Using new technologies to extract more than a dozen kinds of high-quality chemical raw materials needed by the market
The ethylene cracking tar comprehensive utilization technology developed by Tianjin Tianda Tianhai Chemical New Technology Co., Ltd. and Shandong Qilong Chemical Industry Co., Ltd., successfully extracted five series of more than ten high-quality chemical raw materials urgently needed from the ethylene cracking tar. High value-added comprehensive utilization of ethylene cracked tar. On May 20th, the 12-ton/year ethylene cracking tar comprehensive utilization device modified and constructed by this technology was used to complete a three-month trial run. The color number of the produced terpenoid petroleum resin was less than 4 and the naphtha content of the petroleum naphtha obtained by distillation was greater than 95. %. According to calculations, the device can bring a profit of 37 million yuan per year to the company.
Ethylene cracking tar is the product of high temperature condensation of raw materials and products in the steam cracking process of ethylene cracking raw materials. According to reports, the composition of ethylene cracking tar is extremely complex, among which the higher contents are: guanidine, formazan and its homologues, naphthalene, methyl naphthalene, ethyl naphthalene, dimethyl naphthalene, and guanidine, fluorene and phenanthrene. The components are all important raw materials for chemical organic synthesis and are currently in short supply in the domestic market.
Previously, China's ethylene tar comprehensive utilization technology has always had the problems of small equipment size, large operating environment pollution, single product variety, poor quality, and low comprehensive utilization of resources. The production technology is based on "extensive" processes that consume large amounts of resources and energy. A large number of ethylene cracked tars are burned after entering the fuel oil market without being processed or simply processed. This not only wastes precious chemical resources, but also causes Environmental pollution.
The comprehensive utilization technology of ethylene pyrolysis tar developed by Tianda Tianhai Co., Ltd., through the development of complete sets of industrialized technologies for the comprehensive utilization of ethylene cracking tar, has reformed and improved the process route, optimized the use of resources and energy, improved product quality, and increased the number of products. Types, to achieve the goal of the scale of ethylene cracking tar comprehensive utilization equipment, product refinement and maximize efficiency. This technology can be used to maximize the comprehensive utilization of ethylene cracking tar. The phthalein resin oil containing naphthalene content ≤ 0.5% and the methylhydrazine resin oil containing naphthalene content ≤ 5% can be used to produce light-colored petroleum resins. A mixture of α,β-methylnaphthalene with a methylnaphthalene content of ≥90% can be used as a raw material for medicines and surfactants, or for the production of MF-type dispersants, etc.; and some heavy oils can be thermally polymerized to produce black resins. The other part can be used as a raw material for the production of carbon black. This project passed the technical appraisal organized by Tianjin Science and Technology Commission last week.
