Do people often encounter such situations, where fluctuations in the operating conditions of low-temperature methanol washing in coal chemical plants result in methanol being present in the acidic gases used for sulfur recovery? Which components in those acidic gases ignite and burn first once they enter the sulfur production furnace? Why?
Should the acid gas (shunt) in the middle of the sulfur production combustion furnace be stopped in this situation? In any case, methanol won’t burn completely, right?
Methanol enters the combustion furnace, where the existing air supply is severely insufficient, resulting in incomplete combustion and the formation of carbon black.
Regarding the sequence in which various substances react inside the reactor, I recommend that you read the book \"Kraus Sulfur Recovery\"; it has been shared by someone on the forum, so you can search for it!
Following this question, what is the impact of a small amount of ammonia (0.2% v) present in acidic gases on sulfur recovery?
Acidic gas contains ammonia; regardless of the amount present, if the temperature in the sulfur production furnace is not high enough to burn the ammonia, ammonium salts will be formed, which affects the operation of the sulfur recovery unit. In cases where the ammonia concentration in the acidic gas is high, ammonium salts are formed more quickly, while when the ammonia concentration is low, it takes longer for ammonium salts to form.
