Method for recovering sulfuric acid from sulfurous by-products of a process for preparing 2-hydroxy-4-methylthiobutyric acid (mha) |
| abstract |
The invention relates to a method for recovering sulfuric acid from sulfurous by-products which arise in processes for preparing 2-hydroxy-4-methylthiobutyric acid (MRA), wherein the sulfuric acid accumulates in a grade in which it can be directly reused in such processes. For this purpose the combustion gas containing SO2 is passed through a sulfuric H2O2 solution in which the SO2 is oxidised to form sulfuric acid. |
