Regarding whether to install wastewater discharge systems in liquefied hydrocarbon storage areas
Thread Content
Are facilities for discharging production wastewater required in all liquefied hydrocarbon tank farms? For example, ethylene, propane, propylene, C5, etc. Our plant’s tank farms for ethylene, propane, and propylene are not equipped with facilities for discharging production wastewater; they only have facilities for discharging rainwater. In contrast, the C5 tank farm has both facilities for discharging rainwater and those for discharging production wastewater. Pump rooms are available in all of them as well. Could some expert please give an answer? .

There are always sump pits, but the problem is that these sump pits collect rainwater. What if the water is contaminated or there is a leakage of some substances? Isn’t it necessary to have separate collection facilities in such cases? Do ethylene and propane vaporize immediately upon leakage, while C5 exists in liquid form at room temperature and thus needs to be collected?
It is related to the production process; for example, if the products manufactured contain water, then water removal operations and a corresponding wastewater disposal system are required. The wastewater drainage system in the pump area may be related to pipeline disposal requirements.
You’re right; once the light components leak out, they will vaporize instantly. You can notice that in the ball tank area with light components, there are no very high fire dikes; instead, there are only relatively low enclosures, as it is not assumed that the leaked material will remain in liquid form – once it turns into a gas phase, it cannot be collected.

If there is a risk of material leakage, and such materials do not vaporize easily after leaking, then a drainage system is necessary, for substances such as C5 and lubricating oils. Generally, liquid hydrocarbon tank farms do not have a sewage disposal system. The wastewater discharge from the pump room is mainly related to substances such as lubricating oil
