Location of the heating passivation pipeline in the CO2 stripping unit
Thread Content
Dear sea friends, I would appreciate your insights regarding the location of the heating and passivation pipelines in your factory, as well as the advantages and disadvantages of using such systems.
Friend: I’m not sure about anything else, but from what I’ve seen, steam and air are added to the CO2 feed pipeline leading to the stripping tower. The low-pressure pipes for steam and air are equipped with swivel joints that can be disconnected or blind flanges are installed, all for safety reasons.
Here too, it is on the pipeline where CO2 enters the stripping tower.
The steam and air lines used for temperature-induced passivation are connected to the CO2 line entering the stripping tower, with blind flanges placed between them. The blind flanges are removed before the temperature-induced passivation process, and reinstalled afterward.
What are the advantages of the design in our plant for the liquid outlet pipeline of the synthesis tower?
Do you use it in actual production?
We are building the facility; it hasn’t started operations yet! !
Yuntianhua Co., Ltd. has a steam and air pipeline in the liquid outlet pipeline of the synthesis tower; this pipeline is used to heat and preheat the synthesis tower before starting the compressor once the steam system is in place. For passivation, traditional carbon dioxide-air passivation is employed. Jin Xin has a steam pipeline in the liquid outlet pipeline of its synthesis tower, which is used for heating; Safurex material is used in this pipeline, and no passivation is required
Steam and air are added to the CO2 feed line of the stripping tower, as well as to the steam and air pipes on the downcomer of the synthesis tower on the 3rd floor. Temperature-induced passivation can occur in both of these places.
Which method is better? We have a new project and would like to know more
In our plant, the medium-pressure steam and instrument air used for heating are connected to the CO2 inlet pipeline, with blind flanges used to separate them
