Ammonia Plant reformer case study for improvements of furnace conditions to achieve long tube life services

This paper describes the practical adjustments of primary reformer furnace for optimum operating conditions in Khorasan Petrochemical Co to achieve a reformer actual performance for continuity in production and decreasing the maintenance costs. Meanwhile the tubes are designed for high temperature and pressure resistance but the service life of tubes is directly depend on furnace conditions and tube wall temperature. Reformers may have different conditions based on capacity, environmental situations and feed compositions, but in addition to generic solutions each plant should be considered as a case study.
