What is the effect of the methanol overflow at the top of the low-temperature methanol washing recovery tower? What should its liquid level be at normal times?
CO2 separation tower? desulfurized,
In the Luchi process, the level of the liquid is not the key factor; what’s important is to ensure an adequate reflux rate. The purpose of this reflux is to remove H2S from the gas coming from the lower section, thereby ensuring a low total sulfur content in the exhaust gases； In the design, it’s better to install the overflow pipeline at a lower position; after all, there is also the factor of liquid level to consider. Moreover, depending on the pressure difference, the higher the liquid level, the greater the overflow volume ； It has relatively high operational flexibility.
