What are the differences in the setup of restructured units?
Thread Content
There are two configurations for the reforming unit: In one configuration, the hydrogen produced in the reforming product separation tank is fed into the recycle hydrogen compressor. After being pressurized, this hydrogen is sent either to mix with the reforming feedstock in the reactor or to the inlet of the booster compressor (for secondary compression)； Secondly, the hydrogen produced in the reformation product separation tank is divided into two streams: one stream goes to the recycle hydrogen compressor, and the other goes to the booster (three-stage compression). Which of these two process settings is better?
I’m hearing this from the original poster for the first time regarding the first type. I don’t know what the pressure at the secondary inlet is. The outlet pressure of the cycle hydrogen compressor must be higher than the inlet pressure of the second stage; liquid separation is required first, and the selection of the booster and the cycle hydrogen compressor is also an issue. I don’t understand this process; what kind of process and technology is it? If it’s convenient for the poster, could they upload the PFD and crew information?
Reply to 2# che7420: There is a liquid separation tank. There are many such processes; basically, all new reorganization projects these days follow this process.
It involves the selection and configuration of compressors. The first approach uses one booster unit to drive two compressors, which facilitates the arrangement and maintenance of the compressors; however, the cycle hydrogen compressor becomes larger as a result. The second option facilitates the selection of compressors, but with a booster driving three units, it is not conducive to layout and maintenance.
