Process flow
（1）The air compression process involves using an air compressor to effectively increase the pressure of the air, bringing it to a range of 0.5-0.7 Mpa.
To ensure efficient operation of the air conditioning system, pre-cooling is required. The air is first pre-cooled to a temperature of 510 in the pre-cooling unit, and the moisture is then separated to improve performance. This process ensures that the air circulated into the system is of the right temperature and has reduced moisture content, which helps in achieving optimum results. Proper pre-cooling of the air conditioning system is essential in ensuring that the temperature regulation is effective and energy is not wasted.
The molecular sieve purifier eliminates any remaining moisture, carbon dioxide and hydrocarbons from the air during the purification process.
During the air expansion process in the expander, the cooling capacity needed by the device is fulfilled as the air expands and subsequently cools.
In the process of heat exchange, the heat exchanger within the fractionation tower facilitates the transfer of heat between the air and the refluxing oxygen, nitrogen, and dirty nitrogen. This exchange results in the air being cooled to its liquefaction temperature. Subsequently, the cooled air is utilized to repeatedly heat the refluxing oxygen, nitrogen, and dirty nitrogen back to the ambient temperature. By efficiently managing the heat transfer, the system ensures that the gases are maintained at appropriate temperatures throughout the process.
Subcooling refers to the process of cooling liquid air and liquid nitrogen prior to supercooling and throttling nitrogen in the subcooler.
In the rectification tower, the air is separated and rectified to obtain ammonia as the final product at the top of the upper tower while oxygen is obtained at the bottom. This process ensures efficient and effective separation of the components in the air.
