What is the appropriate pressure setting for sulfur-resistant wide-temperature conversion and heating?
Changing vulcanization temperature rise emphasizes large airspeed and low pressure to ensure bed penetration. The pressure must be less than 0.5kg. If you need other information, please contact me.
Pressure is controlled at 0.4-0.5MPa
We are circulating nitrogen to heat up. The safety valve setting value of the circulating fan is 0.72MPa. The pressure during all temperature rises is generally set to no higher than 0.5MPa!
If it is the original temperature rise vulcanization, it should be carried out strictly in accordance with the vulcanization plan set by the catalyst manufacturer. Different catalysts have different temperature rise vulcanization plans. Only low space speeds should be used for the original temperature rise vulcanization to ensure the penetration of the catalyst bed. If the temperature rise after long-term shutdown after vulcanization is completed, as long as the electric furnace is large enough, a larger air speed can be used to quickly heat up.
