What are the effects of air velocity on methanol synthesis? Answer: The air velocity is usually determined by factors such as the power of the circulator and compressor, as well as the resistance in the synthesis system. When the space velocity is too low, the composition of the reaction gas mixture is closer to the equilibrium composition; thus, less power is required, the area of the heat exchanger needed is smaller, the temperature of the gas exiting the reactor is higher, allowing for better utilization of thermal energy. However, the production rate of the catalyst is low. The air velocity is too high, resulting in a lower methanol content in the gas mixture involved in the reaction process; this leads to higher energy consumption, an increased requirement for the area of the heat exchanger. The temperature of the gas exiting the reactor is low, which reduces the value of heat energy that can be utilized, although the production rate of the catalyst is high. In the methanol production process, the space velocity is generally controlled between 10,000 and 30,000 h-1.

Increasing the space velocity reduces the one-way conversion rate, slowing down the catalytic reaction, which helps to protect the catalyst and increase yield. However, increasing the space velocity raises the energy consumption during the circulation phase; if the space velocity is too high, the reaction temperature drops significantly, and sometimes it becomes difficult to maintain this temperature, resulting in a decrease in yield.

The space velocity of the synthesis tower is often determined by factors such as the power of the circulator and the resistance in the synthesis system. If a lower space velocity is used, the composition of the gas mixture during the reaction is closer to the equilibrium composition; the catalyst production rate is lower. However, less gas volume is required for each unit of methanol produced, resulting in reduced energy consumption for gas circulation. The heat exchange area needed to preheat the unreacted gas to the catalyst inlet temperature is also smaller, and the temperature of the gas leaving the reactor is higher, giving it greater value in terms of thermal energy utilization. If a higher space velocity is used, the catalyst production rate can be increased, but it increases the heat transfer area required for preheating.
