Discussion on the Design Scheme of Low-grade Heat Recovery System of a Sulfuric Acid Plant
In order to support the upgrading project of the sulfuric acid plant in the"Shuang Shan"plant,a low-grade heat recovery system for waste heat power generation is added.After the system is put into operation,the comprehensive energy consumption by sulfuric acid is negative,the power gen-eration increases by 1.4×108 kW·h/a within half a year,and the carbon neutrality of the sulfuric acid production process is achieved,reducing carbon emissions by more than 90 kt/a,with significant energy saving and consumption reduction performance.
