High Affinity Adsorbent 3A Molecular Sieve Desiccant For Unsaturated Hydrocarbon Material Dehydration

Product Description of 3A Molecular Sieve Desiccant

Selective adsorption based on molecular polarity, unsaturation and polarizability
Molecular sieves have high affinity for polar molecules and unsaturated molecules; Among nonpolar molecules, they have higher selective adsorption advantages for molecules with high polarizability. In addition, the lower the boiling point of the molecule, the less likely it is to be adsorbed by the molecular sieve.

Molecular sieves have high affinity for H2O, NH3, H2S, CO2 and other polymer polarities, especially for water at low partial pressure (even lower than 133 PA) or low concentration, high temperature (even higher than 100 ℃). It still has high adsorption capacity under adverse conditions.

Molecular sieve is the only available high temperature adsorbent. At 100 ℃ and 1.3% relative humidity, the molecular sieve can absorb 15% water. Therefore, at higher temperatures, molecular sieves can still absorb a considerable amount of water.

The cracked gas generally contains 400-700ppm of water, which will form ice during cryogenic separation. In addition, under high pressure and low temperature conditions, water can also form white crystalline hydrocarbon hydrate with low-carbon alkanes (such as CH4, C2H6 and C3H8). The crystals of ice and hydrocarbon hydrate can cause blockage of pipelines and equipment, and even cause shutdown.

Therefore, the petroleum cracked gas must be deeply dehydrated and dried before cryogenic separation to reduce the water content in the cracked gas to less than 5ppm (i.e. its dew point is less than - 60 ℃).

At present, the most ideal deep drying adsorbent recognized and commonly used in China is 3A zeolite molecular sieve. Because it only adsorbs water in cracked gas and does not adsorb large hydrocarbon molecules (such as C2H6, C2H4, C3H8, C3H6, etc.), it can avoid coking of olefin compounds in the molecular sieve channels, thus prolonging the service life of the adsorbent.

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.
