I urgently need an expert to help me calculate the air cooler.
Thread Content
Dear experts, if I encounter a problem below and I am not very familiar with the calculation of air cooling, please feel free to give me some advice. Thank you! ! The installation location is Harbin. There are 8 wet vertical tube bundles on the top of the propylene tower for air cooling, model SL9. * 3-6-221-25S-17.4/RL-Iia can no longer meet the cooling load requirements and requires additional air cooling. 1) Calculation data of air cooling at the top of propylene tower. Propylene tower top composition: FLUID MOLAR PERCENTS 1 C2 0.01 2 C3 0.63 3 PRLN 99.36 Current outlet temperature : The gas phase temperature is 45.7 degrees (pressure 1.9MPa), and the liquid phase is required to reach 40 degrees ； flow: 5039 KG-MOL/HR (total) ； It is best to upload the calculation file to facilitate learning * .
Is the total flow mass flow or molar flow? Is the working pressure gauge pressure? What is the design air temperature? What is the specific location, altitude and local atmospheric pressure? My mailbox wangqg3000@126.com
