Temperature control issue in the droplet addition pipeline
Thread Content
Guys, during the slow addition process in chemical process reactions, is it better to control the reaction temperature by interlocking the control valve on the addition pipeline with the reactor temperature, or by interlocking it with the liquid level in the addition tank? I hope netizens can provide their opinions; thank you!
The temperature lags too much; if a large amount is added in a short period of time, the risk is high. We are linked to the weighing of the dropper tank above.
Thank you very much. Yes, the lag in the temperature interlock with the control valve is too severe.
Bro, there’s another question: for adjusting the flow rate of the hot and cold media in the jacket, what method do you use to do that? Is it an interlock between the control valve and the flow meter? If there are also latency issues with the control valve and temperature interlock?
Dude, where are you guys from regarding weighing instruments?
We work with temperature in relation to the refrigerant; at first, we adjust the temperature setting while proceeding with the process, trying several times to determine what temperature is appropriate. The temperature will rise initially, and we check how much more it can go up. After closing the valve, we see how much the temperature can drop. We then keep the upper and lower limits within acceptable ranges, and finally set the appropriate temperature value. Heat transfer steam is linked to pressure, and most of the others are linked to temperature as well. And for flow regulation, controlling the flow is also no problem.
Mettler Toledo is used quite often
Thanks, bro, really appreciate it!
