DEAR Air Separation's heart and romance

When the precooling system of the cooler breaks down, what influence will it have on the operation of the air separation plant? How should it be operated?

The applicable range of the working temperature of the molecular sieve is generally 8 ~ 15℃, within this range can work normally, once beyond this ran

Mar 28, 2013

Why does the purification system of molecular sieve sometimes cause water inflow accident and how to solve it?

In front of the molecular sieve purifier, in order to reduce the temperature when the processed air enters the purifier, the whole low pressure oxygen

What are the key points of the small medium pressure air separation equipment after the liquid empty appears?

In order to accumulate the liquid as soon as possible after the appearance of the liquid, we should prepare as much cold as possible and reduce the co

Mar 28, 2013

Why does the high pressure rise not rise high after the distillation column is started?

After the distillation column is started, the main possible reasons why the high pressure does not rise to the designed value are:1) insufficient proc

Mar 28, 2013

Why should the air inlet cam of expansion machine and high pressure air throttle coordinate with each other to adjust, and how to adjust?

For the 50 m 3/h and 150 m 3/h oxygen generator, the compressed air is divided into two routes after going through the first heat exchanger: one is go

How to judge the internal air leakage of piston expansion machine?

When the expansion machine leaks, the efficiency of the expansion machine will decrease. In this way, during normal operation, the pressure must be in

Mar 27, 2013

How does the liquefaction unit liquefaction oxygen and nitrogen, and what role does it play in the oxygen plant?

The liquefaction unit is divided into low pressure liquefaction cycle and medium pressure liquefaction cycle, and the circulation medium can be air or

Mar 27, 2013

What is the working principle of small air separation equipment level and nitrogen discharge valve?

Oxygen and nitrogen discharge valve is used to control the purity of oxygen and nitrogen and low pressure. When the purity of oxygen is lower than the

Mar 26, 2013

What is the main principle of the small air separation plant to shorten the start-up time?

This is because the temperature in the air separation tower in the start-up phase is away from the normal working temperature (-172 ~ -194 ℃) is relat

Mar 26, 2013

Why is the cold box of the air separation plant equipped with respirator?

The cold box of the air separation plant is equivalent to the shell of a low temperature container. Whether it is medium or large air separation plant

Mar 26, 2013

Why does the air separation plant need to fill the cold box with lazy gas during operation?

The cold-keeping (heat insulation) material is filled in the cold-keeping box of the air separation unit, while the interspace between particles of th

Mar 26, 2013

What are the requirements for the purity of high purity oxygen and how to produce it?

Large-scale integrated circuit, television tube, laser communication optical fiber, analysis and test and other high-tech fields require the purity of
