Title: "residuum feed injection in transfer line coking"
IPC: C10B55/08
Filed: 1958-04-02
Abstract: 847,429. Coking oils. ESSO RESEARCH & ENGINEERING CO. April 2, 1958 [April 10, 1957], No. 10667/58. Class 55 (1). In a transfer line coking process in which hot inert particulate solids such as coke are fed into the transfer line 1 through a riser 2 entrained in a fluidising gas such as steam injected at 3, the heavy hydrocarbon oil feed is injected through line 4 in a direction which is countercurrent and axially opposed to the direction of flow of the solids, to permit the feed to contact the solids prior to contacting the surface of the transfer line reactor 1. The feed may be injected where there is a concentration of solids due to a change of direction of 45 to 90 degrees. The product gases are separated in cyclose 5 and pass through line 6 to be quenched. The cracking contact time is 0.2 to 0.4 seconds.

A sheet of blotting paper 36 is placed over the face of the plate and over this a strap member 30 is placed which is secured to members 32 which are adjusted by screws 34 so as to exert a pressure on the plate by the strap 30. Registering holes are provided in the edges of the backing sheet co-operating with pins 28. The sheet 22 is provided with apertures 40 for plate hooks. After cooling the edges of the plate are bevelled.
