always five products in reactor out put such as , water , ammonium carbamat , urea , carbon deoxide and ammonia which the high corrosion function of ammonium carbamat under high pressure and temperature caused some problems in production and gradually demolishs the equipments. So , this project is planed and performed in order to do more scientific investigation and selection of suitable methods to prevent corrosion or finally decreases the production cost and increases the production efficiency.
