Regarding the sulfide levels in the wastewater from the bottom of the methanol-water separation tower in low-methanol processes
Thread Content
I would like to ask the experts in low-temperature methanol washing: has anyone paid attention to analyzing the sulfur compound content at the bottom of the methanol-water separation tower in such processes? We use a four-nozzle gasification process along with sulfur-resistant shift technology, and it’s the low-temperature methanol washing process developed by Dalian University of Technology. The sulfur compound level in the wastewater at the bottom of the methanol-water separation tower, as determined through analysis, is 14.6 mg/l. What is your own sulfide level? What is the source of sulfides? And the main components of sulfides?
We do not handle sulfides; we only deal with pH and the methanol content in wastewater. Linde process
For the carpentry process, we only analyze COD and pH; sulfides are not analyzed.
