HS-ⅡCracking Furnace In Ethylene Installment Application

Ethylene is a measure of a country’s chemical production level symbol, since twentieth Century since 60 time, our country has built23 sets of ethylene plant. In recent years, the country vigorously promote energy-saving emission reduction, reducing the comprehensive energy consumption of ethylene plant is the key task of reducing state. Jilin petrochemical ethylene plant in order to reduce the unit comprehensive energy consumption, a new cracking furnace (F-1010), in order to improve the competitiveness of the industry in china. This article focuses on the F-1010cracking furnace is able to adapt to the current raw material diversity requirement, by reducing furnace wall surface temperature, exhaust gas temperature and the use of coking inhibitor, air preheater, and a domestic fan and" symmetrical U type" furnace tube, so that the energy consumption of the unit to reduce 15kg standard oil/tons of ethylene, and Realization of cracking furnace of large equipment in china. Through the use of coking inhibitor, cracking furnace operation cycle from 45 days to55 days, to realize the long period operation of cracking furnace; at the same time, F-1010cracking furnace adopts domestic advanced DCS control system, the pyrolysis furnace automatic, cascade cast rate reached 75%, with a rate of 100% interlock. F-1010cracking furnace through a period of performance, has reached international advanced level of technology of cracking furnace, cracking furnace for domestic large scale, security, stability, long period run laid a solid foundation.
