Integrated CO2 Compressor-Pump With Single Bull Gear Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for compressing and pumping CO2 or CO2 mixtures require separate compressors and pumps, which are often inefficiently matched, leading to high costs and large footprints due to the need for precise coordination and separate manufacturing, and are not optimized for reducing emissions effectively.
Innovation Solution
An integrated system with a compressor part and a pump part, driven by a single bull gear, where the compressor part compresses CO2 from a gas phase to a dense phase using multiple impellers and cooling devices, and the pump part then pumps the fluid in the dense phase to a higher pressure, with the bull gear's rotational speed coordinating both stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate compressors and pumps are used for CO2 compression and pumping, then the system can handle the phase change from gas to dense phase, but the system footprint and manufacturing complexity increase due to the need for precise matching between compressor and pump
Solution Approach 1:
The patent combines the compressor and pump into a single integrated machine where the compressor section compresses CO2 from gas phase to dense phase, and the pump section immediately pumps the dense phase CO2. This merging eliminates the need for separate compressor and pump units, reducing system footprint while ensuring precise phase matching between compression and pumping operations.
Solution Approach 2:
The integrated machine performs multiple functions within a single device: compression of gas phase CO2, phase transformation to dense phase, and pumping of dense phase CO2. This multi-functionality eliminates the need for separate specialized equipment while maintaining operational efficiency.
2Ease of manufacture
If separate compressors and pumps are manufactured by different providers, then each component can be optimized independently, but the coordination and matching between components becomes time-intensive and costly
Solution Approach 1:
By integrating the compressor and pump into a single machine manufactured as one unit, the patent eliminates the need for coordination between different manufacturers. The entire system is designed and manufactured together, ensuring seamless integration while maintaining the ability to optimize each section for its specific function.
3Ease of repair
If traditional separate compressor and pump systems are used, then each component can be independently maintained, but the overall system cost and complexity increase
Solution Approach 1:
The integrated machine is divided into distinct functional sections: a compressor section with impellers for gas phase compression, a phase transformation section with cooling devices, and a pump section with impellers for dense phase pumping. Each section can be independently maintained or repaired while remaining part of the integrated system, combining the benefits of component independence with system integration.
