| titleOfInvention | Process for the preparation of sulfuric acid using hydrogen sulphide |
| abstract | Provided is a process for producing sulfuric acid using hydrogen sulfide. The method comprises the following steps: (1) performing a redox reaction between an H 2 S feed gas and oxygen contained in an oxygen-rich air to produce SO 2 , controlling the residual oxygen after the redox reaction step to a molar percentage of ≥ 2 %; (2) cooling the product obtained in step (1) to a temperature of 390 ° C and 430 ° C, and then performing a catalyzed oxidation reaction with oxygen, wherein the catalyzed oxidation reaction is carried out in stages until the conversion rate of SO 2 ≥ 98 Is 7% or the outlet concentration of SO 2 ≤ 550 mg / Nm 3 ; and (3) cooling the product obtained in step (2) to a temperature ≥ 10 ° C above the dew point temperature of H 2 SO 4 , then further cooling to a temperature of 60 ° C and 120 ° C, collecting the H 2 SO 4 Producing and subjecting the obtained after cooling gas coalescence separation before it is discharged directly into the atmosphere. Furthermore, there is provided a heat exchanger comprising a housing and a plurality of glass tubes, wherein the glass tubes are disposed within the housing along the longitudinal axis of the housing in the inside of the housing, and extend between two lateral walls, and used for the circulation of cooling medium; adjacent glass tubes are connected from head to tail to form at least one unidirectional flow path of the cooling medium. The process for the production of sulfuric acid provides a high efficiency for the removal of hydrogen sulfide, a simple process and an economical efficiency of the equipment and appropriate use of energy. |
