I would like to ask about the setting of the sewage discharge process for the separator

There is a foreign project involving the sewage treatment system for the inlet separator at the gas transmission station; this system is equipped with measuring devices as well as cyclone separators. The gas separated out is vented on-site, while the liquid goes into a sewage tank. I would like to ask the experts: what is the purpose of using cyclone separators in this sewage tank system? The medium is the conventional dry gas processed by the natural gas processing plant; the operating temperature in this facility is relatively low, as it is located near the Arctic
What is this medium of yours? What components are included. Is it convenient to talk about it?
Judging from the process, it seems that the intention is to recover some more light components.
The cyclone separator can be placed inside the tank, combined with the subsequent tank to separate the flash vapor, thereby simplifying the process.
It depends on what media are available; it should be gas-liquid separation
My understanding is: 1. Your separator should be operated under pressure. 2. Is it gas-liquid separation? 3. Due to the pressure present, a cyclone separator is added at the end to allow the gas to be discharged. Transfer the heavy-phase oil contamination to the storage tank. I’m not sure if it’s correct?

Since natural gas passes through the bedroom separator, a small amount of it ends up in the sewage pipeline system along with oily wastewater, eventually reaching the buried sewage tank. From there, it escapes gradually through the vent valves, which constitutes a waste of resources and also creates a risk of explosion at the site. As shown in the figure, with the aim of saving energy and reducing consumption, a cyclone separator has been added to the process between the sewage pipeline and the buried tank to separately separate oil, gas, and water from the sewage once again. The separated natural gas returns to the gas pipeline for circulation through the upper part, while the liquid flows into the buried tank via the sewage pipeline. In fact, adding a cyclone separator is highly beneficial for improving the overall safety, environmental protection, and energy efficiency of station operations. I really hadn’t thought about this before; not many stations in domestic gas fields have adopted such a solution – it’s a useful perspective to consider
Personally, I think it is also aimed at achieving separation of the components within the system; by utilizing centrifugal force and sedimentation, the gas is expelled so that the liquid can be collected
If it is natural gas from a wastewater treatment system, then the volume of this cyclone separator should not be large, as after all, the gas coming out of the filtration and separation unit in the wastewater system is minimal; most of it is liquid, along with sludge. It would be best if the poster could attach a complete process flow diagram, for example, where does the light phase flowing out of the cyclone separator go? It’s also for us to learn from*.
