If the propylene separated by the gas separation unit is not dried, can its water content be kept below 10PPM?

In the Shandong region, if the propylene separated by the vapor separation unit is not dried, can its water content remain below 10PPM?
That’s impossible; it’s dry here, and the solid alkali in both towers dissolved away in less than a year……
Sure, just strengthen the reflux tank at the top of the propylene column and add water
In the southern regions, there is no need for drying at all; it is sufficient to strengthen the dehydration process in the propane removal tower and the ethane removal tower
The water content in our propylene is generally between 7-13 ppm. Could the water content in propylene be related to the regional climate?
Control should be exercised from the raw materials, and then water separation should be enhanced in the top reflux tank. The dryness the OP is talking about? ? I don’t understand
Control should be exercised from the raw materials stage
