Solar Air Pneumatic Controller for Low-Emission Tank Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Natural gas supplied controls often vent undesirably, expelling hydrocarbons and increasing emissions, necessitating a more environmentally friendly and cost-effective method for supplying and venting pneumatic controls.
Innovation Solution
A solar-powered air regulated controller (SPARC) system that uses air instead of natural gas to power pneumatic systems, reducing emissions by venting with pure air and incorporating a mount and switch system to convert high-bleed systems to low-bleed operations, utilizing a three-way valve for gas routing to burners or flares.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If natural gas supplied controls are used to power pneumatic systems, then the system can operate with sufficient power, but hydrocarbons are expelled during venting resulting in increased emissions
Solution Approach 1:
The patent introduces an intermediary substance (air from atmospheric source or storage tank) that replaces natural gas for the venting function. The air regulator controller uses this intermediary to power the pneumatic system during normal operation, eliminating hydrocarbon emissions while maintaining sufficient pneumatic power. The intermediary substance serves as a mediator between the power source and the pneumatic system.
2Object-generated harmful factors
If air is used instead of natural gas to power pneumatic systems, then emissions are reduced, but the system requires additional components like air regulators and storage tanks
Solution Approach 1:
The air regulator controller is designed to perform multiple functions: it regulates air pressure from atmospheric sources, manages storage tank pressure, controls pneumatic valve operation, and interfaces with existing control systems. This multi-functional device consolidates what would otherwise require separate components, reducing overall system complexity while enabling emission-free operation.
Solution Approach 2:
The system incorporates automatic pressure regulation and control mechanisms that operate without continuous human intervention. The air regulator automatically maintains proper pressure levels, the controller monitors system status, and the pneumatic valves self-regulate flow based on pressure differential, reducing the need for complex external control systems.
3Ease of manufacture
If existing pneumatic systems are converted to use air instead of natural gas, then capital cost is reduced compared to traditional mizers, but conversion complexity increases
Solution Approach 1:
The conversion system is divided into modular components: an air regulator unit, a controller module, and interface adapters that can be independently installed and configured. This segmentation allows for phased conversion of existing systems, reducing upfront capital requirements and enabling step-by-step implementation while managing conversion complexity through manageable modules.

AI summary
A system for an air regulated controller. In one embodiment, a solar powered air regulated controller is disclosed. This allows the tanks to be pneumatically controlled via ai rather than wet gas. The result is significant emissions reduction. Additionally, as less wet gas is used for venting, more is directed to the downstream sales line.
