The deflagration of the oxygen compressor will cause great harm to the safe operation of the air separation equipment and the personal safety of the operators. Each air separation user should attach great importance to the safe operation of the oxygen compressor to prevent the occurrence of the deflagration accident.

The design of the internal structure of the adsorber: the design of the internal structure of the adsorber includes the determination of the bed layer and various auxiliary structures, such as the design of the upper and lower filter, the guide valve, the pressing mechanism, the gas distribution device and so on. The adsorber can usually be divided into single bed and double bed, and the structure is shown in figure 3. Both the upper and lower vent of the two structures are equipped with filter and gas distributor. The single-layer bed structure is equipped with a screen hole plate and a cylinder compressing device on the molecular sieve adsorber. When the adsorber is working, the cylinder piston generates a lower thrust by differential pressure and compresses the molecular sieve through the screen hole plate, it avoids the phenomena that the molecular sieve is boiling and flowing and the filter screen is damaged due to the excessive airflow, thus prolonging the life of the molecula...

Before installation of piping for liquid air separation plant, oxygen piping should be subjected to strict acid cleaning and degreasing in accordance with the national standard "Safety Technical Regulations for the Production of Oxygen and Related Gases by Deep Freezing", and then blown clean with dry air or nitrogen without oil.   When the oxygen pipeline has not been put into operation for a long time after installation and construction, it should be protected with dry gas to prevent hu...

1. Adhere to the electrical professionals to work with certificates, non electrical professionals are not allowed to replace or repair any electrical components. 2. Establish the temporary electricity inspection system, inspect and irregularly inspect various lines and facilities on site according to the temporary power management regulations, and archive the inspection and spot check records. 3. The inspectors and operators must wear insulating rubber shoes and gloves according to the regulations; they must use special insulating tools for electricians. 4. The temporary distribution lines must be erected according to the specifications. The overhead lines must be insulated wires, plastic flexible wires, bundles of overhead laying and surface laying along the ground. 5. The erection and use of temporary electricity on the construction site must comply with the provisions of technical code for safety of temporary electricity on construction site (JGJ46-88). 6.

How to deal with sediments generated in the low-temperature vessels and pipelines of the air separation equipment fractionation tower system?

properly based on its adsorption temperature curve If the air pre-cooling system is working properly, the temperature of the air into the molecular sieve purifier will not change and the adsorption temperature curve is basically a straight horizontal line. The temperature of the air out of the adsorber is slightly higher than the inlet temperature due to the exothermic effect of adsorption, and is also...

In the temperature of the forward air into the cooler (hot end temperature, related to the cooling effect of the last cooler of the air compressor or nitrogen water precooler) and the temperature of the return air into the cooler (cold end temperature, under the condition that the temperature of the heat exchanger such as the outlet supercooler and the liquid purifier is not changed, the temperature difference between the thermal end and the temperature difference between the cold end of the refrigerator (both refers to the difference between the temperature of the forward air and the reflow gas participating in the switching) is interdependent. If the hot end temperature difference, cold end temperature difference will is too small; the hot end temperature difference is too small, cold end temperature difference will is too large. This is decided by the cooling balance of the positive and return gas of the cooler. When the ratio of return flow to positive flow volume is larger than...

Nitrogen is the main component of air in the universal pressure conversion and adsorption equipment. It is colorless, odorless, non-toxic and non-combustible gas under room temperature and atmospheric pressure, and its boiling point is-195.8 ℃, its chemical property is not active. In addition to synthetic ammonia, nitrogen is usually used as protective gas in industries such as metallurgy, chemical industry, coal, food, medicine, electron, magnetic material, transportation, heat treatment, tire, thermoelectricity, aviation, etc. Special pressure conversion nitrogen absorption equipment for petroleum and petrochemical industry chemical industry is the industry with the largest application of nitrogen air separation equipment. Currently, the most widely used one is: PVC, with a purity of 99.5% and a large flow rate. Polypropylene (PE) has a purity of 99.9% and a large flow rate. The application of nitrogen in this product is divided into two parts. One is that 99.9% nitrogen (small am...
