Regarding the problem with the demister at the outlet of the C-1701 stripping tower, what are the advantages and disadvantages of keeping it or removing it? Hope to have a constructive discussion (preliminary water treatment for extreme SHELL)
Why remove the defoamer screen? To reduce resistance? Or is it foam removal and scaling in NetEase? If scaling is likely to occur, the amount of regeneration steam should be increased, which in turn increases the amount of make-up water. After being washed through three layers of packing, it should become relatively clean, thus effectively preventing scaling.
Previously, a DESIGN of this type was used, with the aim of controlling the amount of water in the gas at the top. However, in actual production it was found that this mesh tended to get clogged; although a flushing mechanism was previously designed for this purpose, its effectiveness was likely poor. This is based on experience gained from nitrogen processing. Recently, this screen has been removed from the DESIGN of SHELL. In my opinion, proper heat tracing in this area, along with maintaining the slope and length of the tank V-1703 used for top recovery, renders the use of mesh screens unnecessary. Because in the end, it still has to pass through V-1703 before going outside the boundary. Of course, it’s better if there is a screen and no scaling occurs.
