Abstract:The revamping 40 kt/a sulfuric acid system based on pyrite conversion, and employing hollow ring type shell and tube heat exchanger are introduced. The new type heat exchanger results in increasing heat transfer coefficient, decreasing heat transfer area from 2345 m2 to 1279 m2, saving equipment investment of about 330 k RMB Yuan, lowering pressure loss from 15. 8 kPa to 8. 13 kPa and reducing energy consumption of 352 k RMB Yuan year.
Keywords:new type heat exchanger  sulfuric acid  revamping
