Seek a sealed VOC recovery solution for oil separators
Thread Content
I need a detailed plan for the sealed recovery of VOCs from an oil separator tank. Thank you. Ten years ago, the oil separation tanks were open; now they need to be made airtight for recycling, and it seems a bit difficult – what additional equipment is required?
Add a fan, an activated carbon adsorber, and an exhaust stack
We are facing the same issue and are working on fixing it.
What oil is in between? How much is the emission? What happens to it after it’s recycled? A plan can only be determined after it is clarified. Sealing can involve using a lid, and recycling can involve adsorption, but these are not the ultimate solutions, as new pollutants—hazardous waste—may be generated.
I came up with a basic idea: add an openable cover to the top of the oil separator tank, as it is necessary to periodically remove the oily substances that float on the surface. The pipes for collecting oil vapor from this cover are connected to the inlet of a water ring vacuum pump or fan; these pumps or fans are used to cool the oil vapor to 5–10°C using an acrylic cooler, after which it is sent to a container. Dehydration takes place at the bottom of this container. An additional small pump is installed to periodically transfer the collected oily substances back to the tank containing lighter oils within the system, where those lighter oils can be sent to previous units for reprocessing. I wonder if it’s possible?
