New ion liquid alkylation technology is used

The world's first industrialization device driving
by China's Tohoku Engineering Co., Ltd. and China Petroleum University jointly developed composite ion liquid alkylation technology recently in China Petroleum Harbin Petrochemical Co., Ltd. 150,000 tons / year alkylation device successfully put into use. The world's first set of ion liquid alkylation industrial plant is currently operating steadily, the output of the octane value of 96, product indicators to meet the design standards.
This is another achievement of ion liquid alkylation technology after the industrialization test in Deyang, Shandong Province, and a new breakthrough in carbon tranylation technology has been made, providing technical support for the upgrading of six gasolines in China .
, party secretary of the Northeast Engineering Company, introduced that with the continuous increase of national environmental protection efforts, the oil upgrade put forward higher quality requirements. Isobutane and isobutane-based reaction is a very important process for the production of clean high octane gasoline, which is of great significance to solve the problem of heavy oil catalytic cracking as the main production of clean fuel in China. Ion liquid is a liquid state of salt, with low steam pressure, low corrosion, non-combustible characteristics, ion liquid alkylation technology and traditional hydrofluoric acid, sulfuric acid method, the advantages of safety and environmental protection is obvious, low requirements for equipment materials, simple reactor structure, low investment and maintenance costs, low land area, mild reaction conditions, is currently the world's leading alkylation advantage technology.
At the same time, the alkylated oil produced by the alkylation reaction of isobutane and olefins in liquefied gas has the characteristics of low sulfur, no aromatics, no olefins, low steam pressure and high octane, and is a high-quality gasoline part of high grade gasoline. And when the promotion of ethanol gasoline led to the shutdown of MTBE device, the ether containing isobutene before carbon four can be directly used as raw material for ion liquid alkylation device, which is another major advantage of the technology.
, the Northeast Engineering Company aimed at the forefront of research and development of refining process technology, examined a variety of alkylation technology, and finally joined forces with China Petroleum University to jointly develop ion liquid alkylation technology and industrialization applications. In this process, the project team in accordance with the actual situation of project construction and installation application, and constantly optimize the process design, research and development of technical products, one after another to form the outflow - ion liquid static separation and efficient fusion technology, acid-containing organic gas alkali washing - washing integration technology, ion liquid scum in ion liquid - There are 4 technical secrets such as static subsidon separation technology, alkylated oil organchlorine removal and re-angry harmless emission technology in gasoline system, and 3 proprietary equipments such as high-efficiency fusion separators, static separators and flash hydrocarbon purifiers have been independently developed.
Du Yunxuan introduced, Ha Petrochemical 150,000 tons / year alkylation plant by the general contract construction of the Northeast Project, from the basic design approval to the success of driving, it took only 9 months. During this time, technicians crouched on site, with 67 technical optimizations, ensuring a successful one-time drive.
