Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and limited availability of conventional methods for delivering compressed natural gas (CNG) to remote locations, where constructing a pipeline is excessive or impossible, hinder the installation of new CNG re-fueling stations and restrict the use of CNG by vehicles and industries.
Innovation Solution
A system comprising modular storage units, loading and unloading platforms, and a transportation sequence that allows for the efficient delivery and refueling of CNG, using interconnected cylinders with safety valves and anti-corrosion treatments, and a rotating cascade sequence to manage pressure and optimize gas usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pipeline extension is used to deliver CNG to remote locations, then reliable gas supply is ensured, but construction cost becomes excessive or impossible
Solution Approach 1:
The system divides the gas delivery function into separate mobile components: storage modules with interconnected cylinders that can be transported independently to remote locations, eliminating the need for continuous pipeline construction while maintaining reliable gas supply through modular replacement and refilling
2Ease of operation
If high-pressure vessels are used to transport CNG to remote stations, then gas delivery is achieved, but operational cost and limited availability increase
Solution Approach 1:
The storage modules are designed to be self-sufficient units with integrated safety valves and anti-corrosion treatments, requiring minimal external infrastructure or specialized handling equipment, thereby reducing operational costs and increasing availability for remote refueling stations
3Duration of action of stationary object
If multiple separate pressure vessels are used for CNG storage, then gas supply continuity is maintained, but system complexity and space requirements increase
Solution Approach 1:
Multiple cylinders are interconnected through a common manifold system within a single integrated storage module, allowing gas to be drawn from any cylinder while maintaining continuous supply, thereby reducing system complexity compared to completely separate vessel arrangements

AI summary
The present invention is referred to a transportable compressed natural gas supply system. This system is an integral solution for supplying compressed natural gas (CNG) to remote places that can not have access to the gas pipelines. It consists of storage modules (3), loading and unloading platform (4-32), a transport vehicle and a sequence of use of said modules (3). The modules (3) are formed by a protection cage with fibreglass lids having cylinders inside for the compressed natural gas. These cylinders are interconnected with pipes, and they also have lock, relief, excess and pressure gauge valves. Besides, these cylinders are separated from each other by rubber separators. The system is formed by loading and unloading platforms of the modules (3), a transport vehicle to help in replacing them and a sequence of use.
