Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current distillation processes using a single column face limitations in both efficiency and capacity, as connecting multiple columns in series can only maintain the processing capacity of a single tower, restricting operational flexibility and efficiency.
Innovation Solution
A selective distillation apparatus that can switch between serial and parallel connection modes by using two distillation columns with a piping system and control mechanism, allowing for high-efficiency operation in serial mode and high-capacity operation in parallel mode without shutdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two distillation columns are connected in series to achieve high-stage separation, then separation efficiency is improved, but processing capacity remains limited to that of a single tower
Solution Approach 1:
The patent implements dynamic reconfigurability by providing multiple piping connections (first connecting line, second connecting line, third connecting line) that allow the system to switch between series and parallel configurations. The control part dynamically adjusts the connection mode based on operational requirements, enabling the system to adapt between high-efficiency series mode and high-capacity parallel mode without physical reconfiguration or shutdown.
2Ease of operation
If a single distillation column is used to maintain simple operation, then operational simplicity is preserved, but both efficiency and capacity are limited
Solution Approach 1:
The patent creates a multi-functional distillation system where two columns can operate in multiple modes: series connection for high-stage separation, parallel connection for high-capacity operation, and individual independent operation. The control part统一管理 all switching operations, maintaining ease of operation while enabling the system to perform multiple functions (high-efficiency mode, high-capacity mode, flexible adaptation mode) that a single column cannot achieve.
3Stability of the object's composition
If distillation columns operate in fixed configuration, then system stability is maintained, but operational flexibility is restricted
Solution Approach 1:
The patent implements dynamic reconfigurability by providing multiple piping connections (first connecting line, second connecting line, third connecting line) that allow the system to switch between series and parallel configurations. The control part dynamically adjusts the connection mode based on operational requirements, enabling the system to adapt between high-efficiency series mode and high-capacity parallel mode without physical reconfiguration or shutdown.
Solution Approach 2:
The patent changes the operational parameters of the distillation system by switching between different connection configurations. The control part adjusts parameters such as connection mode (series/parallel), reflux ratios, and feed distribution to optimize system performance for different operational scenarios, thereby achieving both stability through controlled parameter management and flexibility through parameter variability.
