一、注水方案的提出在裂化炉管内注水以减少炉管结焦,在国外已经是成熟的经验,但在国内以往还未试验过。据介绍罗马尼亚炼油厂采用注水方法,重油炉管流量65米~3/时,注水量350—400公升/时,炉管出口温度485℃,开炼周期由注水前的25天延长到40天。石油技术情报1956年第4期报导,苏联在设计Γ-18/2型接触焦化装置时,为了证明所采用的重油破坏蒸馏炉是否会严重结焦,也采用了向炉管注水的方法,
First, the proposed water injection program In the cracking furnace tube water to reduce the furnace tube coke, is already a mature experience in foreign countries, but in the country has not been tested in the past. It is reported that the Romanian refinery using water injection method, heavy oil furnace tube flow of 65 m ~ 3 / hour, water injection volume of 350-400 liters / hour, the tube outlet temperature of 485 ℃, open cycle from 25 days before watering to 40 days. Petroleum Technical Intelligence No. 4 of 1956 reported that in designing the Γ-18/2-type contact coking unit, the Soviet Union used a method of injecting water into the furnace tube in order to prove whether the heavy oil destruction distillation furnace used for the Soviet Union would seriously coking,
