| Abstract: | To reduce the fuel gas consumption,the waste heat of the quench water of ethylene plant is used to preheat the air in the cracking furnance.And the ethylene cracking furnace system in a 460 kt/a ethylene plant of PetroChina Lanzhou petrochemical company is modified by installing a air preheater in the air inlet of the bottom of cracking furnance.The results show that,after modification,the energy consumption of fuel gas has been decreased by 3 kg/t and the benefit is 4 140 000 per year. |
