An oil mist eliminator, also known as a mist eliminator or demister, is a device that is used to remove droplets of liquid from a gas stream in oil and gas processing. It is an important component in the process of separating oil and gas, as well as in the transportation and storage of these fluids.
Oil mist eliminators typically consist of a wire mesh or coalescing filters that are designed to capture droplets of liquid as they pass through the device. The droplets are then collected and returned to the process stream, while the purified gas is allowed to pass through.
