What is the waste heat of a general chemical plant?
Thread Content
Let's discuss it. After the heat source in a chemical plant is heated, at what temperature is it generally considered unusable?
Compared with the absorption central air-conditioning industry, it generally cannot be used below 80 degrees! Of course, there are also cases where 60 or 79 degrees can be used!
What about general heat exchangers? We know that heat exchangers in chemical plants account for a large proportion in chemical plants.
I went to the steelmaking plant to do research. The outlet temperature of their slag washing water is 60~80°C, which is already a low-temperature heat source, but it can be used for lithium bromide refrigeration. This post was last edited by jy03018705 on 2009-3-11 16:44 ]
Full and reasonable utilization of low-temperature heat sources is a trend in chemical industry
Now it is basically controlled below 150℃
