Faq of Value of air separation unit
The purified air enters the fractionator and exchanges heat with the returned polluted nitrogen, oxygen and nitrogen through the main heat exchanger. After cooling, a small part of it is liquefied, and the gas-liquid mixed air is throttled to the pressure of 0.55 MPa. After distillation, 99.999% pure nitrogen is obtained at the top of the lower column, and then it enters the main cooling column, and is condensed into liquid nitrogen by evaporation of liquid oxygen in the upper column. A part of liquid nitrogen is returned to the lower column as reflux liquid, and the remaining liquid nitrogen is throttled after cooling. Enter the sprayer at the top of the upper column. The bottom residue is liquid air containing 38% oxygen. After passing through the liquid air subcooler, it enters the middle of the upper column to participate in distillation. At the same time, the polluted liquid nitrogen flow is drawn out from the middle of the lower column and then enters the upper column as reflux l

The water supply source of air cooling column in precooling system equipment is cooling water pump, and water cooling column is supplied by chilled water pump. Their structures and principles are described as follows: 1. Design structure: the most basic components inside the centrifugal pump are high speed impeller and fixed volute pump case. Generally, the impeller with several (4 ~ 12) backward curved blades is fixed on the pump shaft and driven by the motor to rotate with the pump shaft at high speed. The work done by these impellers will directly act on the liquid in the pump body, which is the energy supply source device of centrifugal pump. 2. Principle: after the centrifugal pump is started, the pump shaft directly drives the reverse curved impeller to move at high speed, squeezing the pre filled liquid between the reverse curved spaces of the blade to rotate. Under the high-speed centrifugal force formed by the movement of the pump shaft, the liquid moves radially from th
