Conventional flue gas cleaning systems are costly and vary in effectiveness, struggling to meet stringent governmental regulations for pollutant reduction in flue gas emissions from industrial sources.

Innovation Solution

A flue gas reclamation system comprising a combustion engine, generator, compressor, holding tanks, and an algae farm, where flue gas is processed and enriched, then supplied to an algae farm for carbon dioxide utilization, reducing pollutants and providing nutrients for algae growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional flue gas cleaning systems (electrostatic precipitators, gas scrubbers, dust filters) are used to remove pollutants, then pollutant removal efficiency is improved (90 percent or more), but installation and operating costs increase significantly

Engineering Contradiction:
Improvepollutant removal efficiencyVSAvoidinstallation and operating cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The system converts harmful flue gas emissions into a beneficial resource by directing them to an algae farm, where the algae consumes carbon dioxide and produces biomass. This transforms a waste stream requiring expensive treatment into a valuable input for renewable fuel production, eliminating the need for conventional expensive cleaning systems while meeting emission regulations.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The system changes the destination and utilization parameter of flue gas from atmospheric discharge to controlled delivery to algae cultivation systems. By altering how the flue gas is handled (from removal to utilization), the system achieves pollutant reduction without requiring expensive conventional cleaning infrastructure.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If conventional flue gas cleaning systems are installed to meet governmental regulations, then compliance with emission limits is improved, but system complexity and variety of treatments required increase

Engineering Contradiction:
Improveregulation complianceVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The algae farm serves multiple functions simultaneously: it acts as a carbon dioxide sink, produces renewable biomass/fuel, and functions as a natural flue gas treatment system. This multi-functional approach replaces the need for multiple specialized cleaning devices (precipitators, scrubbers, filters) with a single integrated system that handles pollutant removal while generating valuable byproducts.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The algae farm naturally performs the cleaning function through biological processes. The algae self-regulates by consuming carbon dioxide and other flue gas components, requiring minimal external intervention or complex control systems compared to conventional mechanical cleaning devices.

Inventive Principle:
Principle #25Self-service
