Abstract
A dry-running gas seal includes a stationery seal ring carrier holding a stationary seal ring, a rotary seal ring carrier holding a rotary seal ring facing the stationary seal ring, scoops radially outside and extending toward the rotary seal ring carrier, and a heat exchanger in fluid communication with the scoops, whereby the portion of the gas is trapped by the scoops and transferred to and cooled by the heat exchanger and returned to and the high pressure area adjacent to the seal.
