  • System and method for producing needle coke
    Patent number: 11946003
    Abstract: A system for producing needle coke and a method for producing needle coke using the system are provided. The system includes a coke tower, a pressure stabilization tower, a buffer tank and a coking fractionation tower. A pressure controller is provided at the top of the pressure stabilization tower for adjusting the pressure at the top thereof. An oil gas outlet of the coke tower is in communication with an oil gas inlet of the pressure stabilization tower through a pipeline. No pressure controller for adjusting the pressure at the top of the coke tower is provided in the coke tower or on the oil gas pipeline connecting the coke tower to the pressure stabilization tower.
