Fill-in-the-blank: The function of Tower T3004 is (). Thorough thermal regeneration of methanol is carried out to completely desorb H2S as well as CO2, thereby producing lean methanol and H2S-rich acid gas.
Getting the device tag number – it’s not easy
It is mainly about regenerating methanol, that is, reusing it. Methanol absorbs sulfur- and carbon-containing substances in the absorption tower, and at that time its temperature is quite low. After passing through the CO2 product tower and the H2S separation tower, the sulfur- and carbon-containing substances in the methanol-rich stream are removed, and then this stream enters the regeneration tower
Yes: Thorough thermal regeneration of methanol is carried out to completely desorb hydrogen sulfide and carbon dioxide, thereby producing lean methanol and hydrogen sulfide-rich acid gas.
Thorough thermal regeneration of methanol is carried out to completely desorb H2S and CO2, thereby producing methanol-poor gas and H2S-rich acidic gas.
Thorough thermal regeneration of methanol is carried out to completely desorb H2S, CO2, etc., thereby producing lean methanol and H2S-rich acid gas.
Thorough thermal regeneration of methanol is carried out to completely desorb H2S as well as CO2, thereby obtaining methanol-depleted gas and H2S-enriched acid gas
Thorough thermal regeneration of methanol is carried out to completely desorb H2S, CO2, etc., thereby producing lean methanol and H2S-rich acid gas.
On the left, it goes directly to the methanol tank. On the right side, heat exchange takes place with a reboiler; methanol and water have different boiling points, so methanol vapor rises, creating a density difference. The left side is still connected to the right side, which drives the flow of methanol. As a result, the water content on the right side is higher, and this water is pumped to the water separation tower
