Why is this heat exchanger so strange?
Thread Content
The oil and gas from the top of the catalytic fractionation tower, after being air-cooled, enters the circulating water-cooled heat exchanger. Today, I measured the temperature difference between the upper and lower parts of this heat exchanger (model: RCBOS1100, counterflow rod-type condenser); the temperature in the upper part was around 60 degrees, while it was around 40 degrees in the lower part. What’s causing this? Why is there a difference in temperature between the upper and lower parts of the heat exchanger?
Is there too much dirt in the upper part, which is affecting the heat exchange efficiency?
Is it because the upper part is the heat source inlet? ?
Although the upper part is the heat source, thanks to the baffle plates, the oil and gas move back and forth up and down within the heat exchanger; so why is the temperature higher in the upper part?
The possibility isn’t very high, as all these heat exchangers on the oil and gas pipeline branches are in the same condition.
It’s possible, but there is no other way yet to determine whether it is indeed the cause of scaling
The key is whether the heat exchanger meets the design requirements and can satisfy the process needs
Personally, I wonder if there’s too much dirt accumulated at the bottom
Temperature difference between the inlet and outlet of the heat exchanger. The greater the material flow rate, the larger the temperature difference.
