Separation of hydrogen and toluene
Thread Content
I would like to ask the experts: are there any membrane separation techniques used in industry to separate hydrogen from toluene, or are there any methods that can reduce the toluene content? Currently, environmental regulations are strict; the level of toluene in hydrogen exhaust gases is significantly above the allowed limits (the required level of toluene outside the plant is <2 ppm)
What industry? It is higher than the limit value of 0.8 mg/m3 for toluene in Table 7 of GB 31571-2015, the standards for pollutant emissions in the petrochemical industry! There are many methods for low-concentration treatment, right? Adsorption isn’t very effective; for high concentrations, the heat of combustion is utilized.
The hydrogen system in the plant cannot be introduced into the carbon bed for adsorption
What is your manufacturing process? How can toluene be present in hydrogen? What is the current level of toluene present? Do you still recycle hydrogen? Let me see if I can help you solve this problem
Is there any way to get in touch to discuss this in detail?
