Liquid sulfur measurement in sulfur recovery unit
Thread Content
Which type of level gauge is suitable for measuring the liquid level in a liquid sulfur tank? What are the advantages and disadvantages of using a blowout type level gauge? Seeking advice from experts
We all use blow-out type level gauges. I used radar level gauges before, and they often had problems.
Liquid sulfur tank – individually approved air-puff type liquid level gauge.
Radar crystals tend to form at the antenna, which affects measurements; after all, the temperature of liquid sulfur is relatively high
Level measurement is generally done by back-blowing nitrogen, based on the constant current principle.
We are now also facing the issue of choosing a suitable liquid sulfur tank, struggling between the blowing method and high-frequency radar. We don’t know exactly what the disadvantages of the blowing method are, nor what the advantages of radar are; we want to know which one is better and requires less maintenance.
We are also faced with the question of whether to use air or radar. Is air supply stable? Since interlocks are involved, there is always a concern about accidental operation that could result in steam being released.
