Methanol section: One question per day. How is the inlet temperature of the synthesis tower determined? 2016.04.17 How is the inlet temperature of the synthesis tower determined? Answer: The inlet temperature of the synthesis tower is a very important operational parameter. It is determined based on factors such as the catalyst’s active temperature and heat resistance, as well as the characteristics of the methanol synthesis reaction and the chemical reactions involved. As a general rule, the inlet temperature should be high enough to maintain the catalyst’s activity and enable the gases to react; at the same time, it should not exceed the catalyst’s maximum tolerable temperature. To ensure efficient reactions, the inlet temperature should be kept as low as possible, which helps to extend the catalyst’s service life.
How is the inlet temperature of the synthesis tower determined? Answer: The inlet temperature of the synthesis tower is a very important operational parameter, which is determined based on factors such as the catalyst’s active temperature and heat resistance, as well as the characteristics of the methanol synthesis reaction and the chemical reactions involved.
1. Adjusting the circulation volume. 2. Controlling the hot and cold bypass lines. 3. Control of methane in the system. 4. Control of ammonia content at the inlet of the synthesis tower. 5. Control of the outlet temperature of the waste heat boiler

The inlet temperature of the synthesis tower is a very important operational parameter, which is determined by taking into account factors such as the catalyst’s active temperature and heat resistance, as well as the characteristics of the methanol synthesis reaction and the chemical reactions involved
The inlet temperature should be determined by the technology provider at the design stage, based on the properties of the catalyst selected
It is determined comprehensively based on the catalyst’s active temperature and heat resistance temperature, taking into account the characteristics of the ++ methanol synthesis reaction as well as chemical reactions and other factors.
If both the inlet and outlet temperatures are low, the pressure in the synthesis drum should be increased； If the outlet temperature is high and the inlet temperature is low, it may be due to poor heat exchange efficiency in the preheater before the tower; the heat exchanger should be cleaned ； If self-heating is not possible for some reason, the flow injector can be activated (as a temporary emergency solution) ； If it is caused by too low a load, increase the load ；
It is determined comprehensively based on the catalyst’s active temperature and heat resistance temperature, taking into account the characteristics of the ++ methanol synthesis reaction as well as chemical reactions and other factors.
The inlet temperature of the synthesis tower must be above the minimum activity temperature of the catalyst to ensure that the gases can react.
The inlet temperature is controlled based on the performance requirements of the catalyst, and ultimately the outlet temperature of the synthesis tower is regulated by adjusting the drum pressure; once the outlet temperature is well controlled, the inlet temperature can also be maintained at the specified level.
