How to increase the inlet temperature of the synthesis tower while keeping the temperature constant?
There is no way to change it, unless there is valve control to increase the area of the gas-to-gas heat exchanger.
The inlet temperature of the synthesis tower is exchanged by the gas-to-gas heat exchanger. If the gas-to-gas heat exchanger has a secondary line, it should be turned down to increase the heat exchange volume. There is generally no cooler at the outlet of the compressor. It is estimated that the greater the compression ratio, the higher the outlet gas temperature will be, but this cannot be a means of adjusting the gas temperature.
1. Adjust the amount of cold air entering the lower part of the synthesis tower, so that the amount of cold air entering the gas-to-gas heat exchanger is reduced, while the hot air entering the gas-to-gas heat exchanger remains unchanged, causing the inlet temperature of the synthesis tower to increase. 2. To increase the outlet temperature of the compressor or cycler, you can use the method of increasing the compression ratio.
If the equipment is finalized, if the outlet temperature is not adjusted, the inlet temperature cannot be adjusted. It can be seen from the heat transfer equation Q=K·A·Δt that K and A are basically fixed. When the inlet temperature is increased, Q will increase and Δt will decrease, which is not feasible. We can only think of ways to improve the heat transfer coefficient K, such as increasing the heat transfer coefficient K, inserting twist iron into the tube, reducing the baffle spacing, using corrugated tubes, finned tubes, and dense heat exchange tubes. The heat exchange area can also be increased and a heat exchanger added.
