Dresser-Rand Co, USA This system is designed to be an efficient, compact and cost-effective way and method of supplying clean, dry gas to gas seal buffer supply lines and does not require regular maintenance. The system uses a rotary separator, magnetically coupled to a source of rotational power, along with a gas stream cooling unit configured to condense liquids out of a wet gas stream before the wet gas stream is supplied to the rotating separator. The system may further include a gas stream pressure booster; a heating unit to heat a dry gas stream, generated by the rotary separator; and a controlled recirculation loop, configured to continually recirculate the wet gas through the driven rotary separator until the desired amount of condensates are removed from the wet gas stream.
