Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for separating CO isotopes, such as 13C16O from natural CO, require high power consumption due to the need for liquid nitrogen cooling, which increases energy costs and operational inefficiencies.
Innovation Solution
Implementing a heat pump cycle as a heating means in the rectification column system, which uses nitrogen as a working fluid to provide both heating and cooling capacities, reducing the reliance on external cooling sources and minimizing energy requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid nitrogen cooling is used in the rectification column system, then the separation of CO isotopes is achieved, but the power consumption increases significantly
Solution Approach 1:
The patent combines the cooling function (liquid nitrogen condenser) and heating function (electric heater) into a single heat pump system. The heat pump uses nitrogen as working fluid to provide both cooling at the top of the rectification column and heating at the bottom, eliminating the need for separate liquid nitrogen supply and reducing overall energy consumption while maintaining separation efficiency.
Solution Approach 2:
The heat pump system performs multiple functions simultaneously: it acts as both a condenser (cooling device) at the top of the column and a reboiler (heating device) at the bottom. This multi-functionality reduces the number of separate components needed and optimizes energy utilization by recovering heat from the condensation process to assist in the evaporation process.
2Stability of the object's composition
If electric heaters are used in each rectification section, then evaporation is maintained, but energy costs increase
Solution Approach 1:
The patent changes the energy supply parameters by replacing direct electric heating with heat pump-based heating. The heat pump delivers heat at the required temperature levels using compressed nitrogen, optimizing the energy input-output relationship and reducing overall energy costs while maintaining stable evaporation conditions in each rectification section.
3Manufacturing precision
If multiple rectification sections are arranged in chain-like manner, then separation precision is improved, but system complexity increases
Solution Approach 1:
The patent merges the cooling and heating systems into a single integrated heat pump unit that serves all rectification sections. This integration reduces the number of independent components and connections needed, simplifying the overall system architecture while preserving the multi-section chain-like arrangement required for high separation precision.
