Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face inefficiencies and impracticalities in capturing and mitigating unintended emissions of gaseous fluids from compressor operations, often requiring additional equipment and procedures that yield unsatisfactory results.
Innovation Solution
A fluid diversion assembly is used to divert leakage gases and liquids from a compressor's cylinder to its intake or a collection apparatus, leveraging the compressor's operational pressure to enhance capture and mitigation, utilizing a diversion passage and valve to control fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If additional equipment and procedures are acquired and operated to capture emissions, then emission capture capability is improved, but device complexity and operational burden increase
Solution Approach 1:
The patent combines the emission capture function with the existing compressor sealing system by integrating a diversion passage directly into the packing assembly. This merging eliminates the need for separate capture equipment while maintaining emission mitigation capability, directly resolving the contradiction between capture effectiveness and device complexity
Solution Approach 2:
The compressor's own operational pressure is utilized to drive the diversion of emissions through the passage, eliminating the need for additional power sources or active control systems. The system serves itself by using its inherent operating conditions to achieve emission capture, reducing both equipment and operational complexity
2Object-generated harmful factors
If additional equipment and procedures are acquired and operated to capture emissions, then emission capture capability is improved, but operational burden increases
Solution Approach 1:
The system automatically utilizes the compressor's operational pressure to drive emission diversion without requiring external control or intervention. During normal compressor operation, pressure differential automatically propels emissions through the diversion passage, eliminating procedural burden while maintaining capture capability
Solution Approach 2:
The harmful emission flow is extracted and diverted through a dedicated passage integrated into the sealing assembly, separating the emission capture function from the main compression operation. This extraction allows emissions to be routed independently without interfering with compressor operation, reducing procedural complexity
3Device complexity
If compressor operational pressure is used to drive diversion, then additional equipment is eliminated, but pressure control requirements increase
Solution Approach 1:
The compressor's operational pressure automatically drives the diversion process without requiring external pressure sources or active pressure control systems. The pressure differential inherent in normal compressor operation is sufficient to propel emissions through the diversion passage, eliminating equipment while maintaining simple pressure management
4Object-generated harmful factors
If emissions are diverted to compressor intake, then emission mitigation is improved, but compressor intake requirements change
Solution Approach 1:
Instead of treating diverted emissions as harmful waste requiring separate handling, the system converts them into a beneficial resource by routing them back to the compressor intake for re-compression and utilization. This transforms the harmful emission flow into a useful portion of the compression cycle, improving mitigation while maintaining intake functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for efficient capture and mitigation of emissions without additional equipment, by diverting leakage fluids back into the compressor for compression or collection, thereby reducing environmental release.
Implementation Method 1
The diversion passage may be positioned to provide a flow path for a gas at a first pressure from the cylinder, thereby to divert leakage gas from the cylinder
Implementation Method 2
a valve associated with the diversion passage and positioned to control pressure in the diversion passage, thereby to enhance diversion of the leakage gas

AI summary
Embodiments of assemblies and methods to enhance diversion of fluid, including gas and/or liquid, passing from a cylinder of a compressor to an interior cavity of the compressor, may include a diversion assembly including a diversion passage positioned to extend at least partially through a packing assembly of the compressor. The diversion passage may be positioned to provide a flow path for fluid, including a gas and/or liquid, at a first pressure from the cylinder, thereby to divert leakage fluid, including gas and/or liquid, from the cylinder to one or more of an intake of the compressor during operation or a collection passage. Embodiments of the assemblies and methods further may include a valve associated with the diversion passage and positioned to control pressure in the diversion passage, thereby to enhance diversion of the leakage fluid to the one or more of the intake of the compressor or the collection apparatus.
