摘要: A fluid coking unit for converting a heavy oil feed to lower boiling products by thermal has a centrally-apertured annular baffle at the top of the stripping zone below the coking zone to inhibit recirculation of solid particles from the stripping zone to the coking zone. By inhibiting recirculation of the particles from the stripping zone to the coking zone, the temperatures of the two zones are effectively decoupled, enabling the coking zone to be run at a lower temperature than the stripping zone to increase the yield of liquid products.

摘要翻译: 用于通过热将重油进料转化为较低沸点产物的流体焦化装置在焦化区下方的汽提区的顶部具有中心孔环形挡板,以阻止固体颗粒从汽提区再循环到焦化区。 通过抑制颗粒从汽提区再循环到焦化区,两个区域的温度被有效地解耦,使得焦化区能够在比汽提区域低的温度下运行,以增加液体产物的产率。
