Catalytic cracking water integration
Thread Content
During the water commissioning phase when a newly built unit is put into operation, if water is supplied from the reflux tank at the top of the distillation tower and fed into the tower via the top reflux pump, will the water flow automatically into the side column? Also, does the side column participate in this water commissioning process? What is the process if I decide to participate? Thanks. This post was last edited by Shuichangshou on 2009-2-22 at 18:13.]
It will definitely flow into the side-line tower； To participate in water intermodal transport ； Proceed to No. 1 Middle School through the normal process.
If water is supplied from the reflux drum at the top of the distillation column, and the distillation column is fed with water via the top reflux pump, an excess amount of water will flow automatically into the side column； Another point is whether the side-line towers will be involved in water intermodal transport as part of extensive training exercises. Check out the process for participation; once you see what happens on site, you’ll understand everything.
I heard about the term \"side line tower\" for the first time. The so-called water transport system means that all equipment and pipelines need to be connected, just like in the normal process; of course, steam will also enter the stripping tower. Pay attention to details such as removing the orifice plate from the flow meter, replacing various filters with higher-quality ones, and using cross-wiring for the instruments.
A side line tower is presumably a tower used for side line purposes. From the structure of a distillation tower, water will flow automatically into the side line tower; wherever there is a side line outlet, water will flow out—provided that the side line tower is shorter than the distillation tower. If valves are used for control, that’s another matter. As for how the flow takes place, it depends on the actual process flow and piping arrangement on site.
During water interconnection, water is fed into the tower by the return pump at the top of the split tower, and it enters the side-line extraction port； When the unit is operated in water-cooled mode, all towers and systems must be involved, following the normal procedure.
Water commissioning of the newly installed unit is necessary. Generally, water needs to be circulated to the top; all process pipelines must be routed accordingly. The design of these pipelines varies from one unit to another, and the water circulation path is determined based on the process flow. In some cases, temporary pipelines are also required.
You mean the stripping tower, right? The water-cooled operation is the normal process; check for any leaks or spills, as well as pipeline flushing
