How to control the temperature of the synthesis tower? The temperature of the synthesis tower is primarily controlled by adjusting the steam pressure in the steam drum. At around 4.0 Mpa, a change of 0.1 Mpa in steam pressure results in a temperature change of approximately 1.35°C. Using the steam pressure from the synthesis steam drum to control the tower temperature is both simple and reliable. The temperature of the synthesis tower is generally adjusted appropriately depending on the usage time of the catalyst. When the methanol production or the pressure difference in the synthesis tower cannot be maintained above the specified values even by adjusting temperature, pressure, and space velocity, it is necessary to shut down the plant to replace the catalyst.
The inlet temperature is determined by the heat exchange between the mixture gas and the gas exiting the synthesis tower. Since the temperature of the recycle gas remains relatively stable, the temperature of the gas exiting the synthesis tower and the space velocity are the main factors affecting the inlet temperature.
