Abstract:
A system ( 100 ) for producing aqueous sulphuric acid. The system ( 100 ) comprises a first heat exchanger ( 410 ) configured to cool water and/or aqueous sulphuric for producing cooled water and/or cooled aqueous sulphuric acid; a pre-cooling unit ( 200 ) configured to pre-cool some gas containing sulphur trioxide, the pre-cooling unit ( 200 ) comprising an inlet or inlets ( 212, 214 ) for receiving [i] the gas containing sulphur trioxide and [ii] the cooled water and/or the cooled aqueous sulphuric acid, an outlet ( 216 ) for letting out aqueous sulphuric acid and the gas containing sulphur trioxide, and a first nozzle ( 220 ) for spraying the cooled water and/or the cooled aqueous sulphuric acid onto the gas containing sulphur trioxide to cool the gas containing sulphur trioxide. The system further comprises a condensation tower ( 300 ) comprising a first inlet ( 302 ) for receiving the cooled gas containing sulphur trioxide and aqueous sulphuric acid from the pre-cooling unit ( 200 ) and means ( 320 ) for circulating the aqueous sulphuric acid within the

Claim (Index 31):
A pre-cooling unit ( 200 ) suitable for cooling gas comprising sulphur trioxide from a temperature of at least 400\u00b0 C. to a temperature of at most 150\u00b0 C., the pre-cooling unit comprising:\n an outer wall ( 260 ) limiting a reaction chamber ( 202 ) of the pre-cooling unit ( 200 ), \n an inlet or inlets ( 212 ,  214 ) for receiving [i] the gas containing sulphur trioxide and [ii] cooled water and/or cooled aqueous sulphuric acid into the reaction chamber ( 202 ), \n a first nozzle ( 220 ) for spraying the cooled water and/or the cooled aqueous sulphuric acid onto the gas containing sulphur trioxide to cool the gas containing sulphur trioxide and to react some of the sulphur trioxide with some of the cooled water and/or cooled aqueous sulphuric acid, thereby strengthening or producing some aqueous sulphuric acid, \n a thermally insulating inner wall ( 256 ) surrounded by the outer wall ( 260 ) and surrounding the reaction chamber ( 202 ), \n a first inner wall ( 252 ) made of acid proof material, surrounded by the outer wall ( 260 ) and surrounding the reaction chamber ( 202 ), \n a sacrificial lid ( 240 ) that comprises metal ( 241 ) that is coated with a lining ( 244 ) that comprises plastic material, the plastic material being heat resistant to at least 230\u00b0 C. and facing the interior of the pre-cooling unit ( 200 ), and the sacrificial lid ( 240 ) being connected to the outer wall ( 260 ) with second openable fastening means ( 243 ), \n a cooling channel ( 248 ) that is arranged in contact with the sacrificial lid ( 240 ), \n an inlet ( 248 a ) for feeding coolant to the cooling channel ( 248 ), and \n an outlet ( 248 b ) for removing coolant from the cooling channel ( 248 ), \n wherein at least a part of the cooling channel ( 248 ) and at least some of the lining ( 244 ) are arranged on a same straight line (L) that is parallel to a surface normal (N) of the sacrificial lid ( 240 ).
