Heat Recovery from Hot Acid

Sulphuric acid plants have circulating acid streams in the absorption towers. These streams come out of the towers as hot acid. Low-pressure steam can be generated by recovering heat from such streams of hot acid. Readers may contact Monsanto Enviro-Chem, USA, for more information since it is their technology. 

Hot water production for process use from hot acid by use of plate heat exchangers with special alloy construction (with dual cooling circuits) has been carried out by the author.
