Storage tank circulation rate and heat exchange

What is stored in the tank? What is the storage period? To what temperature needs it to be heated? Wait, the information needs to be more extensive and comprehensive. If you ask like this, all I can tell you is that the larger the pump you choose, the greater the flow rate will be.

There is too much to calculate: the heat dissipation of the storage tank, the mixing of materials inside the tank, heat exchange calculations for the heat exchangers, and so on

The storage tank has a capacity of 60 cubic meters and is used to store methacrylic acid; the temperature is required to be maintained between 28 and 31 degrees. In my opinion, it is necessary to take into account the heat dissipation from the tank, ensuring that circulation occurs and heat is supplied within the allowed temperature range. I’m not sure how this is taken into consideration, so I would appreciate any guidance from everyone.

I really want to know how to calculate this as well; are there any empirical values that can be used as a reference? If anyone knows, please let me know. Thanks!

1. Understand the amount stored inside the tank and its physical properties (such as specific heat). 2. The flow rate that the pump can deliver (Q). 3. The initial temperature of the tank and the desired temperature to be reached (temperature difference). ↑ With these values, it’s possible to calculate the amount of heat required. --------------------------------------------------------------- 4. The expected temperature difference and specific heat. ↑ Using these values, an approximate flow rate can be determined. -------------------------------------------------------------- By using these two factors, it’s possible to determine the size of the inlet and outlet pipes for the heat exchanger. --------------------------------------------------------------- Basically, this heat exchanger should be a shell-and-tube type; its U-value can be estimated. After calculating the LMTD, the desired area of the heat exchanger can be determined. From there, decisions can be made regarding the size and length of the tube bundles, etc. In this way, the heat exchanger can be designed. (It’s best to include a margin of safety to allow for flexibility in future operations.) ------------------------------------------------------------------- One recommendation is to use temperature sensors and thermometers so that temperature can be monitored in real time once the material is heated. Additionally, using sequential control for hot water management helps to maintain the temperature in the tank at the desired level. -------------------------------------------------------------------- These are my personal experiences, provided for reference only

It’s very simple: first, calculate the heat loss of the storage tank, using the average highest temperature during the hottest month of summer as a reference. For the process fluid side of the heat exchanger, the inlet temperature is set at 31°C and the outlet temperature at 27°C. The heat load of the heat exchanger is taken as 1.5 times the cooling loss of the storage tank as a safety margin; low-temperature water at 7°C is used on the cold side with an outlet temperature of 12°C. When calculating the area of the heat exchanger using EDR, no additional margin is considered, and thus the heat exchanger can be simulated and calculated accordingly.

I am also designing a MAA storage tank with a capacity of 3,000 liters. I’m not sure whether this type of medium needs to be heated or cooled using a heat exchanger It solidifies when the temperature is below 15 degrees and decomposes at around 40 degrees. I haven’t designed this system before, so I would appreciate some guidance from those who are more experienced. You use hot water for heating, while I use cooling water for cooling; the normal temperature of the material in my system is 20 degrees
