Methanol Purification Version – Daily Question 20200601

Thread Content

How is inert gas controlled in the methanol synthesis process? Answer: The synthesis system uses a small amount of gas behind the emission separator to control the accumulation of inert gas within the synthesis system. General control principles: Different process designs have varying requirements. Usually, at the beginning of catalyst use, when its activity is high and the load on the synthesis tower is low, the inert gas content in the circulating gas can be kept at around 20-25%; later on, it should be maintained at around 15-20%.

Keep it at 20---25% in the initial stage, and at 15---20% in the later stage.

After the crude alcohol separator lies the area with the highest concentration of inert gases, from which they are removed. A hydrogen recovery system is installed to recover hydrogen, while the exhaust gas is used as fuel and supplied to other units. An excess of inert gas increases power consumption, which is not conducive to energy conservation and emission reduction; however, an appropriate amount of inert gas does have some benefits, as it reduces the partial pressure of the active components, thereby preventing the reactions in the synthesis tower from becoming too intense.
