PSA technology development and characteristics of pressure swing adsorption (referred to as PSA) technology in the industry in recent decades the Pressure swing adsorption technology rise of new gas separation technology. The basic principle is to use gas component adsorption characteristics differences on solid adsorption materials for gas separation process is achieved by pressure changes periodically. PSA technology in China's industrial regeneration of molecular sieves applications have ten years of history, because of its low energy consumption, simple process, pressure swing adsorption gas separation as a new development of technology and its application. At the same time compared with conventional gas separation method, pointed out the pressure swing adsorption technology has a significant feature of low energy consumption, low investment, easy operation, highly competitive market. Commonly used PSA oxygen process generally includes the following steps, adsorption, emptying, washing, grading and filling pressure. pressure swing adsorption molecular sieve  There are currently using two PSA, three PSA, PSA and four vacuum pressure swing adsorption (VacuumSwing Adsorption, referred VSA) technology. Depending on the conditions of the adsorption bed regeneration regeneration can be divided into atmospheric and vacuum regeneration, the latter Known as vacuum swing adsorption (VSA). View Details

A natural gas transmission pipeline pressure changes last paragraph For conventional long distance gas pipeline design, calculation by the last paragraph of the last paragraph of Pressure swing adsorption technology the length of the storage capacity, the last compressor station maximum allowable working pressure and the impact of urban distribution pipeline network required minimum working pressure. Therefore, in the design of gas pipelines, according to actual needs, take into account all the functions and the last paragraph of the pipeline, especially on the city peaking. In the last paragraph of factors affecting gas pipeline capacity in the last paragraph and last grace molecular sieves paragraph of the pressure pipe length changes have played a decisive role, and length of the pipeline is often hampered by the physical environment, so we focus on the changes in the last paragraph of pressure pipeline. Pressure changes in the calculation of the last paragraph on the need to use the pressure ratio and pressure ratio function formula φ (). Calculate pressure swing adsorption molecular sieve  the average pressure is as follows: 5-in can be drawn from the above ratio as a function of pressure in order to facilitate the calculation formula, made according to the type of φ () function table. Therefore, to calculate φ by pipeline capacity and the last paragraph of average pressure () later, you can have a table check out the pressure ratio, calculated according to the last paragraph and then switched on, end pressure requirements.

Desulfurization mainly to prevent combustion of natural gas produces sulfur dioxide and other air pollution; dehydration is to prevent natural gas pipeline process (high pressure) to form crystalline hydrates clogged pipes; mainly off Pressure psa molecular sieve swing adsorption technology the hydrocarbons and natural gas condensate in order to put two and two isolation of the compound out of two or more carbon atoms (such as LPG, butane (lighter component composition)) used for other more useful ways, in addition also to prevent the formation Pressure swing adsorption technology of droplets in a cryogenic gas transportation process, affecting transmission efficiency.Dehydration method is usually used are solvent and solid desiccant dehydration assay. Lower solvent absorption method has an molecular sieves 5a  advantage of the equipment investment and operating costs, is more suitable for large-volume high-pressure natural gas dehydration, which is the most widely used solution of triethylene glycol dehydration process, but the limited depth of dehydration, the dew point depression is generally not exceed 45 ℃. Solid desiccant dehydration after the dry gas adsorption method, the dew point is below -50 ℃. View Details

Adsorbents which can efficiently adsorb some of the solid material from the gas component or a liquid. Adsorbents generally have the following characteristics: a large specific surface area, suitable pore structure and surface structure; strong adsorbate on the adsorption capacity; generally do not react chemically with the adsorbate and media; psa oxygen generator molecular sieve  easy manufacture, easy to regenerate; good mechanical strength. Adsorbents can pore size, particle shape, chemical composition, surface polarity classification, such as coarse holes and pore adsorbents, powder, granular, strip adsorbents, carbon and oxide sorbents, polar and non-polar adsorbent.Common carbonaceous adsorbents have psa molecular sieve  a variety of activated carbon adsorbent as raw materials and metals, non-metallic oxide adsorbents (such as silica, alumina, zeolite, a natural clay, etc.). The main indicators of adsorbent are: adsorption capacity of different gaseous impurities, wear rate, bulk density, specific surface area, crush strength and the like. For filtering gas, refined oil and vegetable oil, to prevent viruses and fungi, as well as the recovery of natural gas in petrol colored sugar and other substances such as bleaching. View Details

Second, relying on abundant natural gas resource base, natural gas drying  good planning of the overall system, strengthen the natural gas infrastructure, increased research efforts to improve China's natural gas production and development technology, and strive to make China's natural gas market, the middle and lower reaches of the production, supply, pin coordinated development. Third, natural gas prices gradually into line with international prices. Natural gas as a cleaner, better quality, more economical clean energy and chemical raw materials, has been recognized by the international community, to develop natural gas in line with world trends in energy  development. Vigorously develop the natural gas business, but also our efforts must be made to meet gas demand, natural gas separation  therefore, from the perspective of the requirements of China's social and economic development, the development of the natural gas business is a strategic project.
