Is the torch tip frozen?
Thread Content
Our company operates aromatic units, and the flare head is a three-way steam flare head. There are also molecular seals. After the optimization, our company’s exhaust emissions are very low; in other words, the amount of flare gas is minimal, and there are no open flames. During design, the three-way steam was medium-pressure steam; later, it was modified to use low-pressure steam for Uppersteam. The problem we are facing in our company right now is that during the cold winters, a significant amount of icing occurs on our torch tips. Seek analysis from experts.
Pay attention!!!!!!!!
The main reason for freezing is the moisture and liquefied gas contained in the exhaust gas when the operating unit is stable. And liquefied gas absorbs a large amount of heat during vaporization, causing freezing
Could it be that since there’s hardly any open flame in our torches, the temperature at the top is relatively low?
Add some more fuel gas, otherwise it won’t meet environmental standards
By the time the low-pressure steam reaches the flare tip, it is mostly condensed water, with most of the heat being used for heat exchange with the pipelines； In the north, ice forms when it rains or snows; even in the absence of rain or snow, ice forms on the inner wall of the torch tip. Therefore, electric heating and insulation need to be provided on the outer wall of the torch head; otherwise, accidents can occur when there is a large amount of gas discharged from the torch.
Since there is no open flame burning, your torches are nothing but decorations; they fail to serve any purpose in protecting the environment. Moreover, the freezing of water at the tip of the torch poses a risk to the system – it’s likely that the material flowing ahead contains water, and the conversion of liquefied gas from a liquid to a gas state absorbs heat, causing the water to freeze. I wonder if there is a water separation tank at the front end of your torches?
