Why is the temperature of the gas exiting the synthesis tower raised to 210°C? In the case of long-term or temporary parking, the temperature of the methanol synthesis tower is low; it is necessary to raise the temperature of the gas exiting the synthesis tower to 210°C before allowing gas to flow in. Why is this?
It mainly controls the occurrence of side reactions and the formation of higher alcohols, while also reducing the load on distillation and improving the quality of the product
Our operating procedures require this; conducting a thorough analysis of the reasons is aimed at enabling better operations. 1. Avoid the formation of paraffin and fusel oils. 2. Maintain the thermal balance of the synthesis tower. 3. The temperature rises to 210°C, and the temperature and pressure in the drum also reach equilibrium. Avoid too rapid temperature rise after catalyst and drum venting.
