Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coking drum designs fail to ensure homogeneous temperature distribution and even residue distribution during the coking process, posing hazards to operating personnel and affecting the efficiency of petroleum coke production.
Innovation Solution
A coking drum with a pipe bridge slide valve featuring an access opening at the level of the valve for feeding residues centrally, ensuring even temperature distribution, and a shut-off valve with an integrated delivery device for residue feeding, which includes a delivery opening and channel connected to a vacuum distillation chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If residues are fed into the coking drum through a feed opening located above the shut-off valve, then the drum can be sealed for automatic operation, but homogeneous temperature distribution and even residue distribution cannot be guaranteed
Solution Approach 1:
The feed opening is repositioned from the vertical dimension (above the shut-off valve) to the horizontal dimension (at the level of the shut-off valve in the drum wall), allowing residues to be fed centrally into the drum and achieve homogeneous distribution throughout the coking chamber
Solution Approach 2:
The feed opening is positioned at the optimal location (level of the shut-off valve) before the coking process begins, ensuring that residues are fed into the drum at the correct height to achieve homogeneous temperature and residue distribution from the start of the process
2Ease of operation
If manual opening of the coking drum is used, then operating personnel can directly observe and handle the process, but hazards from hot water, steam, loose coke pieces, dust, and toxic gases expose personnel to injury and health risks
Solution Approach 1:
The shut-off valve is extracted as a separate component between the coking drum and the external environment, allowing the drum to remain sealed during operation and only opening automatically when needed, thereby isolating personnel from harmful factors while maintaining operational capability
Solution Approach 2:
The shut-off valve acts as an intermediary device that controls the connection between the coking drum and the external environment, automatically opening to release pressure and allow coke removal, then sealing again to protect personnel from hot water, steam, and toxic gases
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures homogeneous temperature distribution and residue distribution within the coking drum, enhancing safety and efficiency in petroleum coke production by reducing hazards and improving process homogeneity.
Implementation Method 1
ensures homogeneous temperature distribution and residue distribution within the coking drum
Implementation Method 2
residues, in particular from a vacuum distillation process upstream of coking
Implementation Method 3
hydrocarbon chains are split at high temperatures. The group of thermal cracking processes includes so-called visbreaking and coking, in which carbon is deposited in a solid form, so-called coke or petroleum coke

AI summary
The invention relates to a coking drum, in particular for the production of petroleum coke, which has an approximately cylindrical base body and at least one inlet opening and one outlet opening, wherein a shut-off valve (1, 1') is arranged at the outlet opening and/or at the inlet opening. The coking drum is characterized in that at least one access opening (19, 19') for feeding residual materials, in particular from a vacuum distillation process upstream of the coking, is provided approximately at the level of the shut-off valve (1, 1').
