    摘要: Sulfonation of a sulfonatable organic compound is effected by means of a two-stage reaction with an SO.sub.3 -containing gas, in which the first-stage reaction is carried out by flowing, in parallel flow relation, said organic compound and said SO.sub.3 -containing gas upwardly into the lower ends of a plurality of vertically positioned cylinders or double-cylinders, and the second-stage reaction is carried out by the steps of collecting the reaction product of the first-stage reaction, adding fresh SO.sub.3 -containing gas to the reaction product thus collected and flowing in parallel flow arrangement the reaction mixture downwardly into the upper end of a vertically positioned cylinder or double-cylinder.

    摘要: A high speed compressor (10) includes a gear box (11), two compressing units (12, 13) supported on opposite side walls of the gear box (11) and a bull gear (32) rotatably placed in the gear box (11). Each compressing unit includes a scroll (15, 16) and an impeller (18, 19) rotatably housed in the scroll (15, 16). The impellers (18, 19) share an impeller shaft (22) extending into the gear box (11). A pinion gear (23) is mounted on the impeller shaft (22) such that it engages with the bull gear (32). A drive shaft (30) extends from the bull gear (32) out of the gear box (11) along a center axis of the gear box (11). An induction motor (35) is connected with the drive shaft (30) for causing the impellers (18, 19) to rotate by way of the bull gear (32) and the pinion gear (23). An inverter (40) is connected with the induction motor (35) at its one end and with a commercial power source (43) at the other end for converting an A.C. power from the commercial power source (43) into an A.C. power having a desired frequency and feeding it to the induction motor (35) for driving of the induction motor (35).

    摘要: A centrifugal compressor (1) including a single rotating shaft (5), a first (upstream) and second (downstream) impellers (2, 3) mounted on ends of the rotating shaft (5) respectively, and a casing (4) for accommodating these impellers. An air path (35) is provided for introducing an air pressurized by the upstream impeller (2) to the downstream impeller (3). An abradable layer (34) is embedded in the casing inner wall (4) such that it faces and is cut by the second downstream impeller (3). The expensive abradable layer (34) is only provided for the downstream impeller (3) since the effect of the abradable layer (34) is significant when provided for the downstream impeller.
