Is the two-stage absorption and two-stage regeneration technology for sulfur recovery solvents a patent? Could those who are familiar with the sea please explain what’s going on exactly?
Save energy and reduce consumption. This is commonly used for large solvents, but not necessary for small ones
Haiyou, could you explain in more detail how to achieve energy savings and reduced consumption?
Two-stage absorption means two phases of absorption: semi-poor liquid is used in the middle part of the absorption tower, while pure poor liquid is used at the top. The semi-poor liquid comes from the middle part of the stripping tower, which reduces the amount of steam required. Therefore, this method is commonly used for large quantities of sulfur; plants built before 2005 rarely used it, as back then most sulfur handled was in small quantities of tens of thousands of tons each.
