  • Top Five Fundamental Integrity Issues for SRU Waste Heat ...

    2019-8-26 · Steam tempering is more commonly used because an SRU typically has an excess of steam available. Steam also has an added advantage in that the heat capacity is roughly double that of nitrogen and therefore takes half the mass flow to achieve the same tempering effect. Steam also will condense at the Quench Column and not add load to the downstream
