Abstract: A system and method for supplying clean dry gas to gas seals of a compressor. The system uses a rotary separator magnetically coupled to a source of rotational power, along with a gas stream cooling unit configured to condensate 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 a desired amount of condensates are removed from the wet gas stream.

Abstract: A shaftless compressor module (10) has a module casing (11) containing an axial chamber (14) and an annular chamber (15) coaxially with the longitudinal axis (16) of the axial chamber. An annular motor stator (33) can be fixedly positioned in the annular chamber coaxially with the longitudinal axis of the axial chamber. An annular motor rotor (31) can be positioned in the annular chamber coaxially with the annular motor stator. A shaftless impeller (22) is rotatably mounted within the axial chamber. The impeller has a plurality of impeller passageways (27), with one end of each passageway being open to the inlet of the module casing and the other end of each passageway being located in a radially outer periphery of the impeller. Magnetic bearings (51, 52, 54, 55) can counter axial and radial thrust. Annular gas seals (62) can prevent gas flow through the annular chamber. A plurality of these modules (10) can be connected together to form a multiple stage shaftless compressor wherein each impeller can be driven at a different speed.

Abstract translation: 无轴压缩机模块（10）具有包含轴向室（14）的模块壳体（11）和与轴向室的纵向轴线（16）同轴的环形室（15）。 环形电动机定子（33）可以与轴向室的纵向轴线同轴地固定地定位在环形室中。 环形电动机转子（31）可以与环形电动机定子同轴地定位在环形室中。 无轴式叶轮（22）可旋转地安装在轴向室内。 叶轮具有多个叶轮通道（27），每个通道的一端对模块壳体的入口开放，每个通道的另一端位于叶轮的径向外周边。 磁力轴承（51,52,54,55）可以抵抗轴向和径向的推力。 环形气体密封件（62）可以防止气体流过环形室。 多个这些模块（10）可以连接在一起以形成多级无轴压缩机，其中每个叶轮可以以不同的速度驱动。
