    • A device for use in separating debris from a flowing stream which comprises a substantially hollow, substantially conical shaped structure comprising a top end member and a plurality of adjacently positioned side members angularly extending from a top end member to a substantially circular bottom end. The top end member has a smaller diameter than the circular bottom end. The adjacently positioned side members are configured to provide multiple tiers in a vertical plane in the conically shaped structure. The multiple tiers comprise a plurality of apertures in a horizontal plane in the conically shaped structure. The plurality of apertures are configured for separating large debris particles, generally formed from coke and spent catalyst, from a flowing fluidized catalytic cracking stream, and directing the captured debris toward the circular bottom end of the device. A method of separating debris from a flowing stream is also provided. In particular, the device and method are useful for separating coke deposits in a fluidized catalytic cracking (FCC) process.
    • 用于从流动流中分离碎屑的装置,其包括基本上中空的基本上圆锥形的结构,其包括顶端部件和从顶端部件到大致圆形底端成角度地延伸的多个相邻定位的侧部部件。 顶端构件具有比圆形底端更小的直径。 相邻定位的侧构件构造成在锥形结构中的垂直平面中提供多个层。 多层在圆锥形结构中包括水平面中的多个孔。 多个孔被构造成用于从流动的流化催化裂化流中分离通常由焦炭和废催化剂形成的大碎片颗粒,并将捕获的碎屑引导到装置的圆形底端。 还提供了从流动流中分离碎屑的方法。 特别地,该装置和方法可用于在流化催化裂化(FCC)方法中分离焦炭沉积物。
