What is the steam pressure required in a reboiler for hydrochloric acid desorption? What is the temperature of the desorption tower? What are the actual pressure and temperature of the exported hydrogen chloride gas (after cooling)? Urgent! Urgent! Urgent! I know the steam pressure is approximately 18 kilograms, the reaction temperature is 260–280 degrees Celsius, and the outlet temperature is 120 degrees Celsius. What is the outlet pressure? I’m not sure if these numbers are correct Give me an answer, thank you very much! hcbbs !! .
It depends on what hydrogen chloride pressure you need What is it used for? Generally, the hydrogen chloride pressure is 0.2–0.3 MPa, and the temperature at the bottom of the tower is around 160 degrees. A steam pressure of around 0.8–1.0 MPa is sufficient.
I’m using this hydrogen chloride for a dehydrogenation compressor; so what is the exact outlet pressure required? Send it to the compressor manufacturer for design
When it comes to compressors, there are no specific requirements regarding pressure; any pressure level that can be generated can be transmitted, with even several tens of kilopascals being acceptable.
Reply to 4# lichsh1985: Is multi-stage cooling to room temperature required? Will the hydrogen chloride compressor not be able to operate properly at high temperatures? Do you have experience in this area?
Reply to 5# baoliang311: Under normal circumstances, compressors have certain requirements regarding the temperature of the inlet gas in order to utilize the compression process. However, the main purpose of cooling hydrogen chloride gas before it enters the compressor, as I have seen, is to remove water from the hydrogen chloride; in some cases, water at -35°C is used directly for this cooling and dehydration process.
Support for the first floor! That’s absolutely correct; it seems they have practical experience! Others in the same field can take this as a reference!
