Honeywell advanced technology helps the hydrogen purification of Zhejiang satellite propylene unit

des Plaines, Illinois, USA. on December 9, 2019, Honeywell announced today that Zhejiang satellite adopts intelligent feedback computing star Petrochemical Co., Ltd. (hereinafter referred to as Zhejiang satellite) to select Honeywell UOP polybed pressure swing adsorption (PSA) unit to supply high-purity hydrogen for its integrated refining and chemical unit. The unit uses UOP C3 oleflex technology to produce polymer grade propylene, which is the second oleflex propane dehydrogenation unit integrating UOP PSA technology in China

in intermediate cars

in view of the growing domestic demand for propylene, Zhejiang satellite has invested in the construction of a second C3 oleflex unit. The unit uses PSA technology to improve the purity of hydrogen to meet the refining demand. As a leading technology supplier in the oil and gas industry, Honeywell UOP will not only provide technology licenses, but also provide services, equipment, catalysts, adsorbents and other supporting services

in the past five years, we have continuously deepened cooperation with Zhejiang satellite, built new petrochemical facilities around oleflex technology, and greatly improved operational flexibility and production reliability. Liumaoshu, vice president and general manager of Honeywell characteristic materials and Technology Group in Asia Pacific region and vice president and general manager of Honeywell UOP China region, said that the introduction of PSA technology can help Zhejiang satellite further improve operational reliability and ensure stable and continuous access to high-purity hydrogen sources

psa process adopts UOP's patented adsorbent, which can remove impurities in hydrogen containing gas under high pressure, recover hydrogen, and the structural capacity of the portal UTM experimental machine can reach 1000~135000 lb, purified to more than 99.9%, so as to meet the refining demand

in addition to recovering and purifying hydrogen from reforming furnace and oil refining waste gas, the polymed PSA system can also use other gases (such as ethylene waste gas, methanol waste gas and partial oxidation syngas) to produce hydrogen. Polyfed PSA system is a skid mounted modular device, which integrates hardware equipment, adsorbent, control system and embedded process technology. It can realize rapid and efficient installation, so as to effectively reduce costs and shorten downtime

since its inception in 1966, UOP has continuously improved PSA technology, continuously upgraded adsorbents, strengthened circulation configuration, improved process and device design, and adopted more reliable control systems and equipment. Up to now, Honeywell UOP has successfully installed more than 1100 sets of PS environmental protection concept in more than 70 countries and regions around the world. As a mature technology, PSA has dozens of successful cases of large-scale devices worldwide

Wanhua chemical is the first in China to use Honeywell UOP PSA technology for its oleflex propane dehydrogenation unit to produce polymer grade propylene

Zhejiang satellite Petrochemical Co., Ltd. is the leading global top five acrylic acid manufacturer in China and the first private listed enterprise in China to form an integrated pattern of C industry with propane as raw material. The company integrates R & D, production, sales and logistics, covering more than 10 categories of products from propylene, polypropylene, acrylic acid, high-purity acrylic acid, to acrylate, polymer lotion, super absorbent resin and so on
