Firstly, coking along the vapor line of the coke tower is a common problem in this type of operation. In daily operations, it is necessary to prevent the temperature of the main oil and gas line at the top of the tower from rising too high. It is also important to check whether there is any uneven flow in the quench oil (i.e., if one of the flow paths is blocked or the flow rate is low). Additionally, factors such as the caking tendency associated with the properties of the raw materials, the level of the raw material stock, and the quality of the quench oil must also be taken into account. If coking occurs, cleaning holes can be installed at the pipeline elbow as part of the design changes; cleaning can be carried out once the coking has been removed
