CN104774638A 一种用于加工劣质渣油可控弹丸焦出现的方法 无效 - 驳回

一种用于加工劣质渣油可控弹丸焦出现的方法
摘要：
一种用于加工劣质渣油可控弹丸焦出现的方法，采用延迟焦化生产装置，延迟焦化生产装置包括焦炭塔，焦炭塔的进料温度为497～503℃，塔顶压力0.13～0.15MPa，油气线速度0.07-0.08m/s；劣质渣油是指加工密度≥972kg/m3、残炭值≥21.4%、沥青质含量≥12.3%、镍钒含量≥100μg/g的渣油。本发明对于原料性质非常差劣、以及反应温度、反应压力、循环比操作参数都十分苛刻，也能有效避免弹丸焦出现，从而确保延迟焦化装置生产安全，并能提高目标产物液体收率、降低能耗、获得最大的经济效益。
摘要（英）：

A method for avoiding shot coke generation in inferior residuum processing adopts a delayed coking production apparatus, the delayed coking production apparatus comprises a coke tower, the charging temperature of the coke tower is 497-503DEG C, the tower top pressure is 0.13-0.15MPa, and the oil gas linear velocity is 0.07-0.08m/s; and the inferior residuum is residuum with the processing density of 972kg/m<3> or more, the carbon residue of 21.4% or more, the asphaltene content of 12.3% or more and the nickel vanadium content of 100[mu]g/g or more. The method has very strict requirements on the properties of a raw material, the reaction temperature, the reaction pressure, the cycle ratio and other operation parameters, and can effectively avoid shot coke generation in order to ensure the production safety of the delayed coking apparatus, improve the liquid yield of target products, reduce energy consumption and obtain largest economic benefit.
