I have a simple question about atmospheric and vacuum distillation; it’s urgent! ! !
Thread Content
I need to write a report on atmospheric and vacuum distillation, but I don’t know much about it; so I’ve looked for relevant materials to help with writing it! I’m seeking help from everyone. I saw a screw compressor in the atmospheric and vacuum distillation production workshop; the nameplate indicates that the medium used is reduced-pressure gas. I would like to know where this gas goes after it has been pressurized Some sources state that in the process of removing non-condensable gases, the gas is pressurized using a jet device, then condensed, and the resulting non-condensable gas is sent to a heating furnace for combustion. Is it the same with this screw compressor? My apologies
The processes vary depending on the device. Most reduced overhead gas is removed by steam stripping, then condensed and burned in a furnace. This mainly applies to low-sulfur crude oils; in such cases, the vent gas contains less hydrogen sulfide and can be burned directly. For sulfur-containing and high-sulfur crude oils, the top gas cannot be burned directly and requires desulfurization treatment. At this point, a compressor may be needed; the gas can be pressurized using a compressor and then sent to the desulfurization unit before being integrated into the gas pipeline network. Desulfurization can also be carried out directly, but due to the low pressure, a specialized desulfurization tower is required, and it cannot be integrated into the gas pipeline network.
