What are the highest allowable levels for hydrogen, oxygen, and hydrogen sulfide in the gas compressed by the gas holder gas compressor?
Thread Content
Are there any requirements for the maximum levels of hydrogen, oxygen, and hydrogen sulfide in the gas compressed by the gas holder gas compressor? Especially hydrogen and oxygen; high concentrations can pose a risk of explosion. Operating condition: Compressor outlet pressure: 0.25 MPa. Exit temperature: around 95 degrees. Under these operating conditions, the hydrogen content in the gas is around 50%, while the oxygen content is around 2%. Is this situation dangerous? So, I would like to ask the experts: what are the maximum allowable levels for hydrogen, oxygen, and hydrogen sulfide in the gas compressed by compressors?
There must be people with knowledge in this field; let’s pull through! ! !
The hydrogen sulfide concentration in the gas holder for refinery off-gases at our company often exceeds 100,000 ppm. Such a high level of hydrogen sulfide poses a risk of corrosion to the steel structure of the gas holder as well as to the rubber seals, thereby creating safety hazards. What are the typical parameters for the inlet gas to refinery gas holders? For example, what the maximum hydrogen sulfide content should be, and so on.
The refinery gas holder seems to be a waste gas recovery station for various units, with unstable gas composition.
Pay attention to the oxygen content; too much of it can cause severe salt buildup in the compressors used for gas tank recovery
