Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heating coils or heating jackets are used to heat hydrocarbon-containing material, then the hydrocarbon chains can be broken down, but coke and soot deposit on the heating coils and container walls, preventing thermal energy supply and making heating increasingly time-consuming and ultimately impossible
Solution Approach 1:
The harmful heating function is extracted from contact with the hydrocarbon material. Instead of heating coils or jackets being in direct contact with the material, a separate heater heats a heat transfer fluid that then circulates through heat exchanger coils immersed in the material, indirectly providing thermal energy without coke deposition
Solution Approach 2:
A heat transfer fluid acts as an intermediary between the heat source and the hydrocarbon material. The fluid absorbs thermal energy from the heater and transfers it through heat exchanger coils to the material, eliminating direct contact between heating elements and hydrocarbons that would cause coking
2Temperature
If heating is continued despite coke deposition, then the deposited substances prevent thermal energy supply, but increasing heating time or intensity does not solve the problem and ultimately makes heating almost impossible
Solution Approach 1:
Heat transfer fluid serves as an intermediary that efficiently transfers thermal energy from the heater to the hydrocarbon material through heat exchanger coils, preventing energy loss due to coke insulation on heating surfaces and ensuring consistent heating efficiency
Solution Approach 2:
The direct thermal conduction system (heating coils in contact with material) is replaced with a fluid-mediated heat transfer system, where convective heat transfer through circulating fluid provides more efficient and controllable energy transfer
3Productivity
If catalyst material is used to facilitate hydrocarbon splitting, then the conversion rate increases, but the catalyst material becomes clogged with deposited substances and ultimately becomes ineffective or completely ineffective
Solution Approach 1:
The harmful coking process is extracted and prevented by eliminating direct contact between catalyst and hydrocarbon material. The heater operates separately, heating a heat transfer fluid that indirectly heats the material, preventing coke formation that would clog the catalyst
Solution Approach 2:
The heat transfer fluid is preheated in a separate heater before contacting the hydrocarbon material through heat exchangers. This preliminary heating action ensures the material reaches cracking temperature without direct catalyst exposure to thermal degradation products that cause clogging
4Ease of operation
If agitator and pump are used to prevent deposited substances, then material circulation is improved, but they do not prevent the deposited substances from forming on heating surfaces and catalyst
Solution Approach 1:
Heat transfer fluid acts as an intermediary that eliminates the root cause of deposition. By transferring heat indirectly through heat exchanger coils rather than direct contact, the system prevents coke formation on heating surfaces, making agitation unnecessary for preventing deposition
Solution Approach 2:
The deposition problem is extracted and eliminated by removing the heating elements from direct contact with the hydrocarbon material. The heater heats a separate fluid that transfers thermal energy indirectly, preventing the chemical reactions that cause coking on heating surfaces

AI summary
The invention relates to a device for cracking hydrocarbon chains, comprising a container (1) with a container chamber (2) for receiving a fluid (7) that contains hydrocarbon chains, and a heating-flow device (3) for heating said fluid (7) in the container chamber (2). The heating-flow device (3) has a first discharge opening (15) for discharging a first partial flow of the fluid (7), and a second discharge opening (16) for discharging a second partial flow of the fluid (7). The first and second discharge openings (15, 16) are arranged such that the partial flows discharged from said discharge openings (15, 16) come into contact with one another in the container chamber (2) and are heated due to the conversion of the kinetic energy thereof into thermal energy. The heating-flow device (3) heats the partial flows to such high temperatures in the container chamber (2) that the hydrocarbon chains of the fluid (7) crack, at least in part, in said container chamber (2).
