Abstract
In some examples, coke, tar, or a mixture thereof can be removed from a furnace effluent. The furnace effluent can include coke, tar, or the mixture thereof and can be contacted with a first quench liquid to produce a quenched mixture, wherein the first quench liquid can include a first steam cracker naphtha, a first steam cracker gas oil, a first steam cracker quench oil, or a mixture thereof. The quenched mixture can be introduced into a first inlet of a centrifugal separator drum. A vapor product and a centrifugal separator drum bottoms can be separated from the quenched mixture, wherein the centrifugal separator drum bottoms can include at least a portion of the coke, tar, or the mixture thereof. The centrifugal separator drum bottoms can be recovered from a first outlet of the centrifugal separator drum.
