Effect of activated alumina

Modern gas purification activated alumina, water vapor and some of the liquid has the ability to selective adsorption. After removing the water saturation adsorption regeneration can be heated at about the recovery 175-315 ℃.regeneration of molecular sieves can be repeated rehabilitation. In addition to use as a desiccant, it can also adsorb vapors from contaminated lubricating oxygen, hydrogen, carbon dioxide, natural gas or the like. And are useful as catalysts and catalyst supports, and chromatography carrier. Modern water purification activated alumina is white spherical porous particles, particle size uniformity, smooth surface, high mechanical strength, moisture absorption, no swelling maintain the status quo does not crack after absorbing water, non-toxic, odorless, insoluble in water, ethanol, fluoride has a strong adsorption, mainly used in high fluoride areas of fluoride in drinking water.

About natural gas

Adsorption equipment to use more natural gas dehydration fixed bed adsorption column. In order to ensure continuous production of dry natural gas to be cyclic operation, and to use a plurality of adsorption towers in parallel. Adsorbed amount and form of the tower, ranging from two to more than one alternate. In each adsorption tower, the cycle of three different functions or function must alternate. These three cycles are: adsorption or drying cycle, the heating or recycling, the cooling cycle.

pressure swing adsorption molecular sieve is a molecular sieve having a function of a mixed gas of selective adsorption, the adsorption capacity with temperature and pressure changes. Typically oxygen Pressure swing adsorption technology air separation unit adsorption bed must contain two steps; adsorption and resolution. In order to obtain a continuous product gas, usually oxygen apparatus are means more than two adsorbent beds, and from the perspective of energy and stability, in addition to setting the necessary additional steps. Usually go through each bed adsorption, release the pressure, evacuation or decompression regeneration, replacement and rinse the equalizing boost other steps, periodically repeat the operation. At the same time, each adsorbent bed, respectively, at different steps, time switch under PLC control, so that the bed several coordinated operations on the pace of practice is staggered, so that the pressure swing adsorption system can run smoothly, continuous access to the product gas .

zeochem molecular sieves

Zeolites molecular sieve having a pore size of sub-nanometer pore uniform, high specific surface area (up to 1000 m2g-1, the vast majority of inner pore surface area) and a unique surface electric field, show and activated carbon, silica gel, activated alumina, and other conventional adsorbent different adsorption properties, zeolite polar molecules exhibit specific affinity, but also has the unique ability to screening molecules. Molecular sieve adsorbent in petrochemical industry has been widely used, has a high separation effect, the operation is relatively simple, good economic advantages.

Compare activated alumina and molecular sieve adsorption of water features seen: Activated alumina for higher air moisture adsorption capacity is relatively large, but with reduced air moisture adsorption capacity drops quickly. The molecular sieve even at very low water content, the same has strong water absorption. Also, aluminum plastic desorption water easily, can reduce the regeneration temperature; it heats of adsorption of water smaller than the molecular sieve, the air temperature rise is small, is conducive to the rear of the molecular sieve adsorption of CO2; and aluminum plastic also has acid resistance, molecular sieve can play a protective role. Based on these characteristics, some purifiers structure with a double bed, air purifier into the I = I side, put a layer of activated alumina. It is the first most of the water contained in the air cleared, and the molecular sieve is mainly used to remove carbon dioxide, acetylene and other hydrocarbons. Using double adsorption bed, you can extend the use of purification time. Carrying activated alumina - Zeolite bunk bed test results: purifier effective working time extension of 25% to 30%.
