When the hydrogen sulfide content in acidic gases is between 15% and 50%, a split-flow process is used in sulfur recovery units. Why is the split-flow method used at this concentration? What are the advantages and disadvantages of this method?
There are still many defects; it may be necessary to use fuel gases such as gas to assist combustion in order to maintain the furnace temperature； At the same time, air distribution is also very difficult to adjust.
Oh! I’m sorry, I must have misread it; it’s the split-flow method, not the partial combustion method.
In the split-flow method, the reaction in the combustion furnace takes place according to 100% stoichiometry, right? No sulfur is produced, right?
The shunting method was first used in China’s sulfur industry at Qilu and Shengli refineries, as the blackening of sulfur occurs when some hydrocarbons are not burned.
