    摘要: The morphology of petroleum cokes produced by the delayed coking of feeds produced from extra-heavy crude sources such as those from the Venezuela Orinoco Heavy Oil Belt can be controlled to produce a less dense coke which is less likely to inflame in the coke pit or in subsequent handling. An aqueous solution of an alkali metal or alkaline earth metal carbonate salt when added to a feed of this type which would normally produce a dense coke product is effective to produce a quenchable coke product of lower density and higher porosity, usually in compact, granular form permitting it to be readily discharged from the drum.

    摘要: Petroleum cokes derived from extra-heavy crude sources can be made more amenable to quenching by adding water or a water/light oil mixture to the coker feed downstream of the furnace. The coke product resulting from this addition of normally volatile liquids to the hot coker feed is still relatively dense but is more friable and usually is in a compact, relatively free-flowing, granular form. The coke is more amenable to uniform quenching in the drum and so can be cut and discharged with a reduced risk of eruptions and a reduced risk of fires in the coke pit or when the coke is subsequently handled and transported.
