CO2 compressor four-stage outlet temperature
Thread Content
What is an appropriate temperature to control for the four-stage outlet temperature of the CO2 compressor (the temperature entering the stripping tower)? What is the specific impact of this temperature level on the thermal equilibrium of the high-pressure ring?~
It should be around 120°C; higher temperatures can cause fluctuations in the temperature of the liquid exiting the stripping tower. Based on our observations, this temperature does not have a significant impact on the thermal balance of the high-pressure system. The gas used for stripping rises upward within the tubes of the stripping tower, while the shell side is heated by saturated steam at 218°C, so this also has little overall impact. Additionally, if abnormal operating conditions occur, such as poor control of the temperatures in the three stages or equipment failures, which lead to changes in flow rates, then there is still some impact. Furthermore, the production parameters are in one-to-one correspondence; a certain load corresponds to a certain saturated steam pressure measured for the E201 shell.
Reply to 2# bingxuelian421: Ignoring everything else, what is the difference between controlling the temperature of this CO2 stream entering the stripping tower at 110°C and 120°C?
1. Temperature changes affect the measurements taken by flow meters; the greater the temperature deviation, the greater the deviation of the flow rate from its true value. 2. If the temperature is too low, less heat enters the stripping tower, which affects its stripping efficiency. 3. If the temperature is too high, it can cause corrosion of the tubes in the stripping tower and an increase in side reactions
