4A Molecular Sieve Desiccant Zeolite Auxiliary For Natural Gas Desulfurization Denitrification

Product Description of 4A Molecular Sieve Desiccant

4A molecular sieve is an alkali metal aluminosilicate, the chemical formula is Na2O.AI2O3.2SiO2.9/2H2O, the pore size is 4A, and it can absorb water, NH3, H2S, sulfur dioxide, carbon dioxide, C2H5OH, C2H6, C2H4 and other critical diameters not greater than The molecule of 4A does not adsorb Tianke molecules (including propane) with a diameter larger than 4A. The selective adsorption performance of water is higher than that of any other molecules. It is one of the largest molecular sieve varieties used in industry and is widely used in the drying of gases and liquids. , can also be used for the refining and purification of certain gases or liquids, such as the preparation of nitrogen.

Ion transfer performance, water softening function
Each oxygen atom in the 4A molecular sieve framework is shared by two adjacent tetrahedra. This structure forms a large crystal cavity that can be occupied by cations and water molecules. These cations and water molecules have greater mobility, allowing for cation exchange and reversible dehydration. 4A molecular sieve conducts ion exchange with aluminum ions on the framework, and each aluminum ion has a negative charge, which can not only bind sodium ions, but also bind other cations. Calcium and magnesium ions can enter the large crystal pores occupied by the original sodium ions and replace the sodium ions in the 4A molecular sieve, that is, the sodium ions in the 4A molecular sieve can undergo ion exchange and can be combined with Ca2, Mg2 ions in hard water. The exchange achieves the purpose of softening the water quality.
The speed of 4A molecular sieve binding calcium and magnesium ions is slower than that of sodium tripolyphosphate, and its binding ability with magnesium ions is weak. 4A molecular sieves can easily remove a small amount of harmful heavy metal ions (such as Pb2, Cd2, Hg2) from aqueous solutions, which is of great significance for water purification.

Xi'an Lvneng Purification Technology Co., Ltd., was relocated to Xi'an from Dalian in November 2004. With more than 20 years of management and development, it becomes a key manufacturer of the special type molecular sieve in China, specializes in molecular sieve, activated alumina, and other industrial desiccants.

Xi'an Lvneng Purification Technology Co., Ltd., relying on the professional background of molecular sieve absorbent research and development, production and operation for nearly 30 years have rapidly and steadily developed the foreign markets. In September 2012, the company settled in the Weibei industrial area of Xi'an, with a newly built factory of nearly 8,000 square meters, covering an area of more than 10 mu, with nearly 70 employees, 4 technical researchers, perfect inspection equipment and the technology research & development was in the forefront of the industry. With the completion of the new plant, nearly ten million yuan was invested in the production equipment and the production capacity reached 8,000 tons and its output value has reached over 50 million for two consecutive years. Therefore, it can better meet the sales and operation needs of enterprises.

Xi'an Lvneng Purification Technology Co., Ltd with leading technology and excellent quality as its development objective for many years, has worked closely with Dalian Institute of chemical physics, Chinese Academy of Sciences, Xi 'an institute of high voltage electrical appliances, electrical bureau of machinery industry department, northwest chemical engineering institute, Changqing institute of chemical technology, Daqing petrochemical company and other units to overcome various technical difficulties and steadily improve product quality.

The adsorbent products such as molecular sieve and alumina are widely used in petrochemical, CNG, LNG, industrial gas, compressed air, coal chemical, air separation, refrigeration and construction industries. In particular, with the industrial transformation of the country and the innovation of global industry 4.0, the drying and purification of industrial power gas depend on the upgrading of industrial automation, especially the molecular sieve desiccant.

After 20 years' development in the market, the enterprise still becomes an excellent supplier to a large number of state-owned enterprises, such as Changqing oilfield, Tuha oilfield, Liaohe oilfield, Yanshan petrochemical company, Qingyang petrochemical company, Maoming petrochemical company, China aviation industry group, China shipbuilding industry group and so on. Meanwhile, more than 70% of the adsorbent fillers used in the dehydrated sheath of CNG gas stations in Xinjiang, Shandong, and Hebei regions are our products. In terms of new market development, Xi'an Lvneng Purification Technology Co., Ltd develops foreign trade rapidly and stable on the basis of the strong domestic trade market.

Through Alibaba (China), Kompass (France), Global Sources (the United States), Tendata (Europe), Avention(Europe) and other foreign trade platforms, we have developed a wide range of foreign customers. Currently, our customers are all over Asia, Europe, North America and South America. Alstom (France), Xebec (Canada), Atlas Copco (USA), Danfoss (Denmark), Zarrin Toor Felez (Iran), Saral Azar (Iran) Bhogart LLC (USA), Socane (France), Petro Kimya Akam (Iran), Atlas Caspian (Iran), HD Trading Company (Iran), and Seraj Gostar (Korea), Bioversity (India), etc. Under the efforts of the foreign trade team, the sales revenue of 1.6 million us dollars per year was realized on average in three years, and the special fund of foreign trade subsidy from the provincial department of commerce was obtained for two consecutive years.

Inherit the past and forge ahead into the future, as northwest China's biggest molecular sieve adsorbent manufacturer, leading technology, excellent quality, customized service is our tenet, through the industry-leading new production line, mechanization degree is maximum improved, make our enterprise to adapt to the market and service market better. Thus achieve the sustainable and steady development of enterprises, casting the next brilliant enterprises.
