Air separation unit safety

Air separation unit safety
The safety of air separation unit is very important in the production process. Therefore, the design and installation of oxygen, nitrogen and argon pipelines should be reasonable and compliant to avoid defects, resulting in leakage or explosion. In addition, attention should be paid to valve selection, material selection and installation of air separation unit to avoid leakage caused by loose sealing surface.

Almost all motors commonly used in the air separation plant are three-phase AC motors. Three-phase AC motor can be divided into asynchronous motor and synchronous motor. The rotating speed of the synchronous motor and the frequency of the power grid keep a strict relationship, namely: N = 60f/P in the formula P -- magnetic pole logarithm; f -- grid frequency, the normal situation is 50Hz; n -- motor speed, r/min. For example, for two-pole (P = 1) synchronous motor, the synchronous speed is 3000r/min; for four-pole motor, P = 2, n = 1500r/min. While the rotating speed of asynchronous motor is always less than that of synchronous motor, and it generates rotating torque by its phase difference. Asynchronous motor is most widely used. It consists of a stator and a rotor, and has a stator and a rotor winding respectively. The stator winding is made of copper (aluminum) wire with outsourcing insulation. With the difference of rotor winding, asynchronous motor can be divided into squirrel ...

In order to check the installation quality, deformation under low temperature and smooth condition of pipelines, valves and field installed air separation plant in air separation column, needs to be further tighten the flange bolts at low temperature. It is necessary to start freezing before filling the cold insulation box with cold insulation material, which is called naked cooling. During naked cooling, the rectification column, main condensing evaporator and other main equipment shall be cooled to the minimum temperature for 2 hours respectively, and then the whole air separation unit shall be cooled for 3 to 4 hours. The deformation and leakage of each part shall be checked in detail, and the flange bolts shall be tightened again. After defrosting, the flange shall be heated to normal temperature before gas seal test can be conducted.
