  1. The cold box foundation is composed of foundation body, water baffle, cold insulation layer and surface layer.

 

  1. The surface of fractionator foundation after completion shall meet the following requirements:
  2. a) There should be no cracks and other defects on the surface;
  3. b) The surface should be clean,and no inflammable materials such as wood board and linoleum are allowed to be carried;
  4. c) Surface flatness < 5 / 1000;
  5. d) The surface levelness is less than 5 / 1000, and the total length shouldnot be more than 15mm.

 

  1. After the foundation is qualified, mark the installation center line of the container according to the installation position of the vessel, and mark the direction and position of the pipe orifice.

Generally, the actual cooling capacity of expander is always less than the theoretical cooling capacity. Under the same inlet and outlet pressure and inlet gas temperature, the lower the efficiency of expander, the smaller the unit refrigerant cooling capacity and the smaller the temperature drop efficiency of expander. The efficiency of expander depends on the size of various losses inside the expander. Due to the existence of various losses, the ability of gas to do external work is reduced in varying degrees. To sum up, the losses mainly include the following aspects: 1. When the air flow passes through the work wheel and the deflector, the loss caused by friction and air flow impact on the runner surface is called flow loss. 2. When the impeller is rotating, the friction heat generated by the gas around the wheel disc will increase the temperature of the gas, which is called friction blast loss. 3. When the gas passes through the deflector, the leakage from the gap bet
