Description:
Pressure swing adsorption (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species' molecular characteristics and affinity for an adsorbent material. It operates at near-ambient temperatures and differs significantly from cryogenic distillation techniques of gas separation.
Specific adsorptive materials (e.g., zeolites, activated carbon, molecular sieves, etc.) are used as a trap, preferentially adsorbing the target gas species at high pressure. The process then swings to low pressure to desorb the adsorbed material.
Pressure swing adsorption processes rely on the fact that under high pressure, gases tend to be attracted to solid surfaces, or "adsorbed". The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or desorbed. PSA processes can be used to separate gases in a mixture because different gases tend to be attracted to different solid surfaces more or less strongly.
If a gas mixture such as air, for example, is passed under pressure through a vessel containing an adsorbent bed of zeolite that attracts nitrogen more strongly than it does oxygen, part or all of the nitrogen will stay in the bed, and the gas coming out of the vessel will be enriched in oxygen. When the bed reaches the end of its capacity to adsorb nitrogen, it can be regenerated by reducing the pressure, thereby releasing the adsorbed nitrogen. It is then ready for another cycle of producing oxygen enriched air.
This is the process used in medical oxygen concentrators used by emphysema patients and others who require oxygen-enriched air to breathe.
Using two adsorbent vessels allows near-continuous production of the target gas. It also permits so-called pressure equalisation, where the gas leaving the vessel being depressurised is used to partially pressurise the second vessel. This results in significant energy savings, and is common industrial practice.
Features:
1. It operates quickly, qualified Hydrogen can be made immediately
2.The machine can fully automatic operate, without workers during the whole course
3. High efficiency molecular sieves filling, more compress, more solid, more lifelong
4. Pressure, purity, capacity can be made, to meet different customers needs.
5.Perfect structure, advanced procedure, stable@safety, little investment, lower consumption
1. Ability to produce ultra-high purity (99.9 to 99.999%) Hydrogen H2 with high recovery rates. Standard process modules designs deliver ease of construction, reduced schedule risk, and ultimately lower project costs.
2. Safe, reliable and guaranteed system performance.
3. PSA systems that perform the intended separation with the use of commercially proven adsorbents with the ability to remove multiple impurities such as hydrogen sulfide, hydrocarbons, carbon oxides, and water from crude H2 feed streams.
4. Experienced project teams with the know-how for executing the PSA project scope on-time, and the understanding of project activities for integration of the PSA system with other plant equipment (compression, product H2 supply systems, fuel systems), communications with plant control systems, HAZOP reviews, and the supply of advisory services for construction and plant start-up.
