Air Separatione

Air Purification System

Working principle:
In traditional low temperature air separation, water in the air will freeze and break out at cold temperature and block equipment and pipelines; hydrocarbon (especially acetylene) gather in the air separation device and cause explosion under certain conditions. So before the raw air enters the low-temperature separation process, these impurities all need to be removed through the air purification system filled with the molecular sieve.

Adbent heat:
Physical adsorption is water absorption, and CO2 condensation latent heat is generated, so the temperature before and after the adsorbent is raised.

Regeneration:
Because the adsorbent is solid, its porous adsorption surface is limited, so it cannot be operated continuously. When the adsorption capacity, desorption must be saturated.

Adsorbent:

Activated aumina, molecular sieve, ceramic ball

Ceramic Ball: bottom bed for air distribution. Good bed surface distribution can not be used.

Activated Alumina: the main effect is the preliminary water absorption,

Molecular Sieve: deep water and carbon dioxide absorption.It is important to ensure the CO2 adsorption capacity of the molecular sieve, as water and CO2 are coadsorbed in 13X, and CO2 can ice block the device. Therefore, in the deep cold air separation, the CO2 adsorption capacity of 13X is the key factor.

PSA Nitrogen Generator

AirSeparation2

The raw materials of carbon molecular sieve are coconut shell, coal, resin, pulverized first and combined with the base material, mainly to increase the strength to prevent crushing pulverized material: then activated pores, into the activator at 600-1000 ℃ temperature, commonly used activators are water vapor, carbon dioxide, oxygen and mixed gas. PSA nitrogen separates nitrogen and oxygen by the van der Waals force of carbon molecular sieve, therefore, the larger the molecular sieve than surface area, the more uniform the pore distribution, and the more the number of pores or subpores, the greater the adsorption amount; if the aperture is as small as possible, the van der Waals force field overlaps, which also has a better separation effect on low concentration substances.

Nitrogen generator is a nitrogen production equipment designed and manufactured according to the variable pressure adsorption technology. Nitrogen generator takes high quality imported carbon molecular sieve (CMS) as adsorbent and adopts normal temperature pressure adsorption principle (PSA). Usually use two adsorption towers in parallel, control the inlet pneumatic valve automatically operated by the inlet PLC, alternately pressurized adsorption and decompressing regeneration, complete nitrogen and oxygen separation, to obtain the required high purity nitrogen.

PSA Oxygen Generator

PSA oxygen system has the trend to replace the traditional low temperature air separation device in the medium and small-scale air separation field, due to its low investment , low energy consumption, convenient operation,  The oxygen sieve uses different adsorption velocity of nitrogen and oxygen to make oxygen and oxygen-rich air. For VSA and VPSA devices with lower adsorption pressure, lithium molecular sieve for efficient oxygen production can further improve oxygen production rate and reduce oxygen energy consumption.

Psa Small Medical Oxygen Concentrator

Air is filtered through the inlet filter device before into compressor, then into the molecular sieve tower for oxygen, nitrogen separation. Oxygen passes smoothly through the molecular sieve tower into the fine sieve tower, and nitrogen is adsorbed by the molecules, and is discharged into the atmosphere through the separation valve. After the oxygen further improves the concentration in the fine sieve tower, the flow size is controlled by the flow control valve, then moistened through the wet water tank, and finally flows through the oxygen transfer tube for the user to supplement the oxygen absorption.

JZ molecular sieve can reach the oxygen purity of 92-95%.

Psa Industrial Oxygen Generator

AirSeparation4

Oxygen production system mainly consists of air compressor, air cooler, air buffer tank, switching valve, adsorbent, and oxygen balance tank. After the raw air is removed from the dust particles through the suction port filter, it is pressurized by the air compressor to 3~4barg and enters into one of the adsorption tower. The adsorption tower is filled with an adsorbent, wherein moisture, carbon dioxide, and a few other gas components are adsorbed at the entrance of the adsorbent, and then the nitrogen is adsorbed by a zeolite molecular sieve filled in the upper part of the activated alumina. Oxygen (including argon) is a non-adsorbent component from the top outlet of the adsorbent as the product gas to the oxygen balance tank. When the adsorbent is absorbed to a certain extent, the adsorbent will reach the saturation state, then emptied through the switching valve, the adsorbed water, carbon dioxide, nitrogen and a small amount of other gas components are discharged to the atmosphere, and the adsorbent is regenerated.

Psa Hydrogen Generator

AirSeparation5

The separation and purification of hydrogen gas is one of the earliest fields of industrialization of PSA technology.

The principle of variable pressure adsorption separation gas mixture is that the adsorption capacity of the adsorbent varies with the pressure to different gas components.High pressure adsorption removes the impurities in the raw gas to remove the impurities and extract the pure components.JZ-512H molecular sieve adsorbent changing hydrogen adsorption pressure to separate rich hydrogen gas, which is done through the pressure change of the adsorption bed. Hydrogen is extremely difficult to adsorb, other gases (can be called impurities) are easily or easily adsorbed, so that hydrogen-rich gas will produce under conditions close to the inlet pressure of the treated gas. Impurities are released during desorption (regeneration), when the pressure gradually drops to the desorption pressure.

The adsorbent tower is an alternating adsorption, mean pressure and desorption process to achieve continuous hydrogen output. Hydrogen-rich gas enters the system, under a certain pressure. Hydrogen rich gas from bottom to up through the adsorption tower filled with proprietary adsorbent, CO / CH4 / N2 stays on the surface of the adsorbent and H2 penetrates the bed as the adsorption component. Outside the hydrogen output boundary of the product collected from the top of the adsorption tower. When the adsorbent in the bed is saturated by CO / CH4 / N2, hydrogen rich switches to other adsorption towers. In the process of adsorption-desorption, the adsorption tower still has a certain pressure product hydrogen, using this part of pure hydrogen to the other equal pressure and washing, which not only uses the residual hydrogen in the adsorption tower, but also slows down the pressure rise speed in the adsorption tower, also slows down the fatigue in the adsorption tower, effectively achieve the purpose of the hydrogen separation.
