An industrial oil degassing system and method to remove gas from an industrial machine oil. Described is an industrial oil degassing system, including a pressure tank under pressure to receive oil charged with gas, a separation tank with an atmospheric pressure to separate gas from the oil, and a seal oil tank with an atmospheric pressure to receive the degassed oil from the separation tank. Further described is a method for industrial degassing of oil with the steps of exerting a pressure to a pressure tank, supplying the oil to the pressure tank, supplying the oil from the pressure tank to a separation tank with atmospheric pressure, separating gas from the oil in the separation tank, and supplying the degassed oil to a seal oil tank with atmospheric pressure.
