Where does methanol loss mainly occur? 1. System gas phase carryout ； 2. Methanol carried over in naphtha products ； 3.T04171 Transfer of wastewater from the bottom ； 4. Leaks in the system.
1. Carry out various gases from the system； 2. Methanol carried over in naphtha products ； 3. Carry out the wastewater at the bottom of the methanol water tower ； 4. Leaks in the system.
Leaked with wastewater, through leaks and drips, carried away in the gas phase, present in naphtha products
1. Gases carried out of the system; 2. Methanol carried out in the naphtha product; 3. Wastewater from the bottom of the methanol water tower; 4. Leaks and drips in the system.

1. Gases exiting the system; 2. Wastewater from the bottom of the methanol water tower; 3. Methanol present in the naphtha product; 4. Leaks and drips within the system.
The main aspects include the amount of gas removed for purification, the amount of H2S-containing gas removed, the amount of carbon dioxide gas removed, the amount of exhaust gas removed, the amount of wastewater removed, sampling points, as well as leaks and spills.
1. Carry out various gases from the system； 2. Methanol carried over in naphtha products ； 3. Carry out the wastewater at the bottom of the methanol water tower ； 4. Leaks in the system.
What causes methanol loss in various processes? There are mainly a few reasons: 1. Entrapment during the material distillation process, 2. Residues in the bottom of the tower during methanol purification, 3. Recovery of methanol during the production process
