摘要： PURPOSE:To restrain energy loss and pressure loss, and also to prevent the heat from the outside from being input into a pump body. CONSTITUTION:A canned motor 4 is provided to the upper part of a pump body via a shaft casing 3, and the pump body is driven by the canned motor 4. A radiating plate 6 is fixed to the shaft casing 3 for preventing dew condensed water from intruding into the cold insulator 42 surrounding the pump body, and also for preventing the heat from the canned motor 4 from being input by heat transmission. Further, a heat insulating material 9 is interposed between the pump body and a fitting base seat 8 for preventing heat input. The refrigerant for cooling the motor is, for instance, mixed alcohol or alcohol water, and is circulated and cooled by a heat exchanger 5, and the temperature of the motor-cooling refrigerant is 40 to 50 deg.C and it is a low viscosity liquid, so that friction loss can be reduced, and further since the pump is not constituted so as to return the refrigerant to the suction port of the pump body, pressure loss us reduced, and also energy loss can be reduced.

摘要： PURPOSE:To reduce the range of control of concentrated gas and to rapidly return it to the original concentration by using a gas separation membrane module capable of sufficiently reducing the rate of change in concentration of a specified component in concentrated gas as compared to the rate of change in concentration of the specified component in natural gas. CONSTITUTION:In the treatment for separating a specified component from natural gas at a specified concentration by using a separator, one fan (or compressor) 3 and the other fan (or vacuum pump) 4 are driven to feed the natural gas from a natural gas source 1 to a gas separation membrane module 2. A pressure adjusting valve 6 is adjusted to set differential in pressure across the membrane of the gas separation membrane module 2 to a prescribed value and the natural gas is subjected to separation treatment. In this way, concentrated gas of the specified component is allowed to flow out from an outlet 21 on the impermeable side of the gas separation membrane module 2. The change in concentration of the specified component is detected by a gas concentration detecting element 5 and a flow control valve 7 is operated based on the detected signal, thereby the concentration of the specified component can always be kept constant.
