Waste Heat Boiler. Exiting the WHB, the cooled stream achieves the first condenser where its temperature lowers to 180°C. After each catalytic reactor (two or three, depending on the SRU layout) there is a sulfur condenser operating at about 160°C. In these unit operations, low pressure (LP) steam is produced (3 to 10 bar).
