What parameters are measured for lean methanol in low-temperature methanol washing, and what are the specific values?
The methanol-poor indicators we are testing now include: 1. Water content； 2. Total sulfur content ； In addition to these routine analyses, it is recommended to test for ammonia levels ；
1. Water content <1% 2. Total sulfur <1ppm 3. Ammonia <1ppm 4. HCN <1ppm 5. pH 8---9
It makes sense to measure ammonia levels; but what’s the purpose of measuring HCN and pH as well?

We only test for methanol purity (97% or higher is sufficient), and the total sulfur level can be below 100 mg/L.
Why is it necessary to measure the methanol concentration?
