Leak in the distillation cooler
Thread Content
Let’s discuss the impacts of leaks in the distillation cycle water coolers, especially what should be paid attention to when circulating water leaks into the system
We are currently experiencing leaks in the atmospheric tower cooler; the leaks occur almost once a month, causing serious disruptions to production. Now the load can’t even be increased very much
Reply 1# YKQB: The cooling water from the distillation cooler enters the distillation tower, causing a drop in temperature at the bottom of the tower, which leads to losses of steam or heating medium； At the same time, it pollutes the distillation medium, thereby having a significant impact on the quality of the product. Upon detecting this situation, stop the machine immediately, conduct leak checks, and carry out repairs without delay.
What was said upstairs is correct. For example, if there is a leak in the cooler at the top of the tower, the product is definitely unqualified, without any room for discussion. In the case of methanol distillation, the water content in the methanol product is measured in ppm levels; once a leak occurs, the entire batch of product becomes unqualified. If operations are not stopped, the product has to be returned to the crude methanol tank, and soon the tank will be full, forcing a stoppage of operations. Moreover, the earlier the leak is detected, the sooner operations can be stopped, resulting in less damage.
Reply to 2# YKQB: It is advisable to consider having a backup cooler, with one in use and one as a backup, allowing for online switching to ensure continuous production!
It depends on the moisture requirements of your system; if the material is sensitive to water, that will be a problem； If water is not a concern, it may lead to product department compliance and operational stability. At this point, decide whether to perform a planned stop or an emergency stop based on the actual situation!
The condenser is a problem; we often encounter this issue here, which adds a lot of extra work. The main issue lies in equipment procurement; inferior products are purchased at the same price
This is likely a problem with the quality of the equipment. I agree with the view expressed on floor 5: installing two sets of condensers, one as a backup, would be a good solution. As the original poster mentioned, internal leaks can lead to blockages, which indicates that the material is sensitive to water. Therefore, it’s important for operators to detect problems as soon as possible, and to shut off the water supply promptly when issues arise, in order to prevent the situation from worsening
By \"plugging the leak,\" I mean using the parking opportunity to seal the leaking pipe bundle.
