Regarding water cooling of coker liquefied gas
Thread Content
There are four sets in total, two for liquefied gas cooling. At first, all of them were in use; later, to reduce consumption, one set was taken out of service. Now it’s necessary to put everything into use, but when that is done, it turns out that the group that was removed earlier seems to not be functioning properly; the wall temperature of that group is much lower compared to that of the group that has been in use throughout. How can this problem be solved?
LPG has a high sulfur content, so the filter should be backwashed regularly
It’s possible to make the good group operate at a lower level so that the poor group can move more, as the obstruction caused by the inactive group shouldn’t be too severe
Due to the low liquid flow rate and slow velocity of the liquid, insufficient driving force is available when the cooler is switched back on, resulting in an inability to raise the temperature; in such cases, reducing the valve opening of the operating cooler will suffice.
Is that group clogged due to water accumulation?
