WebAug 9, 2016 · Coking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products. As the name implies, the end product is petroleum coke, a coal-like material. Types of coking. Two types of coking processes exist — delayed coking and fluid coking. WebIn a delayed coking process the feed is heated in a furnace to cracking temperature, typically (485–505)°C, and it is then injected into a process vessel called the coking …

Webcoker gas composition is given in Table below. Fluid Coking Fluid coking is a thermal cracking process consisting of a fluidized bed reactor and a fluidized bed burner as shown in Figure below. Vacuum residue is heated to 260 °C (500 F) and is fed into the scrubber which is located above the reactor for coke fine particle recovery, WebFeb 16, 1998 · As shown in Fig. 3, the delayed coker case produces much less liquid product. The total C4+ liquid product in the delayed coker case is only 24,200 b/sd, … WebTraditionally, to minimize the quantity of coke formed, the pressure in the coke drum is set at minimum levels. In today's delayed cokers, the minimum practical pressure level is 6.89 x 10⁴ to 1.03 x 10⁵ Nm⁻² (10 to 15 psig). To achieve lower pressures requires large and expensive equipment with high compression requirements. cspf swim
