Can a horizontal air-cooled or air-cooled unit be modified to a wet-type version?
Thread Content
Currently, the initial overhead cooling in atmospheric and vacuum distillation units is of the horizontal air-cooling type. Due to changes in the oils being processed, the temperature after cooling remains high. Is it possible to modify this system to use wet air cooling? Will such a modification affect the safety of equipment operation?
Try adding a ring of misting nozzles at the air inlet.
I’m not sure how other companies handle wet air cooling, but ever since we started using it, we haven’t used it again. First of all, demineralized water is required; otherwise, scaling occurs after just a few days of use. All the dust inhaled the second time will be washed away by water ； The air-cooled bearing after the third spray is a test
Wet air cooling requires demineralized water; otherwise, scaling is likely to occur
The temperature after air cooling is high. 1. It is recommended that you check the fins to see if there is any lint blocking them, which can be cleaned. 2. Adjust the process flow; I’m not sure how many tube passes your air cooler has, but you can slightly reduce the outlet valve opening to increase the residence time of the oil and gas mixture in the air cooler. It is recommended that you adjust this setting yourself. 3. For wet air cooling, water quality must be taken into account to prevent scaling; the misting method also needs to be considered, as fan bearings and motor bearings are prone to damage. Consider the environmental impact: whether the sprayed water is recycled or discharged directly. During the summer, I encountered situations where the air-cooling temperature was high; the first two methods solved that problem. You can give it a try and discuss it together.
