What is the purpose of gas injection in the debutanizer tower?
It should be nitrogen injection to maintain the pressure balance at the top of the tower.
Does the poster mean to inject stripping steam at the bottom of the tower? The main purposes of injecting steam at the bottom of the tower are: Heating the bottom of the tower makes the light components gasify so that the components below carbon four can ascend (the temperature of this steam is generally around 365 degrees) ； Hydrogen sulfide can also be released ； The corrosion of subsequent products also has a lot to do with this!
Which device is it? The meaning of the question is unclear
The poster is talking about the hydrocracking unit. The injection should be stripping steam. Its function is to strip out the light components in the oil and the hydrogen sulfide in the product, so as to achieve the purpose of passing the corrosion of the product.
Thank you, your explanation is very clear.
Does the bottom of the debutanizer need to be injected with steam? Reboiler heating is generally used, and steam stripping has not been heard of. The top temperature of the debutanizer tower is generally about 70 degrees and the pressure is 1.2MPA. Under these conditions, the steam has already turned into water.
The steam stripper should be a hydrogen sulfide stripper, followed by a stable absorption process. The debutanizer does not require steam injection!
Study hard* , Make progress every day! :lol
Can steam stripping be used to strip the debutane and hydrogen sulfide from the top of the stripping tower during naphtha hydrogenation?
