Sulphonation plant waste heat recovery processes leverage highly exothermic sulfur burning and
generation to produce high-pressure steam and hot water, often making plants energy self-sufficient. Key methods involve using waste heat boilers, heat-pipe exchangers 1, and economizers to capture heat, reducing external energy needs and maximizing efficiency 3.
