Full liquid air separation plant

Full liquid air separation plant
The total liquid air separation unit can be divided into low circulation and medium pressure circulation according to different working pressure levels. When the liquid product is more than 2000-3000m3 / h, it will be a large and medium-sized liquid air separation plant, which needs more cooling capacity. Therefore, the process flow must be changed from low-pressure circulation to medium pressure cooling cycle.

There must be enough smooth straight pipe sections before and after the flow orifice plate. The distance is 10 times of pipe diameter in front of the orifice plate and 5 times of the pipe diameter behind the orifice plate, and no factors affecting the measurement accuracy (such as pipe joint, etc.) are allowed. The inner surface of the pipe weld should also be ground smooth, and the gasket should not extend into the inner diameter of the pipe. And carefully check the installation direction of the orifice plate, do not install it in reverse. (judgment method: the small exit is the entrance, and the large exit is the outlet)
