Engineering Contradiction Analysis
1Use of energy by moving object
If mechanical separation is performed before pressure reduction to separate high viscosity and low viscosity fractions, then energy consumption is reduced and product quality is improved, but device complexity increases
Solution Approach 1:
The process separates the hydrocarbon mixture into different viscosity fractions through mechanical separation before pressure reduction. The high viscosity fraction and low viscosity fraction are processed separately, allowing optimized energy consumption for each fraction while improving overall product quality through selective treatment.
Solution Approach 2:
Mechanical separation is performed as a preliminary step before pressure reduction and further processing. By separating high viscosity and low viscosity fractions beforehand, the subsequent processing steps can be optimized for each fraction, reducing overall energy consumption and improving product quality.
2Ease of manufacture
If high viscosity compounds are removed through mechanical filtration, then downstream processing is simplified and product quality is enhanced, but device complexity and operational complexity increase
Solution Approach 1:
High viscosity compounds are extracted and removed from the hydrocarbon mixture through mechanical filtration before pressure reduction. This preliminary removal of problematic high viscosity fractions simplifies downstream processing operations and enhances the quality of the final low viscosity hydrocarbon product.
Solution Approach 2:
Mechanical filtration is implemented as a preliminary step to remove high viscosity compounds before the main processing steps. This preliminary action prevents these compounds from interfering with subsequent processing operations, thereby simplifying downstream processing and improving product quality.
3Use of energy by moving object
If mechanical separation is implemented to separate hydrocarbon fractions, then energy consumption is reduced, but the system requires complex temperature control and fluid management
Solution Approach 1:
The process utilizes controlled temperature changes to manage the viscosity characteristics of hydrocarbon fractions during mechanical separation. By adjusting temperature parameters, the system optimizes the separation efficiency while maintaining manageable operational conditions, balancing energy reduction with operational ease.
