Sulphonation plant reaction heat recovery units (WHRU) optimize efficiency by capturing exothermic heat from sulphur burning,
conversion, and
absorption to produce low-to-medium pressure steam (0.4–0.5 Mpa) or hot water. These units, often using fire-tube heat exchangers, can reduce or eliminate external steam reliance.
This video explains the initial step of a sulphur recovery unit:
