摘要： A process for making a light hydrocarbonaceous liquid in a delayed coker comprising:(A) providing a hydrocarbonaceous feed to the coke drum and heating the feed to a temperature of about 800.degree. F. to about 1200.degree. F. to provide an intermediate product; and(B) introducing said intermediate product into the coke drum, operating the coke drum to convert the intermediate product to a final comprising light liquid and coke, and separating the light liquid from the coke;step (A) being conducted in combination with either step (A) (i) or step (A) (ii);Step (A) (i) comprising maintaining the feed during step (A) in an enclosed space and subjecting the feed to a pressure that is at least about 500 psig and is sufficient to maintain the specific gravity of the contents of the enclosed space at least about 0.05 to convert said feed to said intermediate product, the intermediate product containing fractions having a lower boiling point than the initial boiling point of the feed and/or a higher boiling point than the final boiling point of the feed, then reducing the pressure on the intermediate product below about 500 psig prior to step (B);step (A) (ii) comprising contacting the intermediate product from step (A) prior to and/or during step (B) with at least one preheated stripping gas and dissolving at least part of the intermediate product in the stripping gas.
摘要翻译：一种在延迟焦化器中制造轻质含烃液体的方法，包括：（A）向焦炭鼓提供烃质进料并将进料加热至约800°F至约1200°F的温度以提供中间产物; 和（B）将所述中间产物引入焦炭鼓中，操作焦炭鼓以将中间产物转化成包含轻质液体和焦炭的最终产物，并将轻质液体与焦炭分离; 步骤（A）与步骤（A）（i）或步骤（A）（ii）组合进行; 步骤（A）（i）（i）包括在步骤（A）期间将进料保持在封闭空间中，并使进料经受至少约500psig的压力并足以将封闭空间的内容物的比重维持在至少约0.05以将所述进料转化成所述中间产物，所述中间产物含有比所述进料的初始沸点低的沸点和/或比所述进料的最终沸点高的沸点，然后降低所述压力在步骤（B）之前约500psig下的中间产物; 步骤（A）（ii）包括在步骤（B）之前和/或步骤（B）期间使来自步骤（A）的中间产物与至少一个预热的汽提气体接触并将至少部分中间产物溶解在汽提气体中。
