into boiler feed water Steam generating boilers are com-monly used in sulfuric acid plants, for process gas cooling, waste heat recovery and steam usage at various locations. The steam—typically in the 450 to 900 psig range—drives turbines, and upon pres-sure reduction meets other heating needs in the plant. Upon extracting the usefulLearn More
Mar 30, 2020 · In this circumstance, the sulfuric acid production is an exothermic process (Aroussy et al. 2016a), in which the heat is recovered from absorption process of sulfuric acid by heat recovery system (HRS), with negligible temperature losses and minimum space requirements. The heat recovered is used for district heating of cities, boiler feed water Learn More
