November 1, the reporter was informed that the Dushanzi Petrochemical Company Ethylene two joint workshop on the 7th after the completion of scorch cracking furnace put into operation after the continuous operation of the furnace for 104 days, creating the longest domestic liquid phase furnace of similar devices operating cycle record .
It is understood that with an annual output of 220,000 tons of monoliths, with an annual output of 1 million tons of two sets of ethylene plant, respectively, the introduction of the United States LUMMUS (Lummus) and Germany LINDE (Linde) technology, including an annual output of 220,000 tons ethylene plant on the 7th Cracking furnace for 30,000 tons SRT-Ⅵ cracking furnace, naphtha is currently the cracking of raw materials, feed volume of 29.31 tons per hour.
Since the beginning of this year, SINOPEC actively targeted the domestic and international advanced standards and conducted long-term operation of cracking furnaces to replace old-style furnace tubes with relatively advanced furnace tubes. In the same circumstances, the time for materials to stay in furnace tubes was shortened , To reduce coking, thereby extending the operating cycle.Development of this year, cracking furnace care race, all-round 24-hour care, and further regulate the cracking furnace switching operation, the preparation of a pyrolysis furnace nitrogen oxides control program, regulate the control of the cracking furnace to achieve the best Operating conditions.
After special care and energy saving of cracking furnace, the energy efficiency of monolithic petrochemical increased by 0.65% in the first 8 months.
